This study aims to prove that administering BBLE as a natural antioxidant can prevent atherosclerosis by maintaining lipid profiles, antioxidant enzymes, and netrin-1 levels in hyperlipidemia in rat models. The research subjects were 20 adult male Wistar rats (Rattus norvegicus), which were divided into 2 groups using a randomized pretest and posttest control group design. Before treatment and after treatment for 3 months, lipid profiles, MDA, SOD, and netrin-1 were examined. The control group was only given high-cholesterol diets (HCD), while the treatment, apart from HCD, was also given BBLE 4mg/day. The data obtained was tested using paired t-test and group t-test. The results of the study showed that there was a significant decrease in netrin-1 in the control group (p<0.05) after being given HCD for three months. In the treatment group, it also decreased but it was not significant (p>0.05). Netrin-1 levels in the treatment group were higher than the control (p<0.05). The lipid profile experienced a significant increase in HDL in the treatment group accompanied by a significant decrease in MDA and an increase in SOD (p<0.05) when compared with the control group. This study concludes that administering BBLE at a dose of 4 mg/day to rats given HCD caused an increase in netrin-1 levels accompanied by improvements in lipid profiles and prevention of oxidative stress. The findings of this study reveal the novelty of BBLE in treating and maintaining blood vessel function in mice given HCD by increasing netrin-1 levels. [ABSTRACT FROM AUTHOR]

Chronic Kidney Disease (CKD) is a condition of gradual or chronic decline in kidney function, which is quite severe and caused by various kidney diseases, including urinary obstruction. This disease is progressive and generally irreversible. CKD requires kidney replacement therapy, one of which is continuous ambulatory peritoneal dialysis (CAPD). To determine the prevalence and risk factors for End Stage Renal Disease (ESRD) in patients undergoing CAPD due to urinary obstruction. We performed a retrospective cohort with a cross-sectional study was conducted using secondary data from medical record data of ESRD patients with CAPD accompanied by urinary obstruction at Dr. Saiful Anwar General Hospital, Malang, Indonesia. The prevalence of CKD in patients with CAPD accompanied by urinary obstruction was 6,50% and dominated by males (57,8%) with an age range of 41-50 years (26%). The majority of comorbidities are severely high the Body Mass Index (BMI) (89,0%) and hypertension (80,8%). The location of obstruction is mostly unilateral (5,64%) with mild levels (4,06%). Urinary obstruction is a frequent clinical finding in CKD patients with CAPD. The most common risk factor in this study was hypertension. The prevalence and comorbidities among CAPD patients with Urinary obstruction (UO) are better understood because to this study. It is necessary to recognise its limitations, particularly the small sample size and single-centre design. Future studies should involve more centres and larger patient groups in order to provide a more thorough knowledge of the mechanisms behind the high survival rates among CAPD patients.

Non-alcoholic fatty liver disease (NAFLD) is a condition marked by excessive fat accumulation in the liver and poses a significant health challenge. The leaves of Blumea balsamifera and Sargassum aquifolium have been reported to have anti-atherogenic effects. This study aims to determine the effectiveness of B. balsamifera extract (BBLE) and S. aquifolium extract (SAE) in preventing and treating liver fat accumulation in Wistar rats induced by a high-cholesterol diet through the expression of the AMP-activated protein kinase (AMPK)/ Sirtuin 1 (SIRT1)/peroxisome proliferator-activated receptor γ (PPARγ) pathway, and the leptin receptor. The experimental design of this study is laboratory-based, involving, 20 Wistar rats were fed a high-cholesterol diet over a period of 21 days. The rats were divided into four groups for the evaluation of BBLE and SAE effect: negative control (P0): induced with a high-cholesterol diet + distilled water, positive control (P1): induced with a high-cholesterol diet + simvastatin, P2: induced with a high-cholesterol diet + 4 mg/kg/bw BBLE, and P3: induced with a high-cholesterol diet + 4 mg/kg/bw BBLE and 4 mg/kg/bw SAE. The treatment duration extended over three months. Immunohistochemical analyses were performed on liver tissues to measure AMPK, SIRT1, PPARγ, and leptin receptor expression. The results indicated that leptin expression was lower in the BBLE+SAE group compared to the simvastatin group, and differences were significant between the BBLE and BBLE+SAE groups. No significant differences were noted in AMPK, SIRT1, and PPARγ expression between the simvastatin and BBLE+SAE groups (p≥0.05). In conclusion, BBLE and SAE effectively reduce liver lipid accumulation and enhance fat metabolism in hypercholesterolemic rats.

