Abstract
The strategy of aqueous two-phase flotation (ATPF) followed by preparative high performance liquid chromatography (prep-HPLC) was established and used for the separation of astragalin from Flaveria bidentis. In the ATPF, the effects of sublation solvent, solution pH, (NH4)2SO4 concentration in aqueous solution, cosolvent, N2 flow rate, flotation time and volumes of the PEG phase on the recovery of astragalin were investigated in detail, and the optimal conditions of ATPF were selected: 50 wt% PEG1000 ethanol solvent as the flotation solvent, pH 4, 350 g/L of (NH4)2SO4 concentration in 5 % ethanol aqueous phase, 40 mL/min of N2 flow rate, 30 min of flotation time, 10.0 mL of flotation solvent volume and twice. After ATPF enrichment, the flotation product was further purified by prep-HPLC. As determined by HPLC, the purity of astragalin was 98.8 %.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE LAGOTIS BRACHYSTACHYA Maxim is a traditional ethnic medicine commonly used in Tibet. In Tibetan medicine theory, Lagotis brachystachya is mainly used for the treatment of inflammatory related diseases. However, the active components and mechanism of the anti-inflammatory activity of Lagotis brachystachya are not clear. AIM OF THE STUDY The putative anti-inflammatory active compounds from Lagotis brachystachya Maxim and its anti-inflammation related mechanism involving in the TLR4/MyD88/NF-κB and NLRP3 signaling pathways were investigated. MATERIALS AND METHODS In this study, we investigated the anti-inflammatory activity and mechanism of 32 compounds extracted from Lagotis brachystachya in HepG2 and THP-1 cells using the alcohol-induced HepG2 cell injury model and the monosodium urate (MSU) combined with lipopolysaccharide (LPS)-induced THP-1 cell inflammation model. RESULTS The results found that six compounds, including Echinacoside, Quercetin, Homoplantaginin, Tricin-7-O-glucoside, Apigenin and Luteolin-7-O-beta-d-glucopyranoside, were shown to exhibit significant anti-inflammatory effects in both cell models. Furthermore, these compounds were shown to inhibit the TLR4/MyD88/NF-κB and NLRP3 signaling pathways and reduce the release of pro-inflammatory cytokines IL-1β, TNF-α, and IL-6 in both cell models. CONCLUSION These findings suggest that Echinacoside, Quercetin, Homoplantaginin, Tricin-7-O-glucoside, Apigenin and Luteolin-7-O-beta-d-glucopyranoside from Lagotis brachystachya have promising potential as natural anti-inflammatory agents for the treatment of inflammatory-related diseases. The discovery of bioactive compounds from this plant opens up possibilities for the development of novel treatments for inflammatory-related diseases, potentially providing alternative or adjunctive options to conventional therapies.

Abstract
To overcome the shortcomings of traditional extraction methods, such as long extraction time and low efficiency, and considering the low content and high complexity of total flavonoids in Artemisia absinthium L., in this experiment, we adopted ultrasound-assisted enzymatic hydrolysis to improve the yield of total flavonoids, and combined this with molecular docking and network pharmacology to predict its core constituent targets, so as to evaluate its antitumor activity. The content of total flavonoids in Artemisia absinthium L. reached 3.80 ± 0.13%, and the main components included Astragalin, Cynaroside, Ononin, Rutin, Kaempferol-3-O-rutinoside, Diosmetin, Isorhamnetin, and Luteolin. Cynaroside and Astragalin exert their cervical cancer inhibitory functions by regulating several signaling proteins (e.g., EGFR, STAT3, CCND1, IGFIR, ESR1). Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis showed that the anticancer activity of both compounds was associated with the ErbB signaling pathway and FoxO signaling pathway. MTT results showed that total flavonoids of Artemisia absinthium L. and its active components (Cynaroside and Astragalin) significantly inhibited the growth of HeLa cells in a concentration-dependent manner with IC50 of 396.0 ± 54.2 μg/mL and 449.0 ± 54.8 μg/mL, respectively. Furthermore, its active components can mediate apoptosis by inducing the accumulation of ROS.

