The production of indigo, primarily used by the denim industry, increases year by year, and is mainly of synthetic origin. The textile industry, on which its production depends, is responsible for 10% of greenhouse gases and 20% of water pollution. However, the source of this pigment/colorant, mainly based on petrochemistry, remains a key issue today. Extracting indigo from plants is becoming a popular answer and requires an understanding and evaluation of the entire process, from raw material to pigment recovery. In this study, the indigotin precursor, indoxyl, derived from the hydrolysis of O-glycosides biomass extracted in water, was oxidized to obtain the desired pigment. This step is the most sensitive, as variations have been observed during this phase. Consequently, the standardization of the oxidation process was established to determine the extract capacity to consistently produce the blue dye pigment. Partial hydrolysis of the O-glycosides, the indoxyl precursors, was identified as a factor causing this yield variability in the obtained extracts. Once the precursors were fully chemically hydrolyzed, plants harvested during summer and during a freezing period showed a similar capacity to produce indigotin, with values of 412 ± 25 ppm and 379 ± 0 ppm, respectively. This result showed that in freezing conditions, the enzymatic material was not available, resulting in the lack of indigotin formation. To address the use of oxidation in an alkaline medium, a spontaneous oxidation method was proposed. This method produced a purer indigotin pigment, with a 21.6% purity compared to 5.9% purity using air-mediated oxidation in an alkaline medium. [ABSTRACT FROM AUTHOR]

Background and Aim: Rice straw, a widely available agricultural byproduct globally, has significant potential as a basal diet for livestock. The major challenge lies in obtaining high-protein foliage that can be easily extracted using natural water rather than chemical solvents. This study aimed to assess the ability of distilled water to extract protein concentrate from Indigofera leaves (Indigofera zollingeriana Miq.) and to evaluate its effectiveness in enhancing rumen feed fermentation and digestibility in low-quality rice straw basal diets. Materials and Methods: The study was conducted in two experimental series. Experiment 1 was designed to explore the ability of distilled water to extract protein concentrate from fresh and dry Indigofera leaves by comparing it with the 0.1 N NaOH standard solvent. Experiment 2 focused on the in vitro digestibility of protein concentrates extracted from fresh Indigofera leaves based on optimal findings from experiment 1. Five treatments consisting of 0.5% and 1.0% protein concentrate and two extractants (distilled water and 0.1 N NaOH) were used to extract protein from Indigofera leaves. These extracts were then added to rice straw-based diets. Rice straw without supplements was used as a control. The treatments were arranged using a randomized complete design with five replicates. Results: The results of experiment 1 showed that distilled water was superior to 0.1 N NaOH for extracting protein concentrate from fresh Indigofera leaves, as revealed by higher dry matter, protein yield, total amino acids (AA), and total essential AA (EAA) production. For in vitro experiment 2, supplementation with distilled water-extracted protein concentrates successfully increased rumen fermentation and digestibility in rice straw basal diets, as indicated by higher gas production, total volatile fatty acid, and microbial protein levels compared with 0.1 N NaOH. Conclusion: Findings from this study confirm that Indigofera leaf protein concentrate offers a new alternative for enhancing rumen feed fermentation and the digestibility of low-quality rice straw diets. This study implies that it is an easy, costeffective, and environmentally friendly approach, particularly beneficial for smallholders, to extract protein concentrate from fresh Indigofera leaves using distilled water and use it to enhance the quality of rice straw for ruminant feed. The limitation of this study is that the Indigofera supplement was established using in vitro digestibility under controlled laboratory conditions, which does not reflect real rumen conditions. Therefore, further studies using in vivo digestibility in ruminant animals are required to confirm the ability of the protein extracted from indigofera to enhance rumen feed fermentation in low-protein basal diets.

This study is the first to report the foliar and stem epidermal micro-morphology of 13 taxa of Indigofera L. (Fabaceae) using light (LM) and scanning electron microscopy (SEM). The micro-morphological characteristics studied here are related to the epidermal cell shape, size, frequency, anticlinal wall pattern, and stomatal complex types, size, position, frequency, and index. The study revealed 19 major normal stomatal types with eight subtypes and seven major abnormal stomatal types with 13 subtypes. The stomatal index was lower on the abaxial leaf surface than on the adaxial surface. Notably, the adaxial surface of I. hochstetteri had the highest stomatal index (27.46%), while the abaxial surface of I. oblongifolia had the lowest (9.95%). The adaxial surface of I. hochstetteri also displayed the highest average stomatal frequency (38.67), while the adaxial surface of I. spinosa had the lowest average frequency (9.37). SEM analysis revealed that most leaves had slightly sunken to sunken stomata, while stem stomata were positioned at the same level as epidermal cells in most taxa. Indigofera's foliar and stem epidermal anatomy recommends their application as baseline data coupled with other taxonomic data for the delimitation and differentiation of closely related taxa in the genus. The study provides a comprehensive description, illustrations, images, and micrographs of the stomatal types, as well as a taxonomic key for distinguishing the studied taxa of Indigofera.