Blumea balsamifera (L.) DC., an important economic and medicinal herb, has a long history of being used as a traditional Chinese medicine. Its leaves have always been used as a raw material for the extraction of essential oils, comprising large amounts of terpenoids, which have good therapeutic effects on many diseases, such as eczema, bacterial infection, and hypertension. However, the genetic basis of terpenoid biosynthesis in this plant is virtually unknown on account of the lack of genomic data. Here, a combination of next-generation sequencing (NGS) and full-length transcriptome sequencing was applied to identify genes involved in terpenoid biosynthesis at five developmental stages. Then, the main components of essential oils in B. balsamifera were identified using GC–MS. Overall, 16 monoterpenoids and 20 sesquiterpenoids were identified and 333,860 CCS reads were generated, yielding 65,045 non-redundant transcripts. Among these highly accurate transcripts, 59,958 (92.18%) transcripts were successfully annotated using NR, eggNOG, Swissprot, KEGG, KOG, COG, Pfam, and GO databases. Finally, a total of 56 differently expressed genes (DEGs) involved in terpenoid biosynthesis were identified, including 38 terpenoid backbone genes and 18 TPSs, which provide a significant amount of genetic information for B. balsamifera. These results build a basis for resource protection, molecular breeding, and the metabolic engineering of this plant. [ABSTRACT FROM AUTHOR]

The essential oil, extracted from the Hmong medicine Blumea balsamifera (L.) DC. (BBO), is a purely natural wound repair agent. Its application has, however, been restricted due to its low solubility and high volatility properties. In this study, we have developed a nanoemulsion formulation to improve the characteristics of BBO. The particle size of the nanoemulsion was normally distributed, and 71% of its range was concentrated between 10-100 nm, with an average particle size of 62.8 nm and an encapsulation rate of 98%. After 7 days of application, the wound healing rate of the BBO nanoemulsion (BBO-NE) group was 1.5 times higher than that of the normal BBO group. Along with histological observations, nanoemulsion formulation has been demonstrated to significantly improve the efficacy of BBO for wound repair. In addition, inflammation-related TLR4, CD14 and IRAK-1 gene transcript levels were significantly reduced after the administration of BBO-NE compared to the BBO group, with downregulation of 47.8%, 35.7% and 57.8%, respectively, while the secretion of pro-inflammatory factors IL-6 and TNF-a was also significantly reduced by 83.8% and 32.7%, respectively, in the nanoformulation administration (BBO-NE) group compared to the BBO group. In contrast, the anti-inflammatory factor IL-10 was significantly increased by 4.2-fold. It was further found that the drug penetration per unit area increased significantly 6.30% to 19.5% at different time points after the application of the BBO-NE compared to the BBO. In conclusion, nano-formulation enhanced the drug penetration of the BBO, reduced inflammatory factors, increased the level of anti-inflammatory factors, and promoted collagen deposition, thereby accelerating wound repair.

Blumea balsamifera (L.) DC., a perennial herb in the Asteraceae family native to China and Southeast Asia, has a notable history of medicinal use due to its pharmacological properties. Using UPLC–Q–Orbitrap HRMS techniques, we systematically investigated the chemical constituents of this plant. A total of 31 constituents were identified, of which 14 were flavonoid compounds. Significantly, 18 of these compounds were identified in B. balsamifera for the first time. Furthermore, the mass spectrometry fragmentation patterns of significant chemical constituents identified in B. balsamifera were analyzed, providing important insights into their structural characteristics. The in vitro antioxidative potential of the methanol extract of B. balsamifera was assessed using DPPH and ABTS free-radical-scavenging assays, total antioxidative capacity, and reducing power. The antioxidative activity exhibited a direct correlation with the mass concentration of the extract, with IC50 values of 105.1 ± 0.503 μg/mL and 12.49 ± 0.341 μg/mL for DPPH and ABTS, respectively. For total antioxidant capacity, the absorbance was 0.454 ± 0.009 at 400 μg/mL. In addition, the reducing power was 1.099 ± 0.03 at 2000 μg/mL. This study affirms that UPLC–Q–Orbitrap HRMS can effectively discern the chemical constituents in B. balsamifera, primarily its flavonoid compounds, and substantiates its antioxidative properties. This underscores its potential utility as a natural antioxidant in the food, pharmaceutical, and cosmetics sectors. This research provides a valuable theoretical basis and reference value for the comprehensive development and utilization of B. balsamifera and expands our understanding of this medicinally valuable plant.