Abstract
Diabetic kidney disease (DKD) is a common microvascular complication of diabetes mellitus, and oxidative stress and mitochondrial dysfunction play an important role in this process. It has been shown that aldose reductase (ALR2) catalyzes NADPH-dependent reduction of glucose to sorbitol, resulting in oxidative stress and mitochondrial dysfunction in diabetic patients. Astragalin (AG), a flavonoid extracted from Thesium chinense Turcz., shows an inhibitory activity on ALR2. In this study, we investigated the therapeutic effects of AG against renal injury in streptozocin (STZ)-induced diabetic mouse model. Diabetic mice were orally administered AG (5, 10 mg·kg-1·d-1) for 4 weeks. We showed that AG treatment greatly improved the proteinuria and ameliorated renal pathological damage without affecting the elevated blood glucose in diabetic mice. Furthermore, AG treatment significantly suppressed highly activated ALR2, and reduced oxidative stress in the kidney of diabetic mice and in high glucose and lipids-stimulated HK2 cells in vitro. We demonstrated that AG treatment modulated mitochondrial quality control and ameliorated apoptosis, boosting mitochondrial biogenesis, maintaining mitochondrial dynamic homeostasis, and improving energy metabolism disorder in vivo and in vitro. In high glucose and lipids-stimulated HK2 cells, we found that AG (20 μM) restored the phosphorylation level of AMPK, and upregulated the expression and transcriptional activity of PGC1α, whereas treatment with H2O2, blockade of AMPK with Compound C or knockdown of AMPKα with siRNA abolished the protective effect of AG on mitochondrial function, suggesting that antioxidant effects and activation of AMPK-dependent PGC1α pathway might be the molecular mechanisms underlying the protective effects of AG on mitochondrial quality control. We conclude that AG could be a promising drug candidate for the treatment of diabetic renal injury through activating AMPK.

Abstract
Introduction Biogenic silver nanoparticles (AgNPs) may be a feasible therapeutic option in the research and development towards selectively targeting specific cancers and microbial infections, lending a role in precision medicine. In-silico methods are a viable strategy to aid in drug discovery by identifying lead plant bioactive molecules for further wet lab and animal experiments. Methods Green synthesis of M-AgNPs was performed using the aqueous extract from the Malvaviscus arboreus leaves, characterized using UV spectroscopy, FTIR, TEM, DLS, and EDS. In addition, Ampicillin conjugated M-AgNPs were also synthesized. The cytotoxic potential of the M-AgNPs was evaluated using the MTT assay on MDA-MB 231, MCF10A, and HCT116 cancer cell lines. The antimicrobial effects were determined using the agar well diffusion assay on methicillin-resistant S. aureus (MRSA) and S. mutans, E. coli, and Klebsiella pneumoniae. Additionally, LC-MS was used to identify the phytometabolites, and in silico techniques were applied to determine the pharmacodynamic and pharmacokinetic profiles of the identified metabolites. Results Spherical M-AgNPs were successfully biosynthesized with a mean diameter of 21.8 nm and were active on all tested bacteria. Conjugation with ampicillin increased the susceptibility of the bacteria. These antibacterial effects were most predominant in Staphylococcus aureus (p < 0.0001). M-AgNPs had potent cytotoxic activity against the colon cancer cell line (IC50=29.5 μg/mL). In addition, four secondary metabolites were identified, Astragalin, 4-hydroxyphenyl acetic acid, Caffeic acid, and Vernolic acid. In silico studies identified Astragalin as the most active antibacterial and anti-cancer metabolite, binding strongly to the carbonic anhydrase IX enzyme with a comparatively higher number of residual interactions. Discussion Synthesis of green AgNPs presents a new opportunity in the field of precision medicine, the concept centered on the biochemical properties and biological effects of the functional groups present in the plant metabolites used for reduction and capping. M-AgNPs may be useful in treating colon carcinoma and MRSA infections. Astragalin appears to be the optimal and safe lead for further anti-cancer and anti-microbial drug development.

