Objectives: The current study aimed to conduct a phytochemical screening of commonly known fruit red grape (Vitis vinifera L.) seed methanolic extract through gas chromatography and mass spectrometry (GC-MS) to identify the bioactive compounds responsible for its health benefits and evaluate the pharmacological potentialities of the extract and its fractions against oxidation, inflammation, pain, and diarrhea. Methods: The in vitro antioxidant, anti-inflammatory, and cytotoxic characteristics of methanolic extracts and various solvent fractions of V. vinifera were evaluated using the DPPH free radical scavenging assay, membrane stabilizing, and brine shrimp lethality bioassay. Furthermore, the study assessed the effects of crude extracts (200, 400, and 600 mg/kg of body weight) on pain relief and reduction of diarrhea in animals using methods such as tail immersion, the acetic acid-induced writhing technique, and a diarrheal mouse model induced with castor oil. Results: A total of 73 phytoconstituents were predominantly found in the seed extract based on the GC-MS analysis. Among the identified compounds, 9-octadecenamide (13.7%), and (9E,11E)-octadeca-9,11-dienoate (11.07%) are most abundant. Several notable constituents, such as gamma-sitosterol, stigmasterol, paromomycin, 4,6-cholestadienol, gamma-tocotrienol, 24-Propylidenecholest-5-en-3beta-ol, and alpha-tocopherol acetate, are also present. The methanolic extract of V. vinifera seed and its different solvent fractions showed promising antioxidant properties (IC50 = 1.19-17.42 µg/mL) compared to the standard antioxidant butylated hydroxytoluene (IC50 = 20.46 µg/mL). Aqueous soluble fraction exerted inhibition of nearly 50% heat-induced hemolysis compared to the standard acetylsalicylic acid (42%). Besides, all the tested doses (200, 400, and 600 mg/kg bw) of the crude extract showed significant (P <.05) analgesic and antidiarrheal effects. Conclusion: The current findings endorsed the health benefits of V. vinifera by revealing potent antioxidant, anti-inflammatory, analgesic, and antidiarrheal effects. Nevertheless, further in-depth analysis of the plant's chemical constituents and pharmacological effects on health is warranted for novel drug discovery from V. vinifera. [ABSTRACT FROM AUTHOR]

Introduction: Colocasia affinis Schott (Family: Araceae), found in the Asian region, is a traditional root vegetable consumed by the locals and well-known as Dwarf Elephant Ear. Methods: For the pharmacological exploration of this root vegetable, four kupchan fractions (i.e. HSF, DCMSF, EASF, and AQSF) from ethanolic extract of C. affinis were employed to in vitro i.e. antioxidant, cytotoxicity, and antimicrobial and in vivo i.e. antidiarrheal and analgesic assays, followed by phytochemical screening and GC-MS protocol. Result and Discussion: In the antioxidant assay, the AQSF showed promising potential with an IC50 value of 29.4 µg/mL and additionally, it exhibited the greatest overall phenolic content, measuring 57.23 mg GAE/gm. of extract among other fractions. The AQSF also revealed promising cytotoxic activity in brine shrimp lethality assay with an LC50 value of 1.36 µg/mL. Both AQSF and EASF exhibited substantial antimicrobial efficacy against both gram-positive and gramnegative bacteria as well as various fungus species with a remarkable zone of inhibitions compared to standards. Whereas, during both the castor oil-induced antidiarrheal and acetic acid-induced writhing assay, the DCMSF at 400 mg/kg dose exhibited the highest 51.16% reduction of diarrhea and 52.33% reduction of writhing. Phytochemical screening revealed several chemical groups while GC-MS study of different fractions of dwarf elephant ear ethanolic extract revealed 48 different bioactive phytochemicals in total. Several targets such as KAS, DHFR for anti-microbial activities, GLR, URO for antioxidant activities, EGFR, BCL-2 for cytotoxicity, KOR, DOR for antidiarrheal activities and COX-2, TNF-a for analgesic activities are considered for molecular docking against identified phytocompounds and standards along with ADME/T studies to ascertain their safety, efficacy and drug likeliness profiles. Conclusion: To recapitulate, our study revealed that vegetables such as dwarf elephant ear can be considered as a prospective source of therapeutics and drug development besides their nutritive food values.

Syzygium genus is extensively used in managing different diseases such as antimicrobial, antidiarrheal, antidiabetic, analgesic, anti-inflammatory, antioxidant, and anticancer activities. The present study aims to investigate phytochemicals by screening tests and GC-MS analysis and evaluate the antioxidants, cytotoxicity, analgesic, and anti-diarrheal activity of the extracts of the leaves of Syzygium reticulatum. The leaves of the S. reticulatum were extracted with hexane and methanol by the maceration process successively, denoted as SRH and SRM. The extract's phytochemical analyses found flavonoids, alkaloids, saponins, tannins, glycosides, and carbohydrates. The GC-MS analysis of the methanol extract identified 8 compounds. The major components were identified as Diisooctyl phthalate (96.903 %), 2-methyltetracosane (1.094 %), and others with fewer amounts. The result of the antioxidant study of the extracts as total phenolic content of SRH 8.92 ± 0.62 and SRM 340.107 ± 11.11 mg/g, respectively, total flavonoids content of SRH 7.85 ± 0.71 and SRM 105.16 ± 0.93 mg/g, IC50 values of the DPPH (2,2-diphenyl-1-picrylhydrazyl) free radical scavenging assay of SRM was 14.67 μg/mL, SRH was 41.26 μg/mL and ascorbic acid 14.08 μg/mL; the total antioxidant capacity of SRH was 21.33 ± 2.52 mg/g, whereas SRM was 353.71 ± 4.59 mg/g. The results of these studies suggest that methanol extract has a more potent antioxidant capacity than hexane extract. The methanol extract also exhibited higher toxicity (LC50 value 49.99 μg/mL) compared to hexane extract (LC50 value 370.348 μg/mL), as revealed by the Brine shrimp nauplii cytotoxic study. An analgesic study of the methanol extract found that a lower dose (250 mg/kg) has more significant analgesic activity than the higher dose and standard drug aspirin. At 90 min, the hot plate's highest percentage of latency elongation was 110.32, while the acetic acid-induced writhing inhibition was 63.04 %. At a dose of 500 mg/kg, the methanol extract also shown good efficacy in mice suffering from castor oil and magnesium sulfate-induced diarrhea. The findings from the study of the leaves of the S. reticulatum exhibited that methanol extracts have significant antioxidant, cytotoxic, analgesic, and anti-diarrheal activity.