Blumea balsamifera, a wooden plant belonging to the family Asteraceae, is a medicinal herb with anticancer, antiviral, and multiple pharmacological effects, which are believed to be caused by its essential oil. The essential oil from B. balsamifera is comprised of mono- and sesqui-terpenes as the majority. Unfortunately, this plant has been facing the challenge of resource shortage, which could be effectively alleviated by biological engineering. Therefore, the identification of key elements involved in the biosynthesis of active ingredients becomes an indispensable prerequisite. In this study, candidate genes encoding monoterpene synthase were screened by transcriptome sequencing combined with metabolomics profiling in the roots, stems, and leaves of B. balsamifera. Then, these candidates were successfully cloned and verified by heterologous expression and in vitro enzyme activity assays. As a result, six candidate BbTPS genes were isolated from B. balsamifera, of which three encoded single-product monoterpene synthases and one encoded a multi-product monoterpene synthase. Among them, BbTPS1, BbTPS3, and BbTPS4 could catalyze the formation of D-limonene, α-phellandrene, and L-borneol, respectively. Meanwhile, BbTPS5 functioned in catalyzing GPP into terpinol, β-phellandrene, β-myrcene, D-limonene, and 2-carene in vitro. In general, our results provided important elements for the synthetic biology of volatile terpenes in B. balsamifera, which laid a foundation for subsequent heterologous production of these terpenoids through metabolic engineering and increasing their yield, as well as promoting sustainable development and utilization of B. balsamifera.

Borneol is a precious monoterpenoid with two chiral structures, (-)-borneol and (+)-borneol. Bornyl diphosphate synthase is the key enzyme in the borneol biosynthesis pathway. Many (+)-bornyl diphosphate synthases have been reported, but no (-)-bornyl diphosphate synthases have been identified. Blumea balsamifera leaves are rich in borneol, almost all of which is (-)-borneol. In this study, we identified a high-efficiency (-)-bornyl diphosphate synthase (BbTPS3) from B. balsamifera that converts geranyl diphosphate (GPP) to (-)-bornyl diphosphate, which is then converted to (-)-borneol after dephosphorylation in vitro. BbTPS3 exhibited a Km value of 4.93 ± 1.38 μM for GPP, and the corresponding kcat value was 1.49 s−1. Multiple strategies were applied to obtain a high-yielding (-)-borneol producing yeast strain. A codon-optimized BbTPS3 protein was introduced into the GPP high-yield strain MD, and the resulting MD-B1 strain produced 1.24 mg·L-1 (-)-borneol. After truncating the N-terminus of BbTPS3 and adding a Kozak sequence, the (-)-borneol yield was further improved by 4-fold to 4.87 mg·L-1. Moreover, the (-)-borneol yield was improved by expressing the fusion protein module of ERG20F96W-N127W-YRSQI-t14-BbTPS3K2, resulting in a final yield of 12.68 mg·L-1 in shake flasks and 148.59 mg·L-1 in a 5-L bioreactor. This work is the first reported attempt to produce (-)-borneol by microbial fermentation.

Medicinal plants have been widely used in healthcare based on traditional knowledge. We investigated the antimicrobial activities and phytochemical contents of a plant known as Blumea balsamifera (B. balsamifera), which Sabah native people have used for health benefits. Methanolic extracts and fractions of the leaves of B. balsamifera were tested for their phytochemical contents and their antimicrobial activities against four Gram-negative and five Gram-positive strains of bacteria. The extracts of B. balsamifera showed antimicrobial activities against three Gram-positive, and one Gram-negative bacteria, with the zone of inhibition ranging from 7.8 mm±0.41 to 10.5 mm±0.71. Fraction CE.F7 exerted the broadest antimicrobial activity towards four Gram-positive or Gram-negative bacteria. The phytochemical constituents identified in the extracts were alkaloid, flavonoid, steroid, and cardiac glycosides. The plant extract demonstrated antimicrobial activities and contained multiple phytochemical constituents. Further investigations into potential antimicrobial agents containing promising fractions would validate the medicinal properties of B. balsamifera used in Sabah. [ABSTRACT FROM AUTHOR]