Abstract
Senile plaques composed of β-amyloid protein (Aβ) and neurofibrillary tangles (NFTs) composed of intracellular hyper-phosphorylated tau are major causes of cognitive impairment and neuronal damage in Alzheimer disease (AD). Astragalin (AST), a naturally-occurring flavonoid compound, was reported to have neuroprotective effects in the brain, but its effects in AD remain unknown. Herein, the learning and memory deficits were alleviated and neuronal damage in the hippocampus were inhibited after the senescence-accelerated mouse prone 8 (SAMP8) mouse were given AST (5 mg/kg or 10 mg/kg) daily by gavage for 2 months. Furthermore, AST reduced Aβ1-40 and Aβ1-42 deposition, decreased β-carboxyl-terminal fragment (β-CTF) protein level and tau hyper-phosphorylation, but increased α-CTF protein level and glycogen synthase kinase-3beta (GSK-3β) phosphorylation in hippocampus of SAMP8 mice. Meanwhile, the effects of AST on AD were also explored in vitro by treating primary neurons with amyloid-β1-42 oligomers (Aβ1-42O). Consistently, AST also alleviated amyloid-β1-42 oligomers (Aβ1-42O)-induced neuronal damage, amyloid plaques, and tau phosphorylation in vitro model. Of note, estrogen receptor (ER)α and ERβ expression in the hippocampus of SAMP8 mice and Aβ1-42O-treated neurons was significantly decreased but their levels were increased by AST. Moreover, in vivo and in vitro experiments revealed that ER antagonist, Fulvestrant, reversed the effects caused by AST. Altogether, our investigation indicates that AST may ameliorate cognitive deficits and AD-type pathologies in SAMP8 mice and Aβ1-42O-treated neurons through upregulating ERα and ERβ expression. Our findings indicate the value of AST as a potential reagent for AD treatment.

Abstract
BACKGROUND Breast cancer is the most aggressive malignant tumor with high morbidity and mortality. Astragalin, a flavonoid widely found in a variety of edible and medicinal plants, is recorded to possess multiple biological and pharmacological activities. However, its effect of anti-breast cancer has been unknown. METHODS Computational pharmacology was employed to explore the potential mechanism of anti-metastasis and anti-angiogenesis effects of Astragalin on breast cancer. The targets of Astragalin were obtained from TCMSP, Swiss Target Prediction, SEA, BATMAN-TCM, ChemMapper and STITCH databases, and targets of breast cancer were got from OMIM, GeneCards, and DisGeNET databases. Protein-protein interaction network (PPI), Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed to elucidate the interactions of these two groups of targets. Moreover, the anti-metastasis and anti-angiogenesis effects of Astragalin were validated by in vitro and in vivo experiments using wound healing assay, transwell migration and invasion assay, gelatin zymography assay, tube formation assay, and chick embryo chorioallantoic membrane model. RESULTS Computational pharmacology analysis indicated that the effects of Astragalin against breast cancer were mainly related to the regulation of the cell movement, migration, and angiogenesis, and taking AKT, ZEB1, VEGF, and MMP9 as the promising targets. Further experimental pharmacology indicated that Astragalin exerted anti-metastasis and anti-angiogenesis activities on breast cancer, and verified AKT, ZEB1, VEGF, and MMP9 as the key targets. CONCLUSION Astragalin suppresses the metastasis and angiogenesis of breast cancer, and AKT, ZEB1, VEGF, and MMP9 are the promising targets for Astragalin against breast cancer. Thus, Astragalin is a potential therapeutic agent for breast cancer.

Abstract
RATIONALE Neuroinflammation can be alleviated via M2 microglia polarization, which could promote the recovery of perimenopausal depression. Astragalin (AST) possesses anti-neuroinflammatory activity. However, the effects of AST on perimenopausal depression and the molecular mechanism in regulating microglia polarization remained unknown. OBJECTIVES The purpose was to investigate the effects of AST on mice with simulated perimenopausal depression through regulating microglia polarization. It was aimed to clarify the molecular mechanism related to the interleukin-4 receptor (IL-4R)/janus kinase (JAK) 1/signal transducer and activator of transcription (STAT) 6 signaling pathway. METHODS The ovariectomy (OVX)/chronic unpredictable mild stress (CUMS)-induced murine model of perimenopausal depression was established and treated with AST. Then the depression-like behaviors and cognitive ability of mice were examined. After that, we detected the markers of microglia polarization and its regulatory signals. In addition, lipopolysaccharides (LPS)/adenosine triphosphate (ATP)-induced inflammatory BV2 model were used to verify the potential molecular mechanism. RESULTS AST alleviated perimenopausal depression-like behaviors and memory deficits. AST alleviated microglia activation and increased Ki67-positive cells in dentate gyrus (DG). The viability of BV2 decreased by LPS/ATP was raised by AST. Moreover, both in vivo and in vitro, AST switched microglia from M1 phenotype caused by OVX/CUMS or LPS/ATP to M2 phenotype. The IL-4R/JAK1/STAT6 signaling was restored, and the levels of inducible nitric oxide synthase (iNOS), nuclear NF-KappaB-p65 were reduced by AST. Importantly, AST showed prevention against the ubiquitination modification and degradation of STAT6. CONCLUSIONS Our results revealed new insights into molecular mechanism associated with microglia polarization in the effect of AST on the mouse model of perimenopausal depression.