This study investigates the effect of different cutting types and planting media on the growth of Indigofera zollingeriana, a valuable forage crop. The research used a factorial randomized block design (2 x 2) with 40 experimental units. The treatments included two cutting sources--stem cuttings (A1) and shoot cuttings (A2)--and two planting media--natural soil (B1) and natural soil supplemented with liquid organic fertilizer from rabbit urine (B2). Growth parameters such as the number of leaves, plant height, and stem diameter were measured. The results indicate that cutting type significantly affects leaf production, with shoot cuttings (A2) producing a higher number of leaves than stem cuttings (A1) (P<0.05). However, the planting media and its interaction with the cutting type had no significant impact on plant height and stem diameter (P>0.05). These findings suggest that using shoot cuttings could enhance the propagation and growth of Indigofera zollingeriana for sustainable forage production. Further studies are recommended to explore the long-term effects of organic fertilizer on biomass yield. [ABSTRACT FROM AUTHOR]

Indigofera koreana is an endemic species to Korea, yet its phylogenetic position remains unresolved. In this study, we sequenced and analyzed plastid genomes (plastomes) to clarify the phylogenetic standing of I. koreana. We produced next-generation sequencing data for I. koreana and its close relative, Indigofera kirilowii. The plastomes of both species were successfully assembled, measuring 159,517 bp for I. kirilowii and 159,459 bp for I. koreana. Both species shared the same number of 128 intact genes and had identical 35.7% guanine–cytosine content. Phylogenetic analyses utilizing complete plastome and coding sequence–only data, along with 20 other Indigofera plastomes, were conducted to elucidate their evolutionary relationships. Our findings indicate that I. koreana forms a monophyletic group with Indigofera decora, Indigofera carlesii, and I. kirilowii, supported by maximum bootstrap values. Specifically, the phylogenetic tree derived from complete plastome data strongly suggests that I. koreana is most closely related to I. kirilowii. While these results are in line with previously suggested infra-generic classifications, they highlight the need for more comprehensive genomic studies to further unravel the evolutionary dynamics within the Indigofera genus, especially considering the role of polyploidization in species diversification.

Leaf extracts are known to be rich in phytoconstituent biomolecules, making them a valuable source of medicinal compounds. They also serve as both capping and reducing agents in nanoparticle fabrication. A reaction between CuSO4.5H2O aqueous solution and the Indigofera tinctoria leaf extract results in the formation of stable copper nanoparticles. Phytochemical screening of the Indigofera tinctoria leaf extract revealed the presence of various compounds including carbohydrates, terpenoids, phenol, tannins, flavonoids, saponins, and glycosides in the sample. The biosynthesized copper nanoparticles (CuNPs) were subsequently subjected to various forms of analysis. Techniques used included UV-visible (UV-vis) spectroscopy, Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy. An observable change in the color of solutions from pale to thick brown indicated the formation of CuNPs. Further confirmation came from UV-vis spectroscopy, which established the production of CuNPs at 500 nm. FTIR analysis revealed that the CuNPs were covered by organic residues. The particles ranged from 210 nm to 260 nm as indicated from the SEM analysis. [ABSTRACT FROM AUTHOR]

Background: Indigofera gerardiana (IG) is traditionally used for its medicinal properties, but scientific validation is limited. This study aimed to evaluate its pharmacological effects, specifically anti-inflammatory, analgesic, and antipyretic activities, using established animal models. Methods: This experimental study was conducted at the Pharmacology Department of Khyber Medical College and University, Peshawar between Feb 2022 and Aug 2023. The n-hexane fraction of IG was tested at concentrations of 100mg/kg, 150mg/kg, and 200mg/kg in in-vivo animal models. Anti-inflammatory effects were assessed with paw edema models in 30 rats, analgesic effects in 30 mice using writhing and hot plate tests, and antipyretic activity in 30 rabbits with yeast-induced fever. Data were analyzed using one-way ANOVA with Dunnett’s post hoc test. Results: The n-hexane fraction of IG showed a dose-dependent anti-inflammatory effect, reducing carrageenan-induced edema by 12.5% and histamine-induced edema by under 15% at 200 mg/kg i.p. after 3 hours. Analgesic activity was also dose-dependent, with pain inhibition in the acetic acid-induced writhing model of 16.9% at 100 mg/kg, 20.76% at 150 mg/kg, and 26.13% at 200 mg/kg. In the hot plate test, maximum pain inhibition occurred at 200 mg/kg after 90 minutes (p < 0.001). However, IG extract did not show significant antipyretic effects compared to paracetamol, which effectively reduced fever at all doses (p < 0.001). Conclusion: The study findings suggest that the n-hexane portion of IG exhibits significant anti-inflammatory and analgesic activities across various animal models while showing no substantial impact on yeast-induced pyrexia.

The present paper deals with a comprehensive enumeration of leguminous taxa found in Birbhum District of West Bengal, India. We recorded 140 species, one subspecies, and two varieties, representing 82 genera from 24 tribes under four subfamilies, viz., Cercidoideae (6 species in 2 genera belonging to 1 tribe), Detarioideae (3 species in 3 genera belonging to 3 tribes), Caesalpinioideae (43 species in 24 genera belonging to 5 tribes), and Papilionoideae (91 taxa including 88 species, 1 subspecies and 2 varieties in 53 genera belonging to 15 tribes). Herbs (59 taxa) were the largest group, followed by trees (39), climbers (23), and shrubs (22). Crotalaria and Indigofera (7 species each) emerged as the dominant genera, followed by Senna (6) and Bauhinia and Senegalia with five species each. In this district, the legumes are represented under 24 tribes, of which the Phaseoleae is the largest comprising 24 taxa, followed by Desmodieae (16) and Cassieae (12). Regarding endemics, Indigofera prostrata exclusive to West Bengal is recorded from Birbhum District, while Grona brachystachya, Hardwickia binata, Pterocarpus marsupium, and P. santalinus are endemic to India.