Blumea balsamifera is a famous Chinese Minority Medicine, which has a long history in Miao, Li, Zhuang, and other minority areas. In recent years, due to the influence of natural and human factors, the distribution area of B. balsamifera resources has a decreasing trend. Therefore, it is very important to analyze the suitability of B. balsamifera in China. Following three climate change scenarios (SSP1-2.6, SSP2-4.5, and SSP5-8.5) under 2050s and 2070s, geographic information technology (GIS) and maximum entropy model (MaxEnt) were used to simulate the ecological suitability of B. balsamifera. The contents of L-borneol and total flavonoids of B. balsamifera in different populations were determined by gas chromatography (GC) and ultraviolet spectrophotometry (UV). The results showed that the key environmental variables affecting the distribution of B. balsamifera were mean temperature of coldest quarter (6.18–26.57 ℃), precipitation of driest quarter (22.46–169.7 mm), annual precipitation (518.36–1845.29 mm), and temperature seasonality (291.31–878.87). Under current climate situation, the highly suitable habitat was mainly located western Guangxi, southern Yunnan, most of Hainan, southwestern Guizhou, southwestern Guangdong, southeastern Fujian, and western Taiwan, with a total area of 24.1 × 104 km2. The areas of the moderately and poorly suitable habitats were 27.57 × 104 km2 and 42.43 × 104 km2, respectively. Under the future climate change scenarios, the areas of the highly, moderately, and poorly suitable habitats of B. balsamifera showed a significant increasing trend, the geometric center of the total suitable habitats of B. balsamifera would move to the northeast. In recent years, the planting area of B. balsamifera has been reduced on a large scale in Guizhou, and its ex situ protection is imperative. By comparison, the content of L-borneol, total flavonoids and fresh leaf yield had no significant difference between Guizhou and Hainan (P > 0.05), which indicated that Hainan is one of the best choice for ex situ protection of B. balsamifera.

Indonesia's mindset has been focusing on the use of natural medicines, food, and healing practices widely recognized by the nation's culture. Traditional medicines and herbs used in traditional medicine can often lead to the discovery of drugs against certain diseases. The aim of this review was to study evidence-based data on the importance of Sembung plant, Blumea balsamifera, as a potential traditional medicine. The distribution, ethnopharmacology, secondary metabolites, and bioactivity against several diseases are focused in this review. Information and research related to Sembung plant were searched using the terms "B. balsamifera," "phytochemicals," and "pharmacological activity" on ResearchGate, Google Scholar, Science Direct, PubMed, and scientific information-based databases up to 2020. Several ethnomedical articles recommend B. balsamifera for the treatment of sinusitis, colic pain, cough, kidney stones, flu, or as a diuretic. This knowledge has already been applied in several countries in Southeast Asia. B. balsamifera has been reported to contain several phytochemicals both volatile (terpenoids, fatty acids, phenols, alcohol, aldehydes, ethers, ketones, pyridines, furans, and alkanes) and non-volatile (flavonoids, flavanones, and chalcones). Extracts and phytochemicals of B. balsamifera contain several biological capacities such as antioxidant, antimicrobial, antifungal, anti-inflammatory, hypolipidemic, anti-infertility, hepatoprotective activity, antidiabetic, gastroprotective, antitumor, anticancer, and immunomodulatory agent against Coronavirus disease-19 infection. This review provides essential data for the potential application of B. balsamifera as a nutraceutical or in future medicinal preparations.

Six new diterpenoids, blusamiferoids A–F (1–6), including four pimarane-type diterpenoids, one rosane-type diterpenoid (3), and one rearranged abietane-type diterpenoid (6), were isolated from the dry aerial parts of Blumea balsamifera. Their structures were characterized by spectroscopic and computational methods. In particular, the structures of 1 and 4 were confirmed by X-ray crystallography. Compounds 5 and 6 were found to dose-dependently inhibit the production of TNF-α, IL-6, and nitrite oxide, and compound 5 also downregulated NF-κB phosphorylation in lipopolysaccharide (LPS)-induced RAW 264.7 cells.