Abstract
Inhibition of adipogenesis is crucial and is a key area of research to develop antiobesity drugs. In this study, 3-O-glucoside of kaempferol (astragalin) was isolated from Moringa oleifera leaves and evaluated for its lipolytic and antiadipogenic activity in 3T3-L1 adipocytes. Astragalin has substantially reduced the triglycerides content and lipid accumulation in 3T3-L1 adipocytes and enhanced the glycerol release in a dose dependent manner. The assay for secreted adipocytokines confirmed that, astragalin at a concentration of 20 µg/mL significantly (p < .01) increased the secretion of adiponectin, but decreased leptin secretion in 3T3-L1 adipocytes. In molecular studies, both the mRNA expression and corresponding protein expression of PPAR-γ, C/EBP-α, FAS, and leptin genes were downregulated while that of adiponectin was upregulated in astragalin treated groups. Taken together, astragalin of M. oleifera promotes lipolysis, suppresses adipogenesis in 3T3-L1 adipocytes, and may be considered as an effective candidate to treat obesity aliments.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Actinidia chinensis Planch. (ACP) is a common traditional Chinese medicine, which is mostly used for cancer treatment clinically. Liver cancer is a refractory tumor with a high incidence. Although ACP has been reported in the treatment of liver cancer, its possible mechanism of action is little known. AIM OF STUDY The aim of this paper was to investigate the active components of ACP in the treatment of liver cancer and the related mechanisms by a network pharmacology approach. METHODS The active components of ACP and the corresponding targets were obtained from multiple databases. Cytoscape software and STRING database were used to build the "herb-component-target (H-C-T)" network and protein-protein interactions (PPI) network. The key components and targets were further predicted by the Cytohubba plug-in in Cytoscape. Then, experiments were carried out on HepG2 cell line and Huh7 cell line to verify the effects and related mechanisms of the key compounds in ACP. RESULTS 28 active components in ACP and 1299 related targets were screened out according to two indicators, oral bioavailability (OB) and drug-likeness (DL). The key compounds predicted include rutinum, astragalin, and L-epicatechin, and the main signaling pathways focus on apoptosis. Astragalin, a key compound in ACP, could inhibit the expression of Bcl-2, up-regulate the expression of Bax, cleaved caspase 3, cleaved caspase 8, and cleaved caspase 9, and regulate the apoptosis signaling pathway to inhibit the proliferation of liver cancer cells to play a therapeutic role in anti-liver cancer. CONCLUSIONS These results suggest that ACP can alleviate the progression of liver cancer through the mechanisms predicted by network pharmacology, and provide a basis for the further understanding of the application of ACP in anti-cancer.

Abstract
More than 40% of infertile men are diagnosed with oligoasthenozoospermia and the incidence is still rising, but the effective treatments are not been found until now. Astragalin, one of the main active ingredients in traditional Chinese medicine, may be effective in the treatment of oligoasthenozoospermia. This study investigated the pharmacological effects of astragalin for treatment of oligoasthenozoospermia in male mice, induced by cyclophosphamide (CTX). Male mice were intraperitoneally injected by CTX (50 mg/kg), and astragalin (30 mg/kg) was given via oral gavage once daily. RNA-seq analysis highlighted astragalin upregulated gene expression of anti-apoptosis (AKT1and BCL2-XL), cell proliferation (ETV1, MAPKAPK2, and RPS6KA5) and synthesis of testosterone (STAR, CYP11A1, and PRKACB), but downregulated gene expression of cell apoptosis (BAD, BCL-2, CASPASE9, and CASPASE3) in mouse testis. Astragalin also significantly reversed the reduction in body weight, reproductive organs index, and sperm parameters (sperm concentration, viability, and motility) induced by CTX, and restored testicular abnormal histopathologic morphology induced by CTX. Furthermore, astragalin dramatically rescued the gene expression related to spermatogenesis (AKT1, BCL-2, CASPASE9, CASPASE3, MAPKAPK2, RPS6KA5, STAR, and PRKACB), and increased the level of testosterone by improving related proteins (STAR, CYP11A1, PRKACB) for oligoasthenozoospermia induced by CTX. In conclusion, astragalin may be a potential beneficial agent for oligoasthenozoospermia by increasing the testosterone levels in testis.