Diarrheal infections remain a public health problem. The mainstays of pharmacological therapy for infectious diarrhea include probiotics, antibacterial, and intestinal adsorbents. Nevertheless, these clinical treatments are not devoid of shortcomings including prohibitive costs and adverse effects. Medicinal plants including Plectranthus barbatus(P. barbatus) have folkloric remedies against diarrhea. However, there is paucity of knowledge to scientifically validate the efficacy of P. barbatus on diarrheal infections. This study was undertaken to ascertain antidiarrheal efficacy, bioactive composition, and toxicity profiles of P. barbatus extracts. Antidiarrheal activity and acute toxicity were carried out on Swiss albino mice. Quantitative phytocompound analysis was evaluated using liquid chromatography-mass spectrometry(LCMS). Results indicated that P. barbatus extract has antidiarrheal activity whereby it prolonged the start of diarrhea, causing a decline in the occurrence of wet feces and intestinal transit significantly. Additionally, the extract reduced the accumulation of intraluminal fluid resulting in the decrease in distension, intestinal overload, and water content in the fecal drops. Acute toxicity assay on mice showed that P. barbatus extract was non-toxic at the dosage level of 2000mg/kgbw(milligram/kilogram body weight). LCMS analysis detected presence of phytocompounds associated with antidiarrheal effects including forskolin, gallic, kaempferol, and quercetin. Findings from the current study offer a scientific validation for the folkloric utilization of P. barbatus in the management of diarrhea. [ J Adv Biotechnol Exp Ther 2024; 7(1.000): 239-254]

Although the conventional usage of Sphaeranthus indicus flowers in medicine exists, there is a lack of research on the precise pharmacological characteristics and comprehensive phytochemical composition of its flowers, resulting in a knowledge gap on their whole therapeutic capabilities. The aim of this work is to identify and describe the phytochemicals found in the flowers of Sphaeranthus indicus and assess specific pharmacological effects, such as antioxidant, antibacterial, anti-inflammatory, thrombolytic, antidepressant, and antidiarrheal characteristics. The investigation revealed that the MESIF (methanol extract of S. indicus flowers) showed substantial antioxidant performance (IC50 = 26.33) accompanied by a moderate phenolic content (93.33 ± 1.76).

The objective of the current study was to evaluate the potential of Punica granatum L peel in mice as an antidiarrheal and antidiabetic agent. In an antidiarrheal study, different doses (50, 100, 150, and 200 mg/kg) of methanolic pomegranate peel extract (PPE) were administrated to castor oil-induced (1 mL/kg) diarrheal mice. Mice administered loperamide hydrochloride (3 mg/kg) were treated as a baseline group. During the experiment, electrolyte and hematological levels were analyzed, and at the end, histopathology of the intestine was performed. For antidiabetic activity, PPE doses (50, 100, 150, and 200 mg/kg) and metformin hydrochloride were administered to alloxan-induced (150 mg/kg) diabetic mice groups, and biochemical and hematological parameters were analyzed. Liver histopathology was done at the end of the experiment. The study found that castor oil caused diarrhea and had a significant (p < 0.05) impact on hematological parameters and electrolyte levels, compared with negative control group. PPE helped to restore altered parameters to normal levels. Histopathology of positive control group revealed abnormal cell structures, with irregularly arranged villi, unclear mucosal architecture of the ileal section, and nuclei cells were damaged and prone to collapsing. Significant dose-dependent recovery was observed in PPE-fed mice groups. After inducing and confirmation of diabetes with alloxan, all groups, except the negative control group, had significantly high glucose levels (p < 0.05). Levels of C-reactive protein and bilirubin were significantly altered, but PPE and metformin hydrochloride showed potential to improve these parameters. In positive control group mice, liver histology showed microvesicular fatty changes throughout the acinus, reactive Kupffer cells, mid-portal inflammation, reduced portal triad, centrilobular visibility, and well-differentiated central vein with well-formed nuclei. Similarly, significant dose-dependent recovery was observed in PPE-administrated mice groups. These results demonstrated that PPE had promising antidiarrheal and antidiabetic potential.

Background: Liver disease is any disease that negatively affects the normal function of the liver, and it is a major health problem that challenges not only healthcare professionals, but also the pharmaceutical industry and drug regulatory agencies. Similarly, diarrhea is the second leading cause of death among children under five globally next to pneumonia. The available synthetic drugs for the treatment of liver disorders and diarrhoea have limited safety and efficacy. Objective: To evaluate the in vivo hepatoprotective and antidiarrheal activities of hydroalcoholic leaf and fruit extracts of Schinus molle L. (Anacardiaceae) in mice. Methods: Hepatoprotective activity of the extracts was evaluated by using CCl4 induced hepatotoxicity in mice model. In this model, mice were divided into groups and treated as follows. The normal control and toxicant control groups were treated with the vehicle used for reconstitution, the positive control was treated with the standard drug (silymarin), and the test groups were treated with different doses of plant extracts daily in the morning for seven days. Additionally, all groups except the normal control were treated with CCl4 (2 mg/kg, IP) on the 4th day of treatment, 30 min post-dose. On the 7th day, blood was collected from each mouse via a cardiac puncture. The collected blood was centrifuged, and serum levels of ALT, AST, and ALP were determined using an automated chemistry analyser. Data were analysed using one-way analysis of variance (ANOVA) followed by Tukey's post-hoc test.The antidiarrheal activity of the extract was investigated using castor oil-induced diarrhoea, enteropooling, and small intestine transit. The test groups received various doses (100, 200, and 400 mg/kg) of the extract, whereas the positive control received loperamide (3 mg/kg), and the negative control received the vehicle (distilled water, 10 ml/kg). Result: Hepatoprotective activity: The leaf and fruit crude extracts showed significant improvement in the body weight and liver weight of mice compared to the untreated toxicant control. Additionally, treatment with hydromethanol leaf and fruit extracts caused a significant (P 0.05) the level of albumin compared with the toxicant control.Antidiarrheal activity: In the castor oil-induced diarrheal model, the 80 % methanol extract delayed the onset of defaecation and significantly reduced the number and weight of faeces at all tested doses compared to the negative control. In the enteropooling test, 80 ME significantly (P

Diarrhea is a global major health problem reported by 2.5 billion cases annually. Diarrhea accounts for 9% of child death worldwide or the second leading cause of death among toddlers. Many local people have used traditional medicine for diarrhea therapy. Dragon fruit is a herbal plant with high vitamins and various nutritious compounds. Therefore, this study determined antidiarrheal activity from dragon fruit peel methanolic extract (Hylocereus polyrhizus). This study was experimental with in vitro and in vivo models. The in vitro model used disc diffusion and microdilution assay against the diarrhea-causing pathogen (Escherichia coli). Meanwhile, the in vivo model used male Wistar rats induced by Castro oil. This study showed that the minimum inhibitory concentration (MIC) and minimum killing concentration (MKC) of dragon fruit peel extract against Escherichia coli were 50 and 100 mg/ml, respectively. The increased dose of dragon fruit peel methanol extract has increased the antidiarrheal index. The highest and lowest antidiarrheal index was found in the dragon fruit methanol extract-3 (76.56%) and dragon fruit methanol extract-1 (43.28%). The dragon fruit peel methanol extract can be proposed as antidiarrhea and antibacterial therapy against the diarrhea-causing pathogen.