Blumea balsamifera (L.) DC is a medicinal plant widely used against various ailments throughout Asian and African cultures. The reported efficacy of B. balsamifera and its phytochemicals against respiratory disorders suggests that it can be a potential therapeutic against the coronavirus disease 2019 (COVID-19), which is also a respiratory disease. This potential was demonstrated through an in silico assessment utilizing B. balsamifera phytochemicals and targeting the severe acute respiratory syndrome-coronavirus-2 main protease (SARS-CoV-2 Mpro), an enzyme that plays an important role in the infection process by SARS-CoV-2. The general strategy implemented was termed phytochemical mining in tandem with virtual screening (PM-VS). Data gathering of B. balsamifera phytochemicals reported in the literature was first conducted (PM stage) followed by VS through automated molecular docking of multiple ligands. The present study obtained the most comprehensive phytochemical record and organization of B. balsamifera phytochemicals (a total of 331). Surprisingly, 113 of the unique phytochemicals were promising SARS-CoV-2 Mpro inhibitors, of which 12 were re-discovered antiviral drugs from the plant. The promising inhibitors also reveal interesting in silico drug absorption, distribution, metabolism, excretion, and toxicity (ADMET) properties. Further analysis of the promising phytochemicals and their interactions with SARS-CoV-2 Mpro hints at the phenylpropanoid moiety (Ph-C3-) as a potential pharmacophore of the target enzyme. This study illustrated the utility of PM-VS in the preliminary stages of drug discovery and development; however, further studies (e.g. exhaustive VS and definitive "ex silico" experiments) are needed to confirm the present finding.

Blumea balsamifera essential oils (BBEOs) and Magnolia sieboldii essential oils (MSEOs) have exhibited outstanding antioxidant, anti-bacterial and anti-inflammatory activities. However, their anti-photoaging ability is still unclear. In this study, the chemical compositions of BBEOs and MSEOs are firstly determined by GC-MS analysis, and then their anti-photoaging is evaluated via an ultraviolet radiation (UV-B) induced mice skin-injury model. A total of 35 and 33 components are identified from BBEOs and MSEOs, and their dominant compositions are caryophyllene (18.54%) and borneol (18.33%) in BBEOs, and β-elemene (29.10%), γ-terpinene (17.01%) and (E)-β-ocymene (11.69%) in MSEOs. According to the skin injury model, the application of BBEOs and MSEOs to mice skin can effectively inhibit skin photoaging by down-regulating the expression of inflammatory factors including TNF-α, IL-6 and IL-10. Clearly, both essential oils reveal the potential as additives in cosmetics for anti-photoaging. [ABSTRACT FROM AUTHOR]

Abstract Blumea balsamifera (L.) DC., a medicinal plant with high economic value in the Asteraceae family, is widely distributed in China and Southeast Asia. However, studies on the population structure or phylogenetic relationships with other related species are rare owing to the lack of genome information. In this study, through high-throughput sequencing, we found that the chloroplast genome of B. balsamifera was 151,170 bp in length, with a pair of inverted repeat regions (IRa and IRb) comprising 24,982 bp, a large single-copy (LSC) region comprising 82,740 bp, and a small single-copy (SSC) region comprising 18,466 bp. A total of 130 genes were identified in the chloroplast genome of B. balsamifera, including 85 protein-coding, 37 transfer RNA, and 8 ribosomal RNA genes; furthermore, sequence analysis identified 53 simple sequence repeats. Whole chloroplast genome comparison indicated that the inverted regions (IR) were more conserved than large single-copy and SSC regions. Phylogenetic analysis showed that B. balsamifera is closely related to Pluchea indica. Conclusively, the chloroplast genome of B. balsamifera was helpful for species identification and analysis of the genetic diversity and evolution in the genus Blumea and family Asteraceae.