Indigo plant (Persicaria tinctoria (Aiton) Spach) has been utilized as a dye material with antioxidant activity. To increase polyphenol yield, alkaline water was used for the extraction of indigo leaves. Total polyphenol content and hydrophilic oxygen radical absorbance capacity value of the alkaline water extract were higher than those of the pure water extract, whereas its β-carotene bleaching inhibitory activity and 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity were lower. The predominant compound in the alkaline water extract was 3,5,4'-trihydroxy-6,7-methylenedioxyflavone (TMF)-3-O-β-D-glucopyranoside. β-Carotene bleaching inhibitory activity of TMF was higher than those of TMF-O-glycosides. TMF-3-O-β-D-glucopyranoside was hydrolyzed by β-glucosidase from rat small intestine most effectively among the TMF-O-glycosides. Our results showed that alkaline water extraction of indigo leaves is a useful method to increase the recovery of polyphenols, in which TMF-3-O-β-D-glucopyranoside is the predominant compound, which can be easily hydrolyzed in the small intestine to TMF with high antioxidant activity against lipid peroxidation.

The bioactive extracts of traditional medicinal plants are rich in polyphenols and help to rejuvenate skin. The study was designed to assess the skin rejuvenating effects of a stable cream enriched with 4% I. argentea (IaMe) extract. The quantity of polyphenols by spectrophotometric methods was TPC, 101.55 ± 0.03 mg GAE/g and total flavonoid content; 77.14 ± 0.13 mg QE/g, while HPLC-PDA revealed gallic acid; 4.91, chlorogenic acid 48.12, p-coumaric acid 0.43, and rutin 14.23 µg/g. The significant results of biological activities were observed as DPPH; 81.81% ± 0.05%, tyrosinase; 72% ± 0.23% compared to ascorbic acid (92.43% ± 0.03%), and kojic acid (78.80% ± 0.19%) respectively. Moreover, the promising sun protection effects Sun protection factor of extract (20.53) and formulation (10.59) were observed. The active cream formulation (w/o emulsion) was developed with liquid paraffin, beeswax, IaMe extract, and ABIL EM 90, which was stable for 90 days as shown by various stability parameters. The rheological results demonstrated the active formulation's non-Newtonian and pseudoplastic characteristics and nearly spherical globules by SEM. The IaMe loaded cream was further investigated on human trial subjects for skin rejuvenating effects and visualized in 3D skin images. Herein, the results were significant compared to placebo. IaMe formulation causes a substantial drop in skin melanin from -1.70% (2 weeks) to -10.8% (12 weeks). Furthermore, it showed a significant increase in skin moisture and elasticity index from 7.7% to 39.15% and 2%-30%, respectively. According to the findings, Indigofera argentea extract has promising bioactivities and skin rejuvenating properties, rationalizing the traditional use and encouraging its exploitation for effective and economical cosmeceuticals.

Indigo quality is determined by its indigotin content. Another quality indicator is colour. For an evaluation of species, indigo samples from Indigofera tinctoria, Indigofera suffruticosa, Indigofera arrecta, Persicaria tinctoria, Strobilanthes cusia and Wrightia laevis cultivated in Austria and China were visually classified and analysed spectrophotometrically and using a L*a*b* measuring device. In addition to a standardised hot-extraction method without lime, some samples were extracted simulating traditional methods at ambient temperatures using lime. The highest indigotin contents were achieved with Indigofera arrecta (55%, Austria) and Strobilanthes cusia (56%, China). There were no statistically significant differences between the indigo extraction yields of the species cultivated in Austria, but Indigofera arrecta and Persicaria tinctoria had statistically significantly higher indigotin extraction yields than Indigofera tinctoria and Indigofera suffruticosa. From the species extracted in China, Strobilanthes cusia showed higher values in all parameters than Indigofera tinctoria, Indigofera suffruticosa and Wrightia laevis. Compared with the standardised method, the method simulating local practice yielded more indigo but had a lower indigotin content; the indigotin extraction yields did not differ greatly. L*a*b* values enabled precise estimations of the indigotin content, making it an interesting option for quality control, as inexpensive, easy-to-handle L*a*b* measuring instruments have become available.