Background: Malay rose apple (Syzygium malaccense) fruit has been used for a long time as a traditional medicine for diarrhea by the community. Malay rose apple fruit contains active compounds such as flavonoids, tannins, and terpenoids and could be used as an antidiarrheal drug. Objective: This study aims to test the effectiveness of the infusion of Malay rose apple fruit as an antidiarrheal agent in mice (Mus musculus). Methods: This research uses the method of intestinal protection and intestinal transit. The experimental animals in this study were 25 mice, which were divided into 5 groups, consisting of negative control (1% Tween 80), positive control group (loperamide HCl), and treatment groups using infusion of Malay rose apple fruit at concentrations of 50%, 75%, and 100%. The parameters assessed in the intestinal protection method are the frequency of defecation and the consistency of the stool, while the intestinal transit method is the ratio of marker passages. Results: The results showed that the antidiarrheal effect occurred at all concentrations. The best concentration as an antidiarrhea is shown by infusion with a concentration of 50%. The 50% concentration group had the smallest average on defecation frequency, stool consistency, and marker passage ratio compared to the values of the other treatment groups and was significantly different (P

Background: Salvia urica Epling is taxonomically and phylogenetically related to Salvia amarissima Ortega. The last species has pharmacological relevance by its contents of bioactive metabolites. Nowadays, Salvia urica has no reports about its chemical constituents and pharmacological activities. Hypothesis: Does the close relationship between S. amarissima and S. urica led both species produce similar specialized metabolites? Does Salvia urica display similar pharmacological effects as S. amarissima? Studied species: Salvia urica Epling (Lamiaceae). Study site and dates: The plant material was collected in Teopisca, Chiapas, Mexico, in December 2021. Methods: Metabolites of the acetone extract from Salvia urica were identified by GC-MS and HPLC-PDA profiling. In parallel, a phytochemical study was conducted, and the individual purified constituents, previously characterized by 1D NMR, were assayed on antihyperglycemic effect in diabetic mice and a charcoal-gum arabic-induced hyperperistalsis model in rats. Results: The volatile compounds identified by GC-MS were alkanes, aromatics and triterpenes. The principal constituents of the acetone extract of Salvia urica were amarissinin A and 5,6-dihydroxy-7,3',4'-trimethoxyflavone, which were also quantified by HPLC-PDA. The extract and both metabolites isolated showed an antihyperglycemic effect on streptozotocin-induced diabetic mice, suggesting a possible synergic effect. In addition, the compound 5,6-dihydroxy-7,3',4'-trimethoxyflavone (IC50 = 0.79 mg/kg) showed a better antipropulsive effect than loperamide (IC50 = 16.6 mg/kg). Conclusions: The phytochemical composition of an acetone extract of Salvia urica was determined by first time. The metabolites isolated from this plant support the phylogenetic relationship of S. urica with Salvia amarissima, and they showed antipropulsive and antihyperglycemic effects.

Background and Aims: The study aimed to evaluate the pharmacological properties of methanolic extracts of leaves and barks of Woodfordia fruticosa (L.) Kurz (family: Lythraceae) focusing on antioxidant, thrombolytic, anti‐inflammatory, antibacterial, analgesic, and antidiarrheal effects. Methods: 1,1‐Diphenyl‐2‐picrylhydrazyl (DPPH) free radical scavenging assay, clot lysis, disc diffusion, and membrane stabilizing methods were employed to assess in vitro antioxidant, thrombolytic, antibacterial, and anti‐inflammatory properties of the leaf and bark methanolic extracts (ME) of W. fruticosa and different organic solvents, that is, petroleum ether (PE), dichloromethane (DCM), chloroform (CL), and aqueous (AQ) fractions. In addition, in vivo central and peripheral analgesic and antidiarrheal activities of both crude extracts were evaluated at two doses (200 and 400 mg/kg of body weight [bw]). Results: All the extracts and fractions showed promising antioxidant properties by scavenging DDPH free radicals with IC50 of 6.11–20.79 μg/mL. AQ fraction (41.24%) of leaves and ME (44.90%) of bark exerted notable in vitro thrombolytic activity. The CL fraction of leaves and AQ fraction of the bark showed 43.16% and 45.37% inhibition of RBC hemolysis, respectively, compared to the inhibition of RBC hemolysis by aspirin in a hypotonic‐induced membrane stabilizing assay. Besides, both extracts were observed to provide significant (p < 0.001) central and peripheral analgesic responses at both doses of 200 and 400 mg/kg bw. Furthermore, both doses of bark extract (p < 0.001) and the 400 mg/kg bw of leaf extract (p < 0.05) were observed to possess statistically significant antidiarrheal activity. Additionally, in an in vivo acute toxicity investigation, both extracts had a median lethal dose (LD50) greater than 5000 mg/kg bw, indicating their safety level. Conclusion: The current study proves the ethnomedicinal uses of W. fruticosa; however, further studies are required for phytochemical screening to isolate the responsible bioactive compounds and discover the lead molecules from the plant species.

Satureja montana L. (SM) has a long traditional use as a spice and a medicine for various gastrointestinal disorders, including painful spasms and diarrhea. Contrary to conventional drugs, administration of SM and its extracts are considered safe. Previous studies have shown that the essential oils (EOs) of SM from different areas are rich in monoterpenes, sesquiterpenes, diterpens, and phenolic compounds, including flavonoids, tannins, and acids with great composition variability. Determination of composition of EO from Herzegovinian SM done by gas chromatographyflame ionization detection and gas chromatography mass spectrometry (GC-FID and GC/MS, respectively) revealed carvacrol as a primary substance followed by γ-terpinene, p-cymene, and ß-caryophyllene. Ex vivo spasmolitic activity caused by EO was evident in different types of isolated rat ileum function with the most potent effect on spontaneous activity followed by electrical field stimulation and KCl- and CaCl2-induced activity. SMEO produced in vivo antidiarreal activity on castor oil-induced diarrhea in young rats and showed the potential to cause a decrese water content in the feces of adult Wistar rats. This study indicates that effects of SM on the intestinum could be mediated through combination of Kv channel activation and Ca channel blockade, but additional mechanisms might be involved. The results of this study corroborate the traditional use of SM as antispasmodic, antidiarrheal, and antisecretory agents. [ABSTRACT FROM AUTHOR]

Assefa Kebad Mengesha, Eshetie Melese Birru, Meaza Adugna Department of Pharmacology, College of Medicine and Health Sciences, University of Gondar, Gondar, EthiopiaCorrespondence: Assefa Kebad Mengesha, Email asielove23@gmail.comBackground: Traditionally, the root of Acacia seyal is used for the treatment of diarrhea. However, its efficacy has not been scientifically evaluated. Thus, this study aimed to validate the antidiarrheal activities using hydromethanolic crude extract and solvent fractions of Acacia seyal roots in mice.Methods: In each model, mice were divided into five groups of six mice at random. Group I mice (negative controls) were given 1mL/100 g distilled water for hydromethanolic crude extract tests as well as n-hexane, ethyl acetate and aqueous fractions, while groups II, III, and IV were given 100 mg/kg, 200 mg/kg, and 400 mg/kg of hydromethanolic crude extract or solvent fractions. Group V mice (positive control) were given 3 mg/kg Loperamide for the castor oil-induced diarrhea and enteropooling test. All of the doses were taken orally. However, Atropine sulfate, 5 mg/kg, was given intraperitoneally for the gastrointestinal motility test. Statistical Package for the Social Sciences (SPSS) version 26 was used to examine the statistical significance of differences in the number and weight of wet and total feces, distance traveled by a charcoal meal, and intestinal fluid accumulation across groups.Results: When compared to the vehicle-treated group, the crude extract and n-hexane fraction notably delayed the onset of diarrhea, reduced the weight and volume of intestinal contents, and hindered the intestinal transit at all tested doses (P < 0.001). The ethyl acetate fraction also significantly (P < 0.001) decreased the weight of intestinal content at all doses examined. Only at 400 mg/kg did the aqueous fraction statistically (P < 0.01) prolonged the onset of diarrhea and impeded gastrointestinal motility.Conclusion: According to this study, the hydromethanolic crude extract and solvent fractions of Acacia seyal roots have promising antidiarrheal effects.Keywords: antidiarrheal, Acacia seyal, castor oil, enteropooling, gastrointestinal motility