Abstract
Cissus rotundifolia has been reported to possess various biological activities such as anti-diabetic, anti-fertility, anti-hyperlipidemic, anti-malarial, anti-osteoporotic, and anti-parasitic activities. Therefore in the present study, eleven selected constituents of Cissus rotundifolia which includes aconitic acid, astragalin, acteoside, aliospiroside A, beta amyrin, bergenin, formononetin, gallic acid, isovitexin, isoorientin, and isoquercitrin were studied on the docking behavior of human neutrophil elastase (HNE), matrix metalloproteinases (MMP 2 and MMP 9), and tyrosinase by using PatchDock method. Furthermore, molecular physicochemical, bioactivity score/drug-likeness, ADME (absorption, distribution, metabolism, and excretion), and toxicity analyses were also carried out using Molinspiration, Swiss ADME, and ProTox-II methods, respectively. The molecular physicochemical investigation showed that three ligands such as acteoside, aliospiroside A, and isoorientin have three violations for Lipinski's rule of five. Similarly, ADME analysis one ligand (formononetin) predicated to have high blood-brain barrier (BBB) permeability effect. The docking studies showed that isovitexin exhibited the highest atomic contact energy (-341.61 kcal/mol) for human neutrophil elastase (HNE), more over alliospiroside A has shown maximum atomic contact energy for both matrix metalloproteinases (MMP 2 [-618.00 kcal/mol] and MMP 9 [-634.73 kcal/mol]). Furthermore, isoquercitrin has exhibited the highest atomic contact energy (-145.70 kcal/mol) for tyrosinase. Thus, the present investigation outcome provides new knowledge in understanding eleven Cissus rotundifolia constituents as possible novel inhibitors against HNE, MMP 2, MMP 9, and tyrosinase.

Abstract
Gastric cancer is a common malignant cancer, which is one of the most affected cancers by PI3K/AKT signaling. Here, we investigated the anti-tumor role of Astragalin, a natural flavonoid compound, in gastric cancer and explored the underlying molecular mechanism. Three well-established gastric cancer cell lines and xenograft mouse model were used to examine the anti-tumor effect of Astragalin by using CCK-8, transwell assays, and Western blot. Tumor burden of xenograft mice with Astragalin administration was monitored and determined during and at end of the experiments. Astragalin could effectively inhibit cell viability of gastric cancer cells and possessed good anti-tumor activity in xenograft mice. In addition, astragalin induced the expression of apoptotic signaling proteins, suppressed the migration and invasion cancer cells, and inhibited the PI3K/AKT signaling pathway significantly. In contrast, epidermal growth factor stimulation was able to block the anti-tumor activity of Astragalin. In conclusion, astragalin exerts its anticancer activities through inhibiting PI3K/AKT signaling, which highlights its potential for the treatment of gastric cancer.

Abstract
Background/Aims Astragalin (kaempferol-3-O-β-D-glucoside) is a flavonoid isolated from the leaves of persimmon or Rosa agrestis. Astragalin exhibits various anti-inflammatory properties; however, little is known about its therapeutic potential for inflammatory bowel disease (IBD). This study aims to investigate the anti-inflammatory effect of astragalin via blockade of the nuclear factor κB (NF-κB) signaling pathway in human colonic epithelial cells and a murine colitis model. Methods HCT-116 and HT-29 human colonic epithelial cells were pretreated with astragalin and stimulated with tumor necrosis factor-α (TNF-α). Cell viability was assessed by the MTS assay. Real-time reverse transcription polymerase chain reaction was used to analyze the messenger RNA expression of the inflammatory cytokines interleukin (IL)-6 and IL-8. The effect of astragalin on the NF-κB pathway was evaluated by Western blot analysis of inhibitor of NF-κB alpha (IκBα) phosphorylation/degradation and by electrophoretic mobility shift assay. Dextran sulfate sodium (DSS)-induced acute murine colitis model was used for in vivo experiments. Results Astragalin strongly suppressed the expression of proinflammatory cytokines in human colonic epithelial cells in a dose-dependent manner. Western blot analysis showed that astragalin inhibited IκBα phosphorylation/degradation. Additionally, astragalin reduced the DNA binding activity of NF-κB. Astragalin alleviated colon shortening and improved the pathologic scores in DSS-induced acute murine colitis model. Furthermore, astragalin reduced the level of phosphorylated IκBα and decreased the production of the inflammatory cytokines IL-6, IL-8, and TNF-α in the DSS-treated colon mucosa. Conclusions Astragalin exerted an anti-inflammatory effect through NF-κB pathway inhibition and attenuated murine colitis. Astragalin is thus a potential therapeutic agent for IBD.