Environment fluctuations can influence a plant's phytochemical profile via phenotypic plasticity. This adaptive response ensures a plant's survival under fluctuating growth conditions. However, the resulting plant extract composition becomes unpredictable, which is a problem for highly standardized medicinal applications. Here we demonstrate, for the first time, the feasibility of tracking the changes in the phytochemical profile based on real-time measurements of a few environment and extract-preparation variables. As a result, we predicted the chromatograms of Blumea balsamifera extracts through an imputation-augmented convolutional neural network, which uses the image-transformed temporal measurements of the variables. We developed a sensor network that collected data in a greenhouse and a training algorithm that concurrently generated a data representation of the implicit plant-environment interactions leading to the mutable chromatograms of leaf extracts. We anticipate the generic applicability of the method for any plant and recognize its potential for addressing the standardization problems in plant therapeutics.

The sample in this study were 16 adult male wistar rats (Rattus novergicus) aged 3-4 months with a body weight of 150-200 grams, which were equally and randomly divided into two groups, namely control group (hyperlipidaemia and sterile aquadest) and treatment group (hyperlipidaemia and sembung leaf extract). Hyperlipidaemia was induced with lard administration for 50 days. Data were analysed statistically using the Independent t-test. The results showed that the number of Leydig cells in the treatment group was higher than the control group with 68.13 ± 1.89 and 55.63 ± 1.92 cells respectively (P <0.05). In addition, the mean Leydig cell core diameter of the control group, 5.00 ± 0.34 µm, was smaller compared to the treatment group which was 5.80 ± 0.20 µm (P <0.05). It can be inferred that sembung leaf extract provides a protective effect against damage to Leydig cells due to hyperlipidaemia. [ABSTRACT FROM AUTHOR]

Six new diterpenoids, blusamiferoids A–F (1–6), including four pimarane-type diterpenoids, one rosane-type diterpenoid (3), and one rearranged abietane-type diterpenoid (6), were isolated from the dry aerial parts of Blumea balsamifera. Their structures were characterized by spectroscopic and computational methods. In particular, the structures of 1 and 4 were confirmed by X-ray crystallography. Compounds 5 and 6 were found to dose-dependently inhibit the production of TNF-α, IL-6, and nitrite oxide, and compound 5 also downregulated NF-κB phosphorylation in lipopolysaccharide (LPS)-induced RAW 264.7 cells.

Hypertrophic scars (HS) still remain an urgent challenge in the medical community. Traditional Chinese medicine (TCM) has unique advantages in the treatment of HS. However, due to the natural barrier of the skin, it is difficult for the natural active components of TCM to more effectively penetrate the skin and exert therapeutic effects. Therefore, the development of an efficient drug delivery system to facilitate enhanced transdermal absorption of TCM becomes imperative for its clinical application. In this study, we designed a compound Salvia miltiorrhiza - Blumea balsamifera nanoemulsion gel (CSB-NEG) and investigated its therapeutic effects on rabbit HS models. The prescription of CSB-NEG was optimized by single-factor, pseudoternary phase diagram, and central composite design experiments. The results showed that the average particle size and PDI of the optimized CSB-NE were 46.0 ± 0.2 nm and 0.222 ± 0.004, respectively, and the encapsulation efficiency of total phenolic acid was 93.37 ± 2.56%. CSB-NEG demonstrated excellent stability and skin permeation in vitro and displayed a significantly enhanced ability to inhibit scar formation compared to the CSB physical mixture in vivo . After 3 weeks of CSB-NEG treatment, the scar appeared to be flat, pink, and flexible. Furthermore, this treatment also resulted in a decrease in the levels of the collagen I/III ratio and TGF-β 1 and Smad2 proteins while simultaneously promoting the growth and remodeling of microvessels. These findings suggest that CSB-NEG has the potential to effectively address the barrier properties of the skin and provide therapeutic benefits for HS, offering a new perspective for the prevention and treatment of HS.

Ai pian, derived from Blumea balsamifera (L.) DC. has various medicinal effects and a complex composition. The goal of this study was to analyze the chemical composition of Ai pian by using samples from different regions to explore differences between the chemical composition and its blood composition from treated mice to clarify whether its efficacy is related to synergism of multiple components to provide references for rational quality control. Gas chromatography – mass spectrometry (GC-MS) was used to determine and compare chemical compositions of blank and Ai pian containing serum of mice after 30 min of oral administration of Ai pian of seven batches from Zhenfeng, Wangmo and Luodian Counties; Guizhou Province; and Tian'e County; and Guangxi Province. Sixteen to twenty-two compounds of Ai pian were identified, with fourteen common compounds including L-borneol, L-camphor, borneol acetate, L-linalool, α-gurjunene, and 3-t-butyl-1, 2-dimethoxybenzene. Four to seven compounds were identified as blood components of Ai pian, and L-borneol, L-camphor, and borneol acetate were common prototypes with relative compositions from 13.720 to 36.509%, 2.336 to 5.219%, and 0.401 to 1.188%, respectively. Methyl oleate was a common metabolic component with a relative concentration of 0.021 to 0.446%. The chemical composition and blood components of Ai pian were complex, and its efficacy was related to synergism between several components including L-borneol, L-camphor, and borneol acetate. Therefore, detecting multiple index components of Ai pian is essential for quality control. [ABSTRACT FROM AUTHOR]