Viola canescens Wall. is an important medicinal plant with reported therapeutic benefits. The current work sought to investigate the antidiarrheal properties of V. canescens extracts both in vivo and in silico. This study applied molecular docking to unravel the molecular mechanism of V. canescens and to find the most effective phytocompounds with antidiarrheal effects. The antidiarrheal activity of V. canescens was assessed utilizing the castor oil-induced diarrhea assay and the charcoal meal assay. Antidiarrheal characteristics were evaluated by measuring parameters such as intestinal motility, fecal score, and hypersecretion. The V. canescens extract had a dose-dependent and statistically significant impact in the charcoal meal assay and castor oil-induced diarrhea assay. In the castor oil-induced diarrhea assay, the ethyl acetate fraction (65.96%) showed the highest percentage of defecation inhibition at the highest dose (300 mg/kg (bw)), followed by the uncorrected crystalline compound (63.83%), crude alkaloids (63.83%), chloroform fraction (63.83%), and crude flavonoids (55.32%), while the aqueous fraction (40.43%) and n-Hexane fraction (42.55%) revealed the lowest antidiarrheal potential. In addition, the molecular docking investigation showed emetine, quercetin, and violanthin, isolated chemicals of V. canescens, to have the highest binding affinity to the target μ and δ opioid receptors with significant inhibitory capacity. These pharmacologically active metabolites in V. canescens were effective in treating diarrhea. This study lends credence to the traditional usage of V. canescens in treating gastrointestinal disorders. [ABSTRACT FROM AUTHOR]

Objectives: Ginger (Zingiber officinale Roscoe) is a popular edible herb consumed and known globally for its culinary and medicinal properties. Particularly in South Asia, the ginger rhizome is used in several Gastrointestinal (GI) related ailments. In this study, we report preliminary findings on the GI relaxant activity of the dried variety of ginger rhizome. Materials and Methods: Ginger rhizome was soaked in 70% aqueous-methanol and dried to give the extract (Gd.Ex). Segments of different isolated smooth muscle preparations were suspended in tissue baths. Results: Phytochemistry profiling showed that the extract has terpenoids, phenols, and alkaloids. On baseline of isolated tissues like rat stomach pylorus, rabbit jejunum, guinea-pig ileum and colon, and rat uterus, Gd.Ex was devoid of any stimulant effect up to 10 mg/mL. The extract was able to completely inhibit spasmogenicity induced with K+ 80 mM in stomach pyloric strips, indicating a Ca2+ Channel Blocking (CCB) mechanism. Gd.Ex in bolus (1-10 mg/mL) and cumulative dosing (0.3-3 mg/mL), showed a relaxant effect on spontaneously contracting baseline of rabbit jejunum. The extract was then tested against different standard GI stimulants like acetylcholine (ACh, 0.3 µM), histamine (0.3 µM), and K+ (50 mM) in guinea-pig ileum. Gd.Ex (3 mg/mL) pretreatment abolished the stimulant responses. A similar inhibitory effect of the extract (0.3-1 mg/mL) was observed in guinea-pig colon and rat uterus against ACh. Conclusion: The study shows the spasmolytic potential of dried ginger extract in different smooth muscle preparations. Together with the earlier published results of dried ginger in rat stomach fundus, this explains the benefit of ginger in potentiating gastric emptying and alleviating nausea. [ABSTRACT FROM AUTHOR]

Methods: In vivo, 50 mice were divided into negative control, positive control (verapamil), low-, medium- and high-dose GFR (250, 500, 1,000 mg/kg) groups by a random number table, 10 mice in each group. The antidiarrheal activity was evaluated in castor oil-induced diarrhea mice model by evacuation index (EI). In vitro, the effects of GFR (0.01, 0.03, 0.1, 0.3, 1, 3, and 10 g/L) on the spontaneous contraction of isolated smooth muscle of rabbit jejunum and contraction of pretreated by Acetylcholine (ACh, 10 µmol/L) and KCl (60 mmol/L) were observed for 200 s. In addition, CaCl2 was accumulated to further study its mechanism after pretreating jejunal smooth muscle with GFR (1 and 3 g/L) or verapamil (0.03 and 0.1 µmol/L) in a Ca2+-free-high-K+ solution containing ethylene diamine tetraacetic acid (EDTA). Results: GFR (500 and 1,000 mg/kg) significantly reduced EI in castor oil-induced diarrhea model mice (P<0.01). Meanwhile, GFR (0.01, 0.03, 0.1, 0.3, 1, 3, and 10 g/L) inhibited the spontaneous contraction of rabbit jejunum (P<0.05 or P<0.01). Contraction of jejunums samples pretreated by ACh and KCl with 50% effective concentration (EC50) values was 1.05 (0.71–1.24), 0.34 (0.29–0.41) and 0.15 (0.11–0.20) g/L, respectively. In addition, GFR moved the concentration-effect curve of CaCl2 down to the right, showing a similar effect to verapamil. Conclusions: GFR can effectively against diarrhea and inhibit intestinal contraction, and these antidiarrheal effects may be based on blocking L-type Ca2+ channels and muscarinic receptors.

Introduction:Quercus L. genus (Oak) belongs to the family Fagaceae and their galls are used commercially in leather tanning, dyeing, and ink preparation. Several Quercus species were traditionally used to manage wound healing, acute diarrhea, hemorrhoid, and inflammatory diseases. The present study aims to investigate the phenolic content of the 80% aqueous methanol extract (AME) of Q. coccinea and Q. robur leaves as well as to assess their anti-diarrheal activity.Methods: Polyphenolic content of Q. coccinea and Q. robur AME were investigated using UHPLC/MS. The antidiarrheal potential of the obtained extracts was evaluated by conducting a castor oil-induced diarrhea in-vivo model.Result and Discussion: Twenty-five and twenty-six polyphenolic compounds were tentatively identified in Q. coccinea and Q. robur AME, respectively. The identified compounds are related to quercetin, kaempferol, isorhamnetin, and apigenin glycosides and their aglycones. In addition, hydrolyzable tannins, phenolic acid, phenyl propanoides derivatives, and cucurbitacin F were also identified in both species AME of Q. coccinea (250, 500, and 1000 mg/kg) exhibited a significant prolongation in the onset of diarrhea by 17.7 %, 42.6%, and 79.7% respectively while AME of Q. robur at the same doses significantly prolonged the onset of diarrhea by 38.6%, 77.3%, and 2.4 folds respectively as compared to the control. Moreover, the percentage of diarrheal inhibition of Q. coccinea was 23.8%, 28.57%, and 42,86% respectively, and for Q. robur 33.34%, 47.3%, and 57.14% respectively as compared to the control group. Both extracts significantly decreased the volume of intestinal fluid by 27%, 39.78%, and 50.1% for Q. coccinea respectively; and by 38.71%, 51.19%, and 60% for Q. robur respectively as compared to the control group. In addition, AME of Q. coccinea exhibited a peristaltic index of 53.48, 47.18, and 42.28 with significant inhibition of gastrointestinal transit by 18.98%, 28.53%, and 35.95 % respectively; while AME of Q. robur exhibited a peristaltic index of 47.71, 37, and 26.41 with significant inhibition of gastrointestinal transit by 27.72%, 43.89%, and 59.99% respectively as compared with the control group. Notably, Q. robur showed a better antidiarrheal effect in comparison with Q. coccinea and, the highest effect was observed for Q. robur at 1000 mg/kg as it was nonsignificant from the loperamide standard group in all measured parameters.