Abstract
With the ulcerative colitis (UC) incidence increasing worldwide, it is of great importance to prevent and treat UC. However, efficient treatment options for UC are relatively limited. Due to the potentially serious adverse effects of existing drugs, there is an increasing demand for alternative candidate resources derived from natural and functional foods. Astragalin (AG) is a type of anti-inflammatory flavonoid, with Moringa oleifera and Cassia alata being its main sources. In this study, we investigated the therapeutic effects of AG on mice with dextran sulfate sodium (DSS)-induced colitis. Our results suggested that AG treatment reduced weight loss and the disease activity index (DAI), prevented colon shortening and alleviated colonic tissue damage. AG treatment reduced the expression of pro-inflammatory cytokines and related mRNAs (such as TNF-α, IL-6, and IL-1β), inhibited colonic infiltration by macrophages and neutrophils, ameliorated metabolic endotoxemia, and improved intestinal mucosal barrier function (increased expression levels of mRNAs such as ZO-1, occludin, and Muc2). Western blot analysis revealed that AG downregulated the NF-κB signaling pathway. Moreover, AG treatment partially reversed the alterations in the gut microbiota in colitis mice, mainly by increasing the abundance of potentially beneficial bacteria (such as Ruminococcaceae) and decreasing the abundance of potentially harmful bacteria (such as Escherichia-Shigella). Ruminococcaceae and Enterobacteriaceae (Escherichia-Shigella) were thought to be the key groups affected by AG to improve UC. Therefore, AG might exert a good anti-UC effect through microbiota/LPS/TLR4/NF-kB-related pathways in mice. The results of this study reveal the anti-inflammatory effect and mechanism of AG and provide an important reference for studying the mechanisms of natural flavonoids involved in preventing inflammation-driven diseases.

Abstract
Astragalin is a flavonoid existed in several edible and medicinal plants and was recorded to have multiple biological and pharmacological significances. This work aimed to assess the possible protective effect of astragalin administration against oxidative tension, acute inflammation and histopathological deformations in a mouse paw edema model induced following intra sub-plantar injection of carrageenan. Thirty-six male Swiss mice were divided into four groups: control, carrageenan, astragalin (75 mg/kg) + carrageenan, and indomethacin (10 mg/kg) + carrageenan. Astragalin administration for five consecutive days to carrageenan injected mice showed a significant reduction in the development of paw in a time dependent effect, inhibited lipoperoxidation by-product, malondialdehyde and increased superoxide dismutase and catalase activities. Astragalin was found also to suppress the inflammatory signaling in the inflamed tissue as exhibited by the decreased myeloperoxidase activity along with the decreased protein and transcriptional level of pro-inflammatory cytokines including tumor necrosis factor-alpha, interleukin-1 beta and interleukin-6. Moreover, inducible nitric oxide synthase and cyclooxygenase-2 expressions and their products (nitric oxide and prostaglandin E2) were downregulated. Additionally, astragalin decreased monocyte chemoattractant protein-1 and nuclear factor kappa B expression in the inflamed paw tissue. The recorded findings provide evidences for the potential application of astragalin as a plant-derived remedy for the treatment of acute inflammation due to its promising antioxidant and anti-inflammatory activities along with its ameliorative impact against the histopathological changes in the paw tissue.

Abstract
Inflammation plays a key role in the pathogenesis of depression and antidepressant therapies. Astragalin (AST) is a bioactive flavonoid that possesses an anti-inflammatory property. However, the antidepressant action of astragalin has not been addressed. In this study, we explored the antidepressant effects of astragalin and its underlying mechanism. Our results showed that AST significantly improved the behavioral defects in chronic unpredictable mild stress (CUMS) model, promoted SIRT1 expression, and decreased the protein levels of NF-κB p65, NLRP3, cleaved capase-1, cleaved IL-1β and cleaved gasdermin D in the hippocampus. Immunohistochemistry revealed AST mitigated CUMS-induced microglia overactivation. In vitro, AST profoundly increased the cell viability in lipopolysaccharides (LPS) and adenosine triphosphate (ATP) treated BV2 cells, with upregulated SIRT1 expression and downregulated protein levels of nuclear NF-κB p65, NLRP3, cleaved capase-1, and cleaved gasdermin D. Declined cleavage of gasdermin D was observed after AST administration in immunocytochemistry. Nevertheless, the in vivo and in vitro effects of AST were compromised by SIRT1 inhibitor EX-527. These results indicated that AST possessed an antidepressant property, which was dependent on SIRT1 signaling modulated NLRP3 inflammasome deactivation.