Blumea balsamifera (L) DC, known in the Philippines as sambong, is an herb valued for its health benef its especially in the management of urolithiasis. Various phytochemicals, including flavonoids such as quercetin, have been determined in sambong leaves. A reversed-phase high-performance liquid chromatographic method (RP-HPLC) was developed for the quantitative determination of quercetin in the methanol extract of sambong leaves obtained from Leyte, Cotabato, and Nueva Ecija, Philippines. The methanol extracts of sambong were prepared by maceration followed by rotary evaporation. The solid phase extraction (SPE) for the sample cleanup involved the use of a C18 SPE packing, a 0.5-mL sample load (50 mg/mL solution), and elution with 4-mL of 80:20 Methanol:0.5% H3PO4. The HPLC conditions for the determination of quercetin involved the use of a C18 4.6-mm x 250-mm column maintained at 30°C, 254-nm UV detection, and a mobile phase composition of 25 parts methanol and 75 parts mixture of 0.5% H3PO4 and 0.2% triethylamine with a 1 mL/min flow rate in gradient elution. A good linearity at the concentration range of 3.72–124 μg/mL of quercetin standard (r2=0.9989) was observed with the limits of detection (LOD) and quantitation (LOQ) at 0.68 ng/mL and 2.28 ng/mL, respectively. The intra-day (n=5-) and inter-day (n=3) precision values were satisfactory (%RSD

Our continuous search for new nitric oxide (NO) inhibitory substances as anti-neuroinflammatory agents for AD resulted in the isolation of one new labdane diterpenoid and three new guaiane sesquiterpenoids, as well as ten known compounds from Blumea balsamifera . Their structures were elucidated by NMR spectroscopic data analysis and the time-dependent density functional theory (TDDFT) electronic circular dichroism (ECD) calculations. The anti-neuroinflammatory effects were examined by inhibiting NO release in LPS-induced murine microglial BV-2 cells. The possible mechanism of NO inhibition of some bioactive compounds was also investigated using molecular docking, which revealed the interactions of bioactive compounds with the iNOS protein.

Ainaxiang (Blumea balsamifera), also known as Sambong, is an important ancient medicinal herb in Southeast Asia. It is rich in volatile oil, and still widely used nowadays for skin wound healing and treatment of sore throats. We analyzed the volatile oil from Blumea balsamifera (BB oil) by gas chromatography-mass spectrometry (GC-MS). Forty one components, including l-borneol, were identified. Next, the damaging effects of BB oil diluted with olive oil on liver at different concentrations (100%, 50%, 20%), were evaluated, using both normal and wounded skin. Plasma ALT, AST, ALP and TBili were assessed, along with liver histopathology. The results showed that serum levels of liver toxicity markers in the high concentration groups (100% w/v) increased compared with control groups, whereas no significant changes was observed in histopathology of liver samples. In the wound groups, treatment with BB oil resulted in a decrease in serum toxicity index, compared with normal animal groups. This study confirms the safety of short term BB oil consumption, though high BB oil doses may lead to mild liver injury and this response might be weakened in the case of cutaneous wounds. These results are expected to be helpful for guiding appropriate therapeutic use of BB oil.

The main components of sambong (Blumea balsamifera) are listed in this article. The whole plant and its crude extracts, as well as its isolated constituents, display numerous biological activities, such as antitumor, hepatoprotective, superoxide radical scavenging, antioxidant, antimicrobial and anti-inflammation, anti-plasmodial, anti-tyrosinase, platelet aggregation, enhancing percutaneous penetration, wound healing, anti-obesity, along with disease and insect resistant activities. Although many experimental and biological studies have been carried out, some traditional uses such as rheumatism healing still need to be verified by scientific pharmacological studies, and further studies including phytochemical standardization and bioactivity authentication would be beneficial.