The leaves of Ficus lyrata warb (Moraceae) is used to treat GI disorder such as diarrhea in folklore use. The aim of present research is to explore the antidiarrheal and antipyretic activity of methanolic extract of leaves of F. lyrata. The diarrhea was induced by using castor oil. The anti-pyretic effects were also explored on yeast induced pyrexia. The physicochemical analysis of powder such as (total ash, water soluble ash, acid insoluble ash, moisture content, foaming index and swelling index) along with organoleptic evaluation of leaf of F. lyrata in order to access the quality Purity of the substance was also done. The phytochemical analysis of methanolic extract of F. lyrata leaves confirmed the presence of polyphenols, tannins, terpenoids, cardiac glycosides, flavonoids and reducing sugar. The antidiarrheal activity of MEFL at 100 and 200 mg/kg body weight showed 62% and 76% reduction in defecation respectively. The decrease in intestinal fluid accumulation at same dose revealed 67.2% and 75% reduction in fluid accumulation in intestine of Wister albino rats. The methanolic extract of F. lyrata showed reduction in distance travelled by charcoal meal such as 54% and 72% at dose 100 and 200 mg/kg respectively. The antipyretic effect at a dose of 100 and 200 mg/kg showed significant reduction in temperature. The anti-diarrheal activity of the F. lyrata might be due to the presence of flavonoids.

Background and aim: Secretory diarrhea is the most common type of diarrhea. This study aimed at exploring the possible mechanism of antisecretory action of Annona senegalensis stem bark and to identify the bioactive compounds. Experimental procedure: The ability of three crude extract; aqueous, dichloromethane and hexane stem bark extracts to inhibit castor oil-induced stooling in albino rats were assessed. Bioactivity guided fractionation of the most active extract was done using solvent-solvent partitioning (with hexane, dichloromethane, ethylacetate) and column chromatography. In vitro antioxidant activity of the most active sub-fraction was done using standard methods. The most active sub-fraction (25 mg/kg b. wt.) was administered to castor oil-induced diarrheal rats. Diarrheal rats small intestinal malondialdehyde concentration, antioxidant enzyme, cyclooxygenase II and Na+- K+ ATPase activities were determined using standard procedures. GC-MS analysis was done to identify the chemical compounds in the sub-fraction. Result and conclusion: Aqueous extract significantly decreased the number of wet stools. Sub-fraction 1 of ethylacetate fraction of aqueous stem bark extract (EFAS1) showed the highest stool inhibition. The H2O2 scavenging activity of EFAS1 was significantly greater than ascorbic acid. The sub-fraction significantly increased (p

Diarrhea is one type of disease with the most sufferers every year. Thus, it is considered an endemic disease in Indonesia and the potential disease of Extraordinary Events accompanied by mortality. One of the plants that can be used as a traditional medicine for diarrhea is the avocado seed, as it contains tannins, alkaloids, flavonoids, steroids and glycosides, which act as antidiarrheals. This study aims to determine the antidiarrheal effect of avocado seed extract suspension on mice induced by Oleum ricini and the optimum concentration of avocado seed extract suspension and capsules with an antidiarrheal effect in white male mice induced by Oleum ricini. The dosage forms chosen were suspension and capsules. This study used an experimental method with a test sample of the avocado seed. Avocado seed Simplicia was extracted by the percolation method, then an oral suspension and capsule formulation were made from the avocado seed methanol extract. It was evaluated and tested for its effectiveness with mice to cure diarrhea. Normal data were analyzed by One Way ANOVA and Post Hoc Tuckey Method. The results of this study showed that the administration of a suspension of avocado seed methanol extract at a dose of 800 mg/KgBB had the most optimum effect as an antidiarrheal against white male mice with a stool weight of 0.39 grams and a duration of diarrhea for 74 minutes. Furthermore, the administration of avocado seed extract capsules at a dose of 75 mg/KgBB had the most optimum effect as antidiarrheal against white male mice with Loperamide as a positive control. Therefore, it can be concluded that all suspension formulations and capsules of avocado seed methanol extract met the requirements for preparation evaluation. Suspension and avocado seed methanol extract capsules can cure diarrhea in white male mice.

Abstract Introduction The use of traditional medicinal plants in the management of diarrhea has long been practiced in Ethiopia. B. abyssinica fresen is one of the plants traditionally used to treat diarrhea whereas an in vivo study had not yet been conducted. Thus, this study aimed to evaluate the antidiarrheal activity of crude extract and solvent fractions of the leaf of B. abyssinica in mice. Methods Cold maceration within 80% methanol was used to extract the leaf powder and extract of the leaf was fractionated using n-hexane, chloroform, and distilled water. The in vivo antidiarrheal activity of crude extracts and solvent fractions were tested in experimental models of castor oil-induced diarrhea, enteropooling, and antimotility test. Five groups each with 6 mice were used under the three antidiarrheal models. Positive controls were treated with loperamide 3 mg/kg and atropine 5 mg/kg and 2% tween 80 was used in the treatment of negative controls. The extract and solvent fractions were administered at doses of 100, 200, and 400 mg/kg. Time of onset of diarrhea, number and weight of total and wet feces, the percent reduction in the number of wet feces, weight and volume of intestinal contents, and percent inhibition of intestinal motility were recorded. Data were analyzed using SPSS version 20. Result Defecation of castor oil-induced diarrheal or loose stools was inhibited (p

Diarrhea is a prevalent gastrointestinal problem associated with fatal implications. It is a huge public health concern that requires better alternatives to current drugs. This study investigated the mechanisms involved in the antidiarrheal activity of Anacardium occidentale (Ao) stem bark extract, a plant commonly used in the management of diarrhea in Nigeria. Methanolic stem bark extract of the plant was partitioned into three fractions: hexane fraction, ethyl acetate fraction (AoEF) and methanol fraction. In vitro studies on the effect of these fractions on guinea pig ileum (GPI) strips, as well as the modulatory effect of AoEF on standard agonists- and antagonists-induced GPI contraction and relaxation, revealed AoEF as the most active fraction. In vivo studies to assess the effect of AoEF on the dopaminergic, muscarinic, and serotonergic pathways were carried out using gastric emptying (GE) and gastrointestinal transit (GT) as experimental end points. AoEF was subjected to GC-MS analysis, while the identified compounds were docked with the muscarinic acetylcholine receptor M3 (CHRM3) using AutodockVina. Results indicated that AoEF inhibited GE and GT via inhibition of CHRM3. In addition, GC-MS analysis revealed the presence of 24 compounds in AoEF, while docking indicated that octadecanoic acid 2-(2-hydroxylethoxy) ethyl ester exhibited the highest binding affinity to CHRM3. This study indicated that the antidiarrheal activity of Ao is through its antimotility effect via the inhibition of the muscarinic pathway. And since none of the identified compounds exhibited higher binding affinity to CHRM3 relative to loperamide, the antimotility activity of these phytoconstituents may be via synergism.