Abstract
BACKGROUND Astragalin (AG), a flavonoid from many traditional herbs and medicinal plants, has been described to exhibit in vitro anti-inflammatory activity. The paper aimed to study the effects of astragalin on anti-inflammatory, anti-oxidative ability and apoptosis signaling pathway in brain tissue of rats with cerebral ischemia-reperfusion injury, and to explore its possible mechanism. METHODS The rat model of focal cerebral ischemia-reperfusion injury was established by suture method. It was randomly divided into 5 groups, sham operation group, ischemia-reperfusion (I/R) treatment group, and astragalin treatment I / R group (12.5, 25, 50 mg / kg). After 24 h of reperfusion, the neurological deficits of the rats were analyzed and HE staining was performed. The volume of cerebral infarction was calculated by triphenyltetrazolium chloride (TTC) staining, and the apoptosis of nerve cells was detected by TUNEL staining. In addition, the content of malondialdehyde (MDA), nitric oxide (NO), superoxide dismutase (SOD), glutathione (GSH) assay and glutathione peroxidase (GSH-Px) were measured in rat brain tissue. Western blot analysis was used to determine the expression of related proteins. RESULTS Compared with I/R group, the neurological deficit score and infarct volume of I/R rats were reduced in the astragalin treatment group. In the astragalin treatment group, MDA and NO levels in I/R rats were reduced, antioxidant enzymes and superoxide dismutase (SOD) activity were increased. In the astragalin treatment group, NF-κB (p65) and cyclooxygenase-2 (COX-2) expression levels were down-regulated, NF-E2-related factor 2 (Nrf2) nucleus and heme oxygenase-1 (HO-1) protein expression levels were up-regulated. In addition, the astragalin treatment can inhibit apoptosis, down-regulate Bax and cleaved caspase-3 expression, up-regulate Bcl-Xl expression. CONCLUSION The antioxidant properties of astragalin may play an important role in improving cerebral ischemia-reperfusion injury.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cedrela serrata Royle (C. serrata) is a medicinal plant not only used for constructions but also an important conventional medicine for the treatment of various diseases such as; diabetes, jaundice, liver diseases, diarrhea, fever, chronic infantile dysentery, intestinal worms, hypertension, skin and blood diseases. AIMS This review article documents and critically assesses, for the first time; up to date categorized information about C. serrata including its reported pharmacological activities, cultural uses, active compounds, and botanical description. MATERIALS AND METHOD s: All provided information about C. serrata was collected using the electronic databases (e.g. Google Scholar, Web of Science, Scopus, PubMed, Science Direct and Springer Link), books (e.g. Trees of Pakistan and Herbalism, Phytochemistry, and Ethnopharmacology) and thesis. RESULTS Qualitative and quantitative phytochemical studies on C. serrata revealed the presence of important chemical constituents such as; flavonoids, phenolic acids, alkaloids, saponins, tannins, and cardiac glycosides. The phytochemicals showed various in vitro activities like antioxidant, anti-infective, antiglycation, cytotoxic activities. Major areas of research conducted on C. serrata are its antioxidant and anti-infective activities. Few historical uses of C. serrata are supported by modern in vitro pharmacological studies such as; antidiarrheal, antidiabetic, and leishmanicidal activity. CONCLUSION There were convincing evidence in in vitro studies supporting C. serrata antioxidant, anti-infective, anti-diabetic, anti-glycating, and cytotoxic activities. Nevertheless, all reported pharmacological activities were carried out in vitro and a gap in research i.e. preclinical and clinical investigation still exists. The authors emphasize the need for future in-depth research and clinical trials to investigate C. serrata pharmacological activity, clinical efficacy and safety. The potential chemical compounds with suggestive classes may need to be isolated and pharmacological activities must be established for these compounds. The plant has very limited information about pharmacological activities and the data available for supportive cultural uses needs proper validation.