• Eleven new species are described. • New infraspecific combination created for I. pinnata. • All species illustrated in detailed photographic plates. • Conservation assessment and IUCN red list status is recommended for every species. Indigofera sect. Brachypodae DC. is a large group of approximately 40 species within the Cape Clade, mostly restricted to the Core Cape Region (CCR), with only two species extending eastwards to Grahamstown. This section has been subdivided into four subsections based primarily on morphological characters. Subsect. Brachypodae is the most diverse of the four subsections and is characterised by having sclerophyllous leaves, with a distinctly sunken midvein and (usually) revolute leaf margins. This group occurs almost exclusively within Fynbos, with a few species growing in coastal Strandveld vegetation. Revised here, nineteen species are recognized in this subsection, eleven of which are new to science. Additionally, a new infraspecific combination is created for I. pinnata following nomenclatural and identification confusion. All species are formally described here, with photographic plates of each and illustrations of corollas and calyces provided. Many of the new species were either unrecognised at the time of the last revision in Flora Capensis 2, or have only been discovered recently. Distribution maps and information regarding habitat preference, phenology, and ecology and recommended IUCN red list status of each species are also provided. [ABSTRACT FROM AUTHOR]

This research was done as a factorial experiment with 5 replications was carried out. The seeds were primed using putrescine at concentrations of 0 (hydropriming), 0.5, and 1 mM, and control were used as control. Salinity treatment was applied under normal, low, moderate and severe (0, 50, 100, and 150 mM NaCl, respectively) salinity stress. According to the findings, increasing salinity levels reduced germination percentage, (GP), germination rate, (GR), coefficient of velocity of germination, (CVG), seed weight vigour index, (SWVI), by 29, 66, 53 and 25%, respectively and seedling fresh weight, seedling dry weight, roots length and shoot length by 37, 14, 72 and 61%, respectively, while increasing mean germination time (MGT), percentage of dry matter, total soluble sugar (TSS), reactive oxygen species (ROS) and malondialdehyde (MDA) by 112, 53, 57,16 and 182%, respectively. When seeds were primed using putrescine reduced the effects of oxidative stress by reducing ROS and MDA levels by 11 and 47%, respectively compared to control and improved the GP, GR, CVG, SWVI, root length and shoot length by 31, 81, 67, 36, 27, 19%, and decreased MGT by 40%. Although seed priming using 1 mM putrescine was effective in some parameters, there was no significant difference when compared to 0.5 mM putrescine. As a result, seed priming indigo using 0.5 mM putrescine with increasing dry matter by 73% appears to be more practical and economical in terms of mitigating the negative effects of salinity stress.

Blue denim, a billion-dollar industry, is currently dyed with indigo in an unsustainable process requiring harsh reducing and alkaline chemicals. Forming indigo directly in the yarn through indican (indoxyl-β-glucoside) is a promising alternative route with mild conditions. Indican eliminates the requirement for reducing agent while still ending as indigo, the only known molecule yielding the unique hue of blue denim. However, a bulk source of indican is missing. Here, we employ enzyme and process engineering guided by techno-economic analyses to develop an economically viable drop-in indican synthesis technology. Rational engineering of PtUGT1, a glycosyltransferase from the indigo plant, alleviated the severe substrate inactivation observed with the wildtype enzyme at the titers needed for bulk production. We further describe a mild, light-driven dyeing process. Finally, we conduct techno-economic, social sustainability, and comparative life-cycle assessments. These indicate that the presented technologies have the potential to significantly reduce environmental impacts from blue denim dyeing with only a modest cost increase. Conventional blue denim dyeing has both environmental and health-related consequences. Here, Bidart et al. use enzyme engineering to develop a viable method for the bulk production of indican and demonstrate dying processes which could significantly reduce the negative consequences of this billion-dollar industry.

Climate change and other extinction facilitators have caused significant shifts in the distribution patterns of many species during the past few decades. Restoring and protecting lesser-known species may be more challenging without adequate biogeographical information. To address this knowledge gap, the current study set out to determine the global spatial distribution patterns of Indigofera oblongifolia (Forssk) a relatively lesser-known leguminous species. This was accomplished by utilizing three distinct bioclimatic temporal frames (current, 2050, and 2070) and four greenhouse gas scenarios (RCPs 2.6, 4.5, 6.0, and 8.5), in addition to non-climatic predictors such as global livestock population, human modification of terrestrial ecosystems, and global fertilizers application (nitrogen and phosphorus). Furthermore, we evaluate the degree of indigenousness using the geographical area, habitat suitability categories, and number of polygons. This research reveals that climatic predictors outperform non-climatic predictors in terms of improving model quality. Precipitation Seasonality is one of the most important factors influencing this species' optimum habitat suitability up to 150 mm for the current, 2050 RCP 8.5 and 2070-RCPs 2.6, 4.5, and 8.5. Our ellipsoid niche modelling extends the range of precipitation during the wettest quarter and maximum temperature during the warmest month to 637 mm and 26.5–31.80 degrees Celsius, respectively. India has a higher indigenous score in the optimal class than the African region. This findings suggest that the species in question tends to occupy contiguous regions in Africa, while in India, it is dispersed into several smaller meta-populations. [ABSTRACT FROM AUTHOR]

Currently, the use of natural indigo dye has been treated as an alternative to overcome the environmental pollution caused by synthetic indigo. Irrespective of the indigo dye source, it must be reduced to its soluble form by using reducing agents in a suitable alkaline environment. Herein, bio‐sugars such as glucose or fructose were used for this purpose. The results revealed that when fructose was used instead of glucose, colour strength (K/S) values increased. In this work, cotton was cationised with water‐soluble chitosan. Water‐soluble chitosan in a wide pH range extends the use of chitosan in textiles, which otherwise is limited due to its poor water solubility at pH above 6.0. Colour fastness washing test was conducted to evaluate the efficacy of cotton cationisation. The performance of cationised samples was around 30% higher in comparison to non‐cationised samples. Moreover, in this article we have focused on integrating materials and design. We propose a garment, using natural indigo‐dyed cotton and a zero‐waste modelling approach, as a sustainable fashion product. [ABSTRACT FROM AUTHOR]