A series of substituted benzimidazoles were synthesized by condensing o‐phenylenediamine with aromatic aldehydes in water using surfactants as catalyst. Mono and disubstituted benzimidazoles were formed preferentially with benzalkonium chloride and sodium dodecyl sulfate respectively. In silico molecular docking study revealed that 1‐(4‐chlorobenzyl)‐2‐(4‐chlorophenyl)‐1H‐benzo[d]imidazole bound strongly with delta, mu and kappa opioid receptors with binding scores of −9.4, −8.7 and −9.9 Kcal/mol respectively. This derivative also possessed highest binding (−9.0 Kcal/mol) against tubulin (binding score of albendazole was −6.4 Kcal/mol). The molecule also showed potential antibacterial activity with MIC50 ranging 16–128 μg/ml in in vitro antibacterial assay. Two benzimidazole derivatives showed powerful interaction with cyclooxygenase‐1 and cyclooxygenase‐2 (−8.1 and −8.9 Kcal/mol respectively) indicating their high analgesic and anti‐inflammatory potentials. All the compounds produced significant binding (−5.2 to −8.2 Kcal/mol) towards urate oxidase, glutathione reductase and peroxiredoxin. Monosubstituted derivative 4‐(1H‐benzo[d]imidazol‐2‐yl)phenol displayed superior binding (−6.5 Kcal/mol) with glucosamine 6‐phosphate synthase compared to ciprofloxacin (−6.3 Kcal/mol). In PASS analysis, monosubstituted derivatives demonstrated significant drug‐like potential (Pa>0.7). Hence, the synthesized benzimidazole derivatives can be used as potential leads for developing new drugs. [ABSTRACT FROM AUTHOR]

Extensive knowledge related to medicinal characteristics of plants by living in forest or semi-forest habitats and close observations of indigenous communities have led to the discoveries of the genus Lepisanthes and its traditional uses. The genus Lepisanthes is a member of the Sapindaceae family and is found in various regions of the world. Six species of Lepisanthes such as L. alata, L. amoena, L. fruticosa, L. senegalensis, L. rubiginosa, and L. tetraphylla are widely utilized in traditional and folk medicinal systems. They have been used for centuries for the treatment of ailments or symptoms such as pain, dizziness, high fever, frequent passing of watery stool (diarrhea), abscess, and healing of cuts and wounds. Various methodological approaches, mainly in vitro studies, have been employed to further explore the roles of the genus Lepisanthes. The studies identified that the genus Lepisanthes exerts beneficial effects such as antioxidant, antimicrobial, antihyperglycemic, antimalarial, analgesic, and antidiarrheal. However, the summary of the available literature remains inconclusive. This review aims to comprehensively address the botany, traditional uses, phytochemistry, methods, and pharmacological properties of the six commonly used Lepisanthes species. Hence, our review provides a scientific consensus that may be essential in translating the pharmacological properties of the genus Lepisanthes into future novel cost-effective medicines.

Wendlandia tinctoria var. grandis (Roxb.) DC. (Family: Rubiaceae) is a semi-evergreen shrub distributed over tropical and subtropical Asia. The present research intended to explore the pharmacological potential of the stem extract of W. tinctoria, focusing on the antioxidant, hypoglycemic, and antidiarrheal properties, and to isolate various secondary metabolites as mediators of such activities. A total of eight phenolic compounds were isolated from the dichloromethane soluble fraction of the stem extract of this plant, which were characterized by electrospray ionization (ESI) mass spectrometric and 1H NMR spectroscopic data as liquiritigenin (1), naringenin (2), apigenin (3), kaempferol (4), glabridin (5), ferulic acid (6), 4-hydroxybenzoic acid (7), and 4-hydroxybenzaldehyde (8). The dichloromethane soluble fraction exhibited the highest phenolic content (289.87 ± 0.47 mg of GAE/g of dried extract) and the highest scavenging activity (IC50 = 18.83 ± 0.07 µg/mL) against the DPPH free radical. All of the isolated compounds, except 4-hydroxybenzaldehyde, exerted a higher antioxidant effect (IC50 = 6.20 ± 0.10 to 16.11 ± 0.02 μg/mL) than the standard butylated hydroxytoluene (BHT) (IC50 = 17.09 ± 0.01 μg/mL). Significant hypoglycemic and antidiarrheal activities of the methanolic crude extract at both doses (200 mg/kg bw and 400 mg/kg bw) were observed in a time-dependent manner. Furthermore, the computational modeling study supported the current in vitro and in vivo findings, and the isolated constituents had a higher or comparable binding affinity for glutathione reductase and urase oxidase enzymes, glucose transporter 3 (GLUT 3), and kappa-opioid receptor, inferring potential antioxidant, hypoglycemic, and antidiarrheal properties, respectively. This is the first report of all of these phenolic compounds being isolated from this plant species and even the first demonstration of the plant stem extract's antioxidant, hypoglycemic, and antidiarrheal potentials. According to the current findings, the W. tinctoria stem could be a potential natural remedy for treating oxidative stress, hyperglycemia, and diarrhea. Nevertheless, further extensive investigation is crucial for thorough phytochemical screening and determining the precise mechanisms of action of the plant-derived bioactive metabolites against broad-spectrum molecular targets.

Xeromphis. uliginosa (Retz.) is an extinctive Bangladeshi medicinal plant that is locally used for the treatments of pain, diabetes, diarrhea, depressant, and other diseases. The present study was conducted to evaluate the peripheral analgesic activity (PAA), central analgesic activity (CAA), central nervous system antidepressant activity (CNS-AD), antidiarrheal activity (ADA), and hypoglycaemic activity (HGA) of methanolic root extract of X. uliginosa (MREXU) in a mice model. The acetic acid-induced writhing inhibition and tail flick method were applied to determine the PAA and CAA of MREXU. The CNS-AD was measured using the phenobarbitone sodium-mediated sleeping method whereas, the castor oil-induced antidiarrheal method was used to determine the ADA of the crude extracts. To determine the HGA of MREXU crude extract, the tail tipping technique was conducted in a mice model. The MREXU displayed potential PAA and CAA in mice models. The MREXU 200 and 400 mg/kg significantly inhibit the number of writings along with diclofenac sodium. On the other hand, MREXU both doses significantly inhibit thermal stimulus after 60 and 90 minutes respectively. In the CNS-AD study, crude extract of 200 and 400 mg/kg significantly increase the onset of sleep by decreasing the duration of sleep. Similarly, the dose of 200 mg/kg significantly reduced diarrheal faeces for the whole 4 hours of experiments. The heartiest outcome of MREXU was displayed in the HGA assay. Both doses of MREXU significantly reduced the blood sugar level for the entire 3 hours of the experiments. In this study, it is revealed that the root of MREXU has extremely significant blood sugar-reducing activity, potential CNSAD and mild to moderate nociceptive activity in the mice model.

Background: Traditional usage (typhoid, diarrhea, sore throat) and previously performed studies (antioxidative and anticancer activity) have asserted that Eurya acuminata has a widespread therapeutic potential. However, most of the pharmacological aspects of this plant are yet to be explored.Methods: Broth dilution method was selected to determine the minimum inhibitory concentration (MIC) of the plant extract. Antidiarrheal activity was figured out following the castor oil-induced diarrheal inhibition method. The oral glucose tolerance test (OGTT) was performed to assess antihyperglycemic activity. Alpha-glucosidase inhibitory assay was conducted according to the supplier's method. Acetic acid-induced writhing inhibition method was used to evaluate the peripheral analgesic activity.Results: HPLC analysis detected the presence of (-)-epicatechin, p-coumaric acid, trans-ferulic acid, rosmarinic acid, myricetin, and trans-cinnamic acid. In the broth dilution method, the extract exhibited MIC of 16 μg/ml against E. coli and S. aureus and 8 μg/ml against P. aeruginosa. In castor oil-induced antidiarrheal assay, E. acuminata extract significantly reduced 44.82% and 67.24% defecation, respectively at the doses of 250 and 500 mg/kg. Furthermore, in in vivo antihyperglycemic activity, E. acuminata extract reduced blood glucose levels to 6.8 mM and 4.68 mM, at the doses of 250 and 500 mg/kg, respectively at 60 min although the extract demonstrated no α-glucosidase enzyme inhibitory activity. Apart from that, in in vivo analgesic activity, the extract inhibited writhing reflexes dose-dependently, 15.16% and 37.13% at the doses of 250 and 500 mg/kg.Conclusion: This study shows that E. acuminata might be a good source to explore antidiarrheal, antihyperglycemic, and antimicrobial compounds for new drug development.