Blumea balsamifera (Ai-na-xiang) is used as an important plant source of natural borneol, which is widely used in the pharmaceutical industry. The aim of this study was to establish the methods based on near infrared (NIR) spectroscopy for determining the geographical origin of B. balsamifera, as well as developing a method for the quantitative rapid analysis of the active pharmaceutical ingredients (APIs). A total of 109 samples were collected from China in 2013 and arbitrarily divided into calibration and prediction sets using the Kennard-Stone algorithm. The l-borneol and total flavone contents of the samples were measured by gas chromatography and ultraviolet-visible spectroscopy, respectively. The NIR spectra were acquired using an integrating sphere and a partial least squares (PLS) model was built using the optimum wavelength regions, which were selected using a synergy interval partial least-squares (SiPLS) algorithm. The root mean square errors of prediction of the l-borneol and total flavone models were 0.0779 and 2.2694 mg/g, with R² of 0.9069 and 0.8013, respectively. A discriminant model to determine the geographical origin of B. balsamifera (Guizhou and Hainan) was also established using a partial least squares discriminant analysis method with an optimum pretreatment method. The prediction accuracy rate of the model was 100%. NIR spectroscopy can be used as a reliable and environmentally friendly method to determine the API and the origin of different B. balsamifera samples. [ABSTRACT FROM AUTHOR]

[Objectives] To study the variation in main chemical composition of Blumea balsamifera in different growth stages, and to provide a theoretical basis to determine appropriate harvest period. [Methods] The l-borneol of the plant was determined by gas chromatography (GC) with methyl salicylate as internal standard, and total flavonoids were determined by the Aluminum nitrate colorimetry method of Ultraviolet-Visible spectrophotometry. The analysis of variance was used for statistical analysis of the l-borneol and total flavonoids of B. balsamifera in different months and different plant age. [Results] There were differences in chemical ingredients of B. balsamifera in different months of the year. The content of l-borneol in October was the highest, but there was no significant difference from August to December in l-borneol content (P > 0.05 ). l-borneol content of B. balsamifera in three ages was the highest compared with other ages, and there was a significant difference with B. balsamifera in one year or less (P<0.05). Relatively speaking, total flavonoids in June, August and November were higher; total flavonoids content of B. balsamifera in two ages was the highest compared with other ages, and there was a significant difference with other ages ( P <0. 05 ). [Conclusions] If l-borneol is taken as an indicator, for extracting Aipan (l-borneol), it can be harvested from September to mid-December , but October is the best. And it can be harvested at least three years. If the content of total flavonoids is taken as an indicator, it should be harvested in November. And it can be harvested 2-3 years.

【Objective】The present paper aims to discuss the infection characteristics of Blumea balsamifera roots and correlations between soil factors and AM fungi of Blumea balsamifera. 【Method】 The AM fungi isolated from soil and Blumea balsamifera roots in Wairan and Tianfang Villages，Xingyi City were identified by the wet sieving decant-sucrose centrifugation method according to the species description and pictures provided by Vesicular-arbuscular Mycorrhiza Appraisal Handbook and International Arbuscular Mycorrhizal Fungi Conservation Center. 【Result】53 AM fungi species are isolated from soil and Blumea balsamifera roots in Wairan and Tianfang Villages and 33 species，18 species，1 species and 1 species belong to glomus，Acaulospora， Gigaspora and Scutellospora separately. 35 AM fungi species are isolated from soil and Blumea balsamifera roots in Wairan Village and 22 species and 13 species belong to glomus and Acaulospora respectively. The dominant genera is glomus in two sample plots. 【Conclusion】 There is an obvious difference in species distribution of AM fungi between two sample plots. AM fungi can form the arum-type AM with Blumea balsamifera roots symbiotically. The spore density of AM fungi in Autumn is obviously higher than in Summer but there is no significant difference in mycorrhizal infection rate between Autumn and Summer. The infection rate of AM fungi is positively related to soil pH significantly (r =0.549，1 <0.05). The spatial distribution and infection rate of AM fungi are related to soil environment closely.