Background: Multidrug-resistant bacterial strains cause several serious infections that can be fatal, such as Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumonia, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacteriaceae (often referred to as ESKAPE pathogens). Since ancient times, several indigenous medical systems in India have utilized diverse medicinal plants (approximately 80,000 species) as conventional treatments for a variety of illnesses. A member of the Fabaceae family, also referred to as "Himalayan indigo," Indigofera heterantha Wall, is well known for its therapeutic properties. Methods: The present study investigated the antibacterial, antifungal and antihelmintic properties of the roots, bark, leaves, and flowers of I. heterantha from the Kashmir Himalayas. The effectiveness of the extracts against bacteria, fungi, and earthworms. Three of the tested organisms for bacteria were ESKAPE pathogens, as they are responsible for creating fatal bacterial infections. The antifungal potency of I. heterantha aqueous and methanolic extracts was evaluated using the Agar Well Diffusion Assay. The antihelmintic activity was carried out on an adult Pheretima posthuma Indian earth worm, which shares physiological and anatomical similarities with human intestinal roundworm parasites. Results: The methanolic extracts of root and bark have shown prominent activity against all bacterial strains, whereas aqueous extracts of flower, root, and leaves have shown promising activity against Staphylococcus aureus. The aqueous extract demonstrated good activity against S. cerevisiae at a concentration of 200 mg/ml with a zone of inhibition of 16 mm, while the methanolic extract displayed comparable activity against the fungal strains. The remaining two strains, P. crysogenum and A. fumigatus, were only moderately active in response to the extracts. All the extracts have shown anthelmintic activity except aqueous flower. Conclusion: These results will pave the way for the bioassay-guided isolation of bioactive constituents that may act as hits for further development as potential antibacterial agents against drug-resistant microbial and helminthic infections.

• Taxonomic description of new and little known Indigofera species from South Africa. • Four new Indigofera species, one new variety and two little known species are described. • One established taxon is raised to specific status and described with a new name. • An earlier name is found which has priority over an established species name. • All taxa are associated with the Pondoland Centre of Endemism, ranging to surrounding floristic areas. This second paper describes and clarifies new and poorly known Indigofera species, belonging to sect. Pinnatae (E.Mey.) Harv., from the Pondoland Centre of Endemism and associated neighbouring areas in the Eastern Cape and KwaZulu-Natal provinces, South Africa. Five new species (one with two infraspecific taxa) are recognized: Indigofera abbottii Schrire and K.W.Grieve , I. hillburttii Schrire and K.W.Grieve , I. tysonii Schrire and K.W.Grieve , I. herrstreyi Schrire and K.W.Grieve var. herrstreyi and I. herrstreyi var. helodes K.W.Grieve and Schrire, and I. ngwenyana Schrire and K.W.Grieve. Descriptions are provided for the poorly known I. corniculata E.Mey. and I. gerrardiana Harv., taxa rarely taken up in the literature and both having been mostly synonymised under I. dregeana E.Mey. that occurs outside the area of the present study. The name I. tenuissima E.Mey. was found to be the earliest, correct, name for the widespread species I. longipes N.E.Br. ex Baker f., leaving the coastal Zululand taxon – currently named I. tenuissima E.Mey. – requiring further evaluation.

The leaf extract of Indigofera linnaei Ali, an Indian medicinal plant, was utilized in the synthesis of copper oxide nanoparticles (CuO-NPs). Green chemistry is a safe and cost-effective method for the synthesis of nanoparticles using plant extracts. The synthesis of CuO NPs was confirmed using ultraviolet–visible (UV-visible) spectrum λ-max data with two peaks at 269 and 337 nm. Different functional groups were identified using Fourier-transform infrared spectroscopy (FT-IR). X-ray diffraction (XRD) was used to confirm the crystalline structure of the CuO-nanoparticles. Scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) analyses were performed to examine the surface morphology and elemental composition of the biosynthesized CuO-NPs. Furthermore, the synthesized CuO-NPs exhibited antibacterial activity against Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, and Enterococcus faecalis. Additionally, they exhibited a good insecticidal effect on Culex quinquefasciatus larvae, with low LC50 55.716 µg/mL and LC90 123.657 µg/mL values. The CuO-NPs inhibited human breast cancer cells in a concentration-dependent manner, with an IC50 value of 63.13 µg/mL. [ABSTRACT FROM AUTHOR]

The waste from the use of synthetic dye in the textile industry leads to environmental concerns, causing serious human and animal health issues. Research on waste recycling efforts has been made. However, this process is still challenging and expensive. In this context, the development of natural dye and optimization of its extraction process have attracted attention recent attention. Indigofera plants are found in several genera and are excellent sources of dye, known as indigo dye. There are three main genera of indigo, Isatis spp., Persicaria tinctoria (Ait) Spach (Polygonum tinctorium Ait), and Indigofera spp. that are used to produce industrial Indigo. These can be used as a dye by clothing manufacturers. In addition to being a potential commercial crop in the near future, indigo is a legume and can be used to further diversify the existing cropping systems in the U.S. In the U.S. Southern Great Plains, this crop could be an alternative crop to diversify and sustain the cotton-based cropping system that is predominant in the region. However, little research has been conducted regarding the agronomics and genetics of this crop. Therefore, this paper will review the current status on the genetics and agronomics of the industrial Indigofera sp. [ABSTRACT FROM AUTHOR]