Mycobacteria are a unique group of microorganisms. They are characterised by exceptional adaptability and durability. They are capable of colonisation and survival even in very unfavourable conditions. In addition to the well-known obligate human pathogens, Mycobacterium tuberculosis and M. leprae, more than 200 other species have been described. Most of them form a natural part of the microflora of the external environment and thrive in aquatic and soil environments especially. For many of the mycobacterial species associated with human disease, their natural source has not yet been identified. From an ecological point of view, mycobacteria are saprophytes, and their application in human and animal diseases is opportunistic. Most cases of human disease from saprophytic mycobacteria occur in immunocompromised individuals. This adaptability and resilience to environmental pressures makes treatment of mycobacterial diseases (most often sapronoses and less often zoonoses) and permanent eradication of mycobacteria from the environment very difficult. Saprophytic mycobacterial diseases (sapronoses) are chronic and recurrent due to the fact of repeated endogenous or exogenous re-exposure. Therefore, knowledge regarding their occurrence in soil and dust would aid in the prevention of saprophytic mycobacterioses. In conjunction, their presence and ecological significance in the environment can be revealed. [ABSTRACT FROM AUTHOR]

Valeriana jatamansi Jones is a high-value perennial herb native to the Himalayas, and is distributed from Afghanistan to southwest China, India, Nepal, Bhutan, and Myanmar. The plant has a long history as a pharmaceutical, aromatic, and flavoring product. A previous systematic study has identified approximately 300 compounds with various activities in V. jatamansi. However, most studies have focused on its roots and rhizomes, and only a few studies have explored the medicinal potential of the leaves and whole plants. This study aimed to explore the antidiarrheal activity and metabolite profiles of V. jatamansi by examining different populations and plant organs. The metabolomics analysis, correlation analysis between antidiarrheal activity, and network pharmacological analysis revealed that samples of V. jatamansi showed activity in prolonging the onset time of diarrhea, regardless of population or organ. The fibrous root showed the strongest activity among all organs. No significant difference was observed among different populations regarding metabolite profiles, but 418, 411, and 389 metabolites were detected in the fibrous root, rhizome, and basal leaf of V. jatamansi , respectively. Next, the results of correlation analysis and network pharmacological analysis identified 13 metabolites, including five iridoids, one phenol carboxylic acid, one terpenoid, two phenols and phenolic acids, and four primary compounds. The mechanisms underlying the regulatory effects of these metabolites on diarrhea fall into two major categories, namely inflammation and protein phosphorylation. These results suggest that these 13 metabolites may contribute to antidiarrheal treatment by working synergistically. Collectively, this study identified potential antidiarrheal metabolites and effectively promoted the utilization of V. jatamansi. • The metabolite profiles of different organs were reported for the first time in this study. • All 70 % EtOH extracts of Valeriana jatamansi Jones showed strong antidiarrheal activity, showing substantial variation among organs instead of populations. • The fibrous root exerted strongest activity against diarrhea among organs. • The signaling pathways of the mechanism associated with V. jatamansi as an antidiarrheal agent were mainly enriched in inflammation and protein phosphorylation.

Dillenia pentagyna Roxb. is traditionally used to treat cancer, wound healing, diabetes, and diarrhea in local tribes. This study was designed to evaluate the pharmacological potentiality of this plant. In vivo analgesic, anti-inflammatory, and antipyretic studies of the methanol extracts of D. pentagyna (MEDP) leaves were performed by using acetic acid-induced nociception, formalin-induced paw licking, and yeast-induced pyrexia assay methods, respectively. In vivo antidiarrheal activity was carried out in mice by following castor oil-induced diarrhea and gastrointestinal transit manner. In vitro thrombolytic experiment was performed employing the clot lysis activity. Besides, a molecular docking study was performed by executing the software (PyRx, Discovery Studio, and UCSF Chimera). In the acetic acid-induced writhing study, MEDP possesses significant writhing inhibition in a dose-dependent manner. It showed 50.86% of maximum inhibition of pain in the case of MEDP at a dose of 400 mg/kg body weight. In the anti-inflammatory study, maximum inhibition rate was observed at a value of 59.98 and 41.29% in early and late phases, respectively, at the dose of 400 mg/kg body weight. In the case of yeast-induced hyperpyrexia, MEDP reduced hyperpyrexia in a dose-dependent manner. In the antidiarrheal assay, MEDP moderately inhibited the occurrence of diarrhea in all the experiments. In the thrombolytic study, a moderate (17.76%) clot lysis potency has been yielded by MEDP. Again, the molecular docking simulation revealed strong binding affinities with almost all the targeted proteins. The present study suggests that the MEDP possesses remarkable pharmacological activity and this finding validated the ethnobotanical significance of D. pentagyna as the source of pain, fever, and diarrhea management agent.

Anisomeles indica (L.) Kuntze is an ethnomedicinally important plant that has long been used in traditional medicine to treat a variety of ailments, including dyspepsia, abdominal pain, colic, allergies, inflammation, and rheumatic arthritis. However, the scientific framework underlying these medicinal properties is not well known. This study aimed to investigate the antidepressive, antidiarrheal, thrombolytic, and anti-inflammatory potential of a methanol extract of A. indica (MeOH-AI). The potential bioactive compounds in the MeOH-AI were identified using gas chromatography-mass spectrometry (GC-MS), and antidepressant activities were evaluated using the tail suspension test (TST) and forced swim test (FST). Antidiarrheal effects were also assayed in castor oil-induced diarrhea and gastrointestinal motility studies. The anti-inflammatory activities were explored by examining the effects on protein inhibition and denaturation in heat- and hypotonic solution-induced hemolysis assays. The thrombolytic activity was evaluated using the clot lysis test in human blood. BIOVIA and Schrödinger Maestro (v11.1) were applied for docking analysis to determine binding interactions, and the absorption, distribution, metabolisms, excretion/toxicity (ADME/T) properties of bioactive compounds were explored using a web-based method. The GC-MS analysis of MeOH-AI revealed the presence of several bioactive compounds. MeOH-AI administration resulted in significant (p

Viola canescens Wall. is an important medicinal plant with reported therapeutic benefits. The current work sought to investigate the antidiarrheal properties of V. canescens extracts both in vivo and in silico. This study applied molecular docking to unravel the molecular mechanism of V. canescens and to find the most effective phytocompounds with antidiarrheal effects. The antidiarrheal activity of V. canescens was assessed utilizing the castor oil-induced diarrhea assay and the charcoal meal assay. Antidiarrheal characteristics were evaluated by measuring parameters such as intestinal motility, fecal score, and hypersecretion. The V. canescens extract had a dose-dependent and statistically significant impact in the charcoal meal assay and castor oil-induced diarrhea assay. In the castor oil-induced diarrhea assay, the ethyl acetate fraction (65.96%) showed the highest percentage of defecation inhibition at the highest dose (300 mg/kg (bw)), followed by the uncorrected crystalline compound (63.83%), crude alkaloids (63.83%), chloroform fraction (63.83%), and crude flavonoids (55.32%), while the aqueous fraction (40.43%) and n-Hexane fraction (42.55%) revealed the lowest antidiarrheal potential. In addition, the molecular docking investigation showed emetine, quercetin, and violanthin, isolated chemicals of V. canescens, to have the highest binding affinity to the target μ and δ opioid receptors with significant inhibitory capacity. These pharmacologically active metabolites in V. canescens were effective in treating diarrhea. This study lends credence to the traditional usage of V. canescens in treating gastrointestinal disorders.