Indigofera jodhpurensis sp. nov. (Fabaceae), which grows in arid places and wasteland near the edge of Jodhpur in the direction of Pali, Rajasthan, India, is described. Although the species is similar to Indigofera cordifolia and I. jaisalmerica, it differs from these in having profusely hairy juvenile twigs, various types of trichomes on leaf surfaces, sub‐sessile flowers, straightened mucro at the tips of the leaves, and pods that are often single‐seeded but can also be bi‐seeded. The current communication includes a key to species, a comparative morphological analysis, and some photographs. [ABSTRACT FROM AUTHOR]

The aim of the present study is to investigate the ameliorative potential of the aqueous extract of Indigofera tinctoria (IT) in aging-induced inflammation and its associated cardiac hypertrophy and fibrosis. Young (3-month-old) and aged (24–26-month-old) male Wistar albino rats were grouped into young control, aged control, aged + IT, and young + IT. The animals in the supplementary groups received 200 mg/kg BWT of aqueous extract of IT orally once a day for 21 days. Aged animals showed prolonged QT interval and increased weight and volume of the heart with a thickening ventricular wall. Infiltration of leukocytes and increased cardiomyocyte diameter and decreased numerical density along with cardiomyocyte apoptosis and increased collagen accumulation were also seen in aged myocardium when compared to the young. The expression profile of various pro-inflammatory cytokines such as IL-6, IL-1β, TNF-α, NFκB, and iNOS was increased with a concomitant reduction in IL-10 expression in the aged compared to the young. In addition, a marked increase in ROS generation, TGF-β, and α-SMA levels is evident in the aged myocardium. These pathological changes were greatly reversed in aged animals supplemented with IT. Furthermore, the aged + IT group showed repression of pro-inflammatory markers with a subsequent increase in IL-10 expression. Contrarily, no marked changes were observed between young and young + IT groups. Taken together, it is concluded that the aqueous extract of Indigofera tinctoria suppresses cardiac fibrosis and hypertrophy by repressing the inflammation and its associated activation of TGFβ and myofibroblast conversion.

Purpose: Pediculosis capitis, commonly known as head lice infestation, represents a significant health 26 problem for school children worldwide. Repeated and long-term usages of highly toxic pediculicides have resulted in the development of increased levels of resistance and do not kill louse eggs. Alternative pediculicides, such as herbal products, have recently been proposed for the treatment of head lice infestation, thereby decreasing toxicity. Methods: This study analyzed the chemical composition of I. suffruticosa leaf extracts using GC–MS and evaluated the effects of Indigofera suffruticosa Mill. (I. suffruticosa) leaf extract on the mortality of head lice and their eggs. Results: The major five components of the tested oils identified were as follows: n-hexadecanoic acid, hexadecanoic acid, ethyl ester, oleic acid, (E)-9-octadecenoic acid ethyl ester, and linoleic acid ethyl ester. The effective pediculicide of the I. suffruticosa leaf extracts affected head lice in all stages (egg, nymph, and adults). The concentrations of I. suffruticosa leaf extracts at 500 mg/mL produced the highest effective ovicidal on egg with 96.6% unhatching and pediculicide on nymphs and adults with 96.7 ± 5.7% and 86.7 ± 5.7% mortality, respectively, at 60 min (LT50 value < 10 min). The analysis of the external structure of the adult-stage head lice by SEM examination revealed that dead lice exposed to I. suffruticosa leaf extract displayed damage to the outer smooth architecture and obstructed the respiratory spiracles. Conclusion: We may conclude that the application of I. suffruticosa leaf extract produces an effective herbal pediculicide capable of affecting all stages of head lice. [ABSTRACT FROM AUTHOR]

The nutritional value of sago pith is limited due to its low protein content, making it less suitable for poultry feed. To increase the benefit values of the sago pith, it is necessary to process it through fermentation. The current study aimed to determine the effects of substrate composition and fermentation time of fermented sago (Metroxylon sagu) pith (SP) and Indigofera (Indigofera zollingeriana) leaves (IL) mixture using Rhizopus oligosporus as an inoculum on crude protein, crude fat and crude fiber content of fermented SP and IL, nitrogen retention, crude fiber digestibility, and energy metabolism in broiler chickens. The study was performed on 30 broiler chickens, average weighing ± 1.5 kg at 6 weeks of age, along with SP, IL, and R. oligosporus. This experiment was conducted using a randomized design in a 3×3 factorial with three replications. Substrate composition, or factor A, was made up of A1 (80% SP + 20% IL), A2 (60% SP + 40% IL), and A3 (50% SP + 50% IL). Fermentation time as Factor B entailed B1 (2 days), B2 (3 days), and B3 (4 days). The findings demonstrated a significant interaction between the time of fermentation and the composition of the substrate in relation to crude protein content, nitrogen retention, crude fat, crude fiber digestibility, and energy metabolism. It can be concluded that the composition of substrate 50% SP and 50% IL with 3 days of fermentation yielded the best result, with crude protein at 25.45%, nitrogen retention at 59.72%, crude fat at 0.020%, crude fiber at 6.40%, crude fiber digestibility at 57.34%, and metabolic energy at 2658.44 kcal/kg.