Phytobiotics are bioactive principles found in the roots, stems, leaves and fruits of plants and are supplied in the pig diet as essential oils, powders and extracts. These additives are used as food palatability improvers, they increase the secretory production of salivary glands, stomach juices, pancreatic enzymes and hepatic bile acids. They are also involved in the functioning of the enzymes of the intestinal mucosa and intestinal brush border, in gastric and intestinal motility, endocrine stimulation and in antioxidant and anti-inflammatory activity, as well as in intestinal health and productive performance. These compounds show bactericidal effects against Enterococcus faecalis, Clostridium spp., Staphylococcus aureus, Escherichia coli and Salmonella spp. Due to the action they exert on the cell membrane, they cause instabilities that compromise the osmotic balance and cause the lysis of the bacteria. In addition, they show immunomodulatory action, since they can act on T cells, B cells, NK cells (Natural Killer) and macrophages. For these reasons, different researchers are carried out internationally with the aim of evaluating the effect of phytobiotic additives on microbiological, immunological, histological, blood, productive and reproductive indicators in pigs. This review aims to assess the use of phytobiotic additives (essential oils, powders and extracts) in the different stages of pig production. Results of the bioactive components of essential oils, powders, plant extracts and production rates in the different pig categories are shown. [ABSTRACT FROM AUTHOR]

For in vivo study a 20 Albino rats were infected with pathogenic Escherichia coli to induce diarrhea, which then divided into four equal groups, the first one infected not treated, second group infected treated with aqueous solution of the Acacia nilotica gum at a dose 1g/kg. b.w., third group infected treated with ciprofloxacin 8mg/kg. b.w. while the last one infected treated with aqueous solution of the Acacia nilotica gum 1g/kg. b.w.+ ciprofloxacin 4 mg/kg.b.w., all treatments were twice daily and lasted for 7 days, after that, clinical signs, number of the watery stool body weight, electrolytes including Na+ and K+ were measured during the study. The results showed that the aqueous solution of the Acacia nilotica gum either alone or in combination with the half concentration of ciprofloxacin inhibited the tasted bacterium growth with zone of inhibition 11.60±0.24mm and 16.20±0.58mm respectively which they are significantly (P<0.05) less than the zone of inhibition that obtained by standard antibacterial ciprofloxacin 20.80±0.37mm. The in vivo results showed that the diarrhea continued to 8 days in the infected non treated group, 6 days in both groups that infected and treated with ciprofloxacin and aqueous solution of Acacia nilotica gum, while it was lasted to 5 days in infected group that treated with combination of ciprofloxacin + Acacia nilotica gum. The combination also decreased the reduction in body weight significantly as compared with group infected not treated and restored the electrolytes to their normal values at the ends of the experiment. In conclusion, the combination of ciprofloxacin + Acacia nilotica gum had antibacterial and antidiarrheal activity. [ABSTRACT FROM AUTHOR]

Scutellaria barbata (S. barbata), a traditional herbal medicine used in southern China, possesses antiinflammatory, antitumor, spasmolytic and expectorant effects. However, there are not many recent studies on its gastrointestinal effects. This study aimed to evaluate the antidiarrheal effect of the ethanol extract of S. barbata (SBE) and its effect on the isolated jejunum smooth muscle. Methods: The antidiarrheal effect of SBE (doses: 125, 250 and 500 mg/kg) on castor oil-induced diarrhea was investigated in vivo. The effect of SBE (0.01-10 mg/mL) on spontaneous or acetylcholine chloride (ACh, 10μM)/KCl (60mM)-induced contraction of isolated rabbit jejunum smooth muscle was examined in vitro. The possible spasmolytic mechanism of SBE (1 and 3mg/mL) was analyzed by accumulating CaCl2 in a Ca2+-free high-K+ (60mM) solution. Results: SBE (125, 250 and 500mg/kg) could delay the initial semi-solid onset time of mice and also reduce the diarrhea index in vivo. Furthermore, SBE (0.01-10mg/mL) could alleviate the spontaneous or ACh/KCl-induced contraction in vitro. SBE (1 and 3mg/mL) also inhibited the contraction induced by CaCl2, and the concentration–response curves of CaCl2 moved downward and to the right, similar to those of verapamil (0.01 and 0.1μM). Conclusions: SBE exerts antidiarrheal and spasmolytic effects, which provides a pharmacological basis for its use in functional gastrointestinal disorders. [ABSTRACT FROM AUTHOR]

Background: Cuscuta reflexa (dodder) belonging to the family Convolvulaceae has many ethno-medicinal uses such as antidiarrheal and antiemetic. This plant has been employed to treat diarrhea, where the antidiarrheal use of this plant is well established in different communities around the world without scientific bases. In addition, the antibacterial, anthelmintic, anticholinergic, and antihistaminic effects of this parasitic vine are partly responsible for the folkloric antidiarrheal use of this plant. In the present study, the antidiarrheal activity of C. reflexa was evaluated in pigeons (Columba livia) using the juice (JCR), aqueous (CRAE), and methanol (CRME) extracts. Methods: The antidiarrheal effect of C. reflexa was evaluated using different reported research models, with few modifications. In pigeons, diarrhea was induced by administration of castor oil (6 mL/kg, PO), ampicillin (250 mg/kg, IP), magnesium sulfate (2 gm/kg, PO), and cisplatin (6 mg/kg, IV). In these experiments, loperamide (2 mg/kg, IM) was used as a positive control, whereas JCR (1 mL/kg (1%) and 1 mL/kg (2%), CRAE (50, 100 and 200 mg/kg) and CRME (50, 100 and 200 mg/kg) were administered intramuscularly at different doses into each pigeon in the test groups. Results: In addition to cisplatin-induced diarrhea, all paradigms tested gave significant results (P < 0.01). The JCR, at different doses, exhibited a significant (p < 0.01) a dose-dependent antidiarrheal effect on both the frequency and the onset of diarrhea. Similarly, CRAE and CRME, at doses of 100 and 200 mg/kg, showed considerable (p < 0.001) inhibition against the onset and frequency of diarrhea. On the other hand, JCR, CRAE, and CRME exerted significant effects (p < 0.001) on the percentage inhibition (PI) of diarrhea and gastrointestinal charcoal transit in a dose-dependent manner. In this respect, the maximum PI (p < 0.01) of JCR, CRAE, and CRME in different experimental paradigms was 43.13, 49.14, and 55.99 %, respectively. Conclusions: Taken all together, results from this study reveal that the juice, aqueous, and methanol extract of C. reflexa exhibit significant anti-motility and anti-secretory potential. These findings may explain the medicinal use of C. reflexa in folk medicine as an antidiarrheal medicinal plant.