BackgroundIndigo naturalis (IN) is an herbal medicine that has been used for ulcerative colitis with an unclear mechanism of action. Indigo and indirubin, its main constituents, are ligands of the aryl hydrocarbon receptor (AhR). We assessed the safety, efficacy, and colon AhR activity of IN given orally to patients with treatment-refractory ulcerative colitis. The role of AhR in IN benefit was further evaluated with an AhR antagonist in a murine colitis model.MethodsThis open-label, dose-escalation study sequentially treated 11 patients with ulcerative colitis with either IN 500 mg/day or 1.5 g/day for 8 weeks, followed by a 4-week non-treatment period. The primary efficacy endpoint was clinical response at week 8, assessed by total Mayo score. Secondary endpoints included clinical remission, Ulcerative Colitis Endoscopic Index of Severity, quality of life, and colon AhR activity measured by cytochrome P450 1A1 (CYP1A1) RNA expression.ResultsTen of 11 (91%) patients, including 8/9 (89%) with moderate-to-severe disease, achieved a clinical response. Among these 10 patients, all had failed treatment with 5-aminosalicylic acid, 8 patients with a tumour necrosis factor (TNF)-alpha inhibitor, and 6 patients with TNF-alpha inhibitor and vedolizumab. Five patients were corticosteroid dependent. Clinical response was observed in all five patients who had been recommended for colectomy. Three patients achieved clinical remission. All patients experienced improved endoscopic severity and quality of life. Four weeks after treatment completion, six patients had worsened partial Mayo scores. Four patients progressed to colectomy after study completion. Colon CYP1A1 RNA expression increased 12 557-fold at week 8 among six patients evaluated. No patient discontinued IN due to an adverse event. Concomitant administration of 3-methoxy-4-nitroflavone, an AhR antagonist, in a murine colitis model abrogated the benefit of IN.ConclusionIN is a potentially effective therapy for patients with treatment-refractory ulcerative colitis. This benefit is likely through AhR activation.Trial registration numberNCT02442960.

• Four species new to science are described. • Detailed photographic plates and distribution maps are included. • Conservation assessments are provided for all four species. Four new Indigofera species are described from the Greater Cape Floristic Region (GCFR). Indigofera barkeri is a new annual from the Richtersveld, with small flowers, 3.5–4.0 mm long, pinnately trifoliolate leaves and laterally flattened seeds. Indigofera dodii is endemic to the area around Cape Town, growing on granite and shaly slopes.

• Indigofera heterantha is an important medicinal shrub. • Melatonin is an important growth promoter that elicite production of secondary metabolites. • Adventitious roots conserve the plants by producing pharmacologically important secondary metabolites. • Melatonin enhances the effectiveness of AgNPs synthesis in in-vitro culture. Indigofera heterantha is a medicinal shrub of the family Fabaceae that naturally produces pharmaceutically important polyphenolics and at the verge of extinction due to ruthless exploitation. The adventitious roots provide bases for the conservation of endangered plants by decreasing pressure on their wild populations and help in the large-scale production of pharmacologically important secondary metabolites. The main objective of the current study was to establish a feasible protocol for adventitious roots and to investigate the effect of melatonin on the biosynthesis of biomass, secondary cell products, and greener synthesis of silver nanoparticles (AgNPs) for various biological activities. Melatonin is an important growth promoter and plays a key role in plant defense that can be used as elicitors for large-scale production of secondary metabolites. Different concentrations of melatonin revealed that 1.5 mg l−1 melatonin was effective for the biosynthesis of maximum biomass during log phases of growth kinetics. The same melatonin concentration enhanced total phenolics content (TPC; 68.28 mg/g-DW), total flavonoids content (TFC; 24.34 mg/g-DW), total phenolics production (TPP; 153.63 g l−1), total flavonoids production (TFP; 54.80 g l−1), antioxidant activity and total secondary metabolites in adventitious roots. The melatonin-treated roots (300 mM) were able to produce maximum biogenic AgNPs, characterized by UV–vis spectroscopy (UV), scanning electron microscope (SEM), Fourier transform infrared (FTIR), and X-ray diffraction (XRD) and were used for various biological activities. These NPs displayed maximum antimicrobial activities and further revealed that AgNPs and aqueous root extract displayed higher cytotoxic activities. The protocol developed here provides an alternative strategy for germplasm conservation and melatonin proved to be one of the best elicitors for different activities and has the potential of scaling up by various pharmaceutical industrial applications.

Ethnobotanical information indicates that Indigofera conferta is used in northern Nigeria for the management of poisonous snakebites and the methanol extract was previously reported to have antivenin activity. In this study, we report the isolation of an oxyprenylated bioactive secondary metabolite; 2',4'- dihydroxy-4-prenyloxychalcone from the chloroform fraction of the aerial parts of the plant's methanol extract and the in vivo evaluation of the compound against Naja nigricollis venom. The compound has demonstrated significant (p < 0.05) and dose-dependent antivenin activity against LD99Naja nigricollis venom. At a dose of 10 mg/kg, the compound protected 60% of the animals tested from death. The observed activity lends credence to the traditional use of the plant in the management of snake bites in northern Nigeria. The compound, 2',4'- dihydroxy-4-prenyloxychalcone, could also serve as a lead in the development of novel antisnake venom agents. [ABSTRACT FROM AUTHOR]

Proper feed optimization is vital for the health and growth of goats, with fodder quality being a central factor. This study evaluated the impact of feeding goats guinea grass mixed with various tree legumes on their growth and feed consumption. Nine upgraded goats were used for this research, divided equally among three treatment groups. Each treatment was repeated three times, with one goat per repetition. The experimental treatments included guinea grass paired with Gliricidia (T1), Indigofera (T2), or Ipil-ipil (T3). The results showed that the T2 (Guinea grass + Indigofera tinctoria) combination resulted in the highest feed intake at 29.94kg over five weeks, a finding significant with a p-value of 0.04. Nutrient analysis demonstrated a significant intake of crude protein for T2 with a p-value of 0.038. Moreover, T2 exhibited the most substantial total weight gain (3016.67g) and an average daily gain of 86.19g/day, with p-values of <0.001 and 0.013 respectively. In conclusion, the mix of Guinea grass and Indigofera tinctoria offers the best results in terms of feed intake and goat growth performance. [ABSTRACT FROM AUTHOR]

A proper planting system and efficient management are needed to cultivate forage effectively. Therefore, this research aimed to evaluate forage production and nutrient content of different elephant grass varieties grown with Indigofera in the intercropping system and were harvested at different intervals of defoliation. The research was conducted in the dry and rainy seasons using a randomized block design with 3 factors (2x2x2) and 4 replications. The first factor was two different elephant grass varieties consisting of cv. Pakchong and Taiwan, the second factor was the planting pattern, including intercropping and monoculture, while the third factor was harvesting age, comprising 50 days and 60 days. The results showed an interaction effect between grass varieties, planting patterns, and harvesting ages. Intercropping the Pakchong varieties with Indigofera and harvesting at 60 days produced the highest forage fresh weight and DM production, ADF as well as NDF contents and yields, CP yield, and the highest carrying capacity (p<0.05) according to DM intake. When harvested at 50 days, Indigofera increased the protein content of forage, but this effect did not occur when it was harvested at 60 days. Furthermore, nutrient yields were not affected by interactions of three factors in the rainy season (p>0.05), but in the dry season, the highest ash and CP yields were produced by the Pakchong variety intercropped with Indigofera and harvesting at 60 days. The highest ADF and NDF yields were obtained from the Taiwan varieties grown in monoculture and harvested at 60 days. Based on the results, it was concluded that the two varieties of elephant grass could be cultivated with Indigofera in the intercropping system and harvesting time of 60 days will produce the highest nutrient yield and carrying capacity.

Pollution in aquatic ecosystems by various pollutants has been a concern in recent decades because of the devastating effect posed on the stability between the receiving water bodies and the biodiversity therein. Indigofera tinctoria has been used in a variety of fields, including health and medicine, as well as industrial applications such as textiles. The impacts of I. tinctoria on freshwater fishes, as well as the mechanisms underlying the biological effects, are, however, sparse. The goal of the study was to see how I. tinctoria affected Nile Tilapia (O. niloticus) juveniles' oxidative stress response, biochemical indicators, DNA disintegration, and protein profile. For 21 days, 6 varying concentrations were applied to the fish, including a control. The biochemical parameters in the test fish revealed a considerable variation in a doseresponse manner. In I. tinctoria treated fish, the enzyme activity, when compared with control treatment, lipid peroxidation, DNA fragmentation, and oxidative stress all increased relative to the toxicant doses used. The protein profiling revealed a modification in the protein credentials in I. tinctoria-treated fish when compared to the control. As per the study, I. tinctoria is toxic to O. niloticus, particularly at higher doses. The results of this research could be applied to biomonitoring studies of I. tinctorial toxicity, particularly in industrial applications. [ABSTRACT FROM AUTHOR]

(Effect of substitution of indigofera leaves with papaya leaf silage and different types of packaging on the quality and physical properties of wafers) ABSTRACT. The aims of this study to determine the quality of physical (aroma, color, texture) and the properties of physical (compactness, density, moisture content) of wafers with substrate composition (substitution of indigofera leaves/IL with papaya leaf silage/PLS) and different packaging. The study used a factored completely randomized design (CRD) (4x4) with 3 replications. The H factor is the composition of the substrate (substitution of IL with PLS), namely, H1= PLS 0% + IL 30% H2= PLS 2% + IL 28%; H3= PLS 4% + IL 26%; H4 = PLS 6% + IL 24%; factor N is the type of packaging, N0 = no packaging; N1= plastic; N2= paper; N3 = gunny sack. Parameters measured were quality of physical (color, texture, aroma) and properties of physical (specific gravity, density and moisture content) of wafers. The results showed that the interaction between the type of packaging and the composition of the substrate (P0.01) affected the texture and aroma of wafers. Composition of substrate significantly (P0.01) affected the density and aroma of wafers. The type of packaging significantly (P0.01) affected the physical quality (aroma, color, texture) and physical properties (moisture content). Substitution of 28% IL with 2% PLS on wafers with gunny sack resulted in the best texture of wafer (coarse, dense and not slimy texture, score 3.44) and substitution of 24% DI with 6% SDP with gunny sack packaging with the best aroma of wafer (typical wafer aroma, score 3.46).