Abstract
Astragalin, isolated from flowers of Rosa chinensis Jacq., is a kind of flavonoid, with anti-inflammatory, antioxidant, antiviral, analgesic, antibacterial, antiallergic, and antihepatotoxic effects. However, no studieson the procoagulant effect of astragalin have been reported. This study aimed to investigate the procoagulant activity of astragalin and its mechanism. Its procoagulant effect was investigated by activated partial thromboplastin time (APTT), thrombin time (TT), prothrombin time (PT), and fibrinogen (FIB) in vitro, and a rat model established by heparin sodium was used to evaluate the mechanism for the procoagulant effect in vivo. The results showed that astragalin had good procoagulant effects compared with the control group in vitro. Compared with the model group in vivo, astragalin could shorten the coagulation time and significantly increase the number of platelets. Meanwhile, astragalin could significantly reduce the effectual time of PT and APTT and increase the content of FIB. The contents of 6-keto-PGF1α and eNOS significantly decreased. Astragalin could increase whole blood viscosity (WBV), plasma viscosity (PV), erythrocyte sedimentation rate (ESR) and packedcell volume (PCV). All of the above revealed that astragalin had good procoagulant effects by promoting the intrinsic and extrinsic coagulation system.

Abstract
Kaempherol-3-O-β-d-glucoside, known as astragalin, is one of flavonoids found in a variety of plants including Cuscuta australis R.Br. In recent studies, astragalin possess many biological functions. Although astragalin is formed by linking glucose to kaempherol, its biological activity is not the same as kaempferol. In vivo, 17 β-estradiol (E2) is hydroxylated by cytochrome P450 (CYP) 1B1 to form 4-hydroxy-E2 (4-OH-E2). This metabolite 4-OH-E2 is highly expressed in tumor tissues and has a strong tumorigenic effect. In this paper, the inhibition of astragalin and kaempferol on the activity of cytochrome 1B1 catalyzing estradiol to form 4-hydroxy-estradiol was studied, and the structure-activity relationship between astragalin and kaempferol due to their structural differences was discussed. This study showed that astragalin could inhibit the activity of CYP1B1. The inhibitory effect of astragalin (IC50 5.36 ± 1.13 μM) was weaker than kaempferol (IC50 0.45 ± 0.11 μM). For astragalin, Ki and Vmax values were 4.061 ± 0.737 μM and 1.457 pmol/μg protein/min, while for kaempferol, Ki and Vmax values were 2.631 ± 0.381 μM protein/min and 1.023 ± 0.231 pmol/μg. By kinetic analysis, astragalin and kaempferol were all mixed inhibition, indicating that although astragalin is formed by linking glucose to kaempherol, its inhibitory mechanism on CYP1B1 remained unchanged, and still belonged to a mixed inhibition. The data indicated that astragalin has been able to inhibit the metabolism of estradiol into the carcinogenic metabolite 4-hydroxyl-estradiol in vivo and illustrated an anti-tumor mechanism of astragalin. This study helps to reveal the structure-activity relationship between CYP1B1 activity and its inhibitors.

Abstract
Astragalin, a bioactive component of medicinal plants such as Rosa agrestis, has anti-inflammatory and antioxidant features. Induction of heme oxygenase (HO)-1 is an effective strategy to reduce excessive generated oxidants during the pathogenesis of acute lung injury (ALI). The aim of the present study is to investigate that whether the anti-inflammatory and antioxidant features of astragalin is HO-1 dependent in lipopolysaccharide (LPS)-induced ALI. Sprague-Dawley rats were used in animal study. Intratracheal LPS was performed to induce experimental ALI model. Astragalin was administrated 1 h after LPS challenge. Human lung epithelial cells were used in cell study. Samples from rats were harvested at 24 h post LPS challenge. Astragalin treatment inhibited LPS-induced inflammatory cells infiltration in the lung and pulmonary edema. Astragalin treatment markedly enhanced the activity of HO-1 compared with vehicle-treated group at 24 h post LPS challenge. Levels of lipid hydroperoxide, a marker for oxidative stress, were decreased in astragalin-treated animals compared with vehicle-treated group. However, the protective effect of astragalin on LPS-induced ALI was abolished in an inhibitor of HO-1-treated animals. Moreover, the astragalin-induced the upregulation of HO-1 in human lung epithelial cells was inhibited when nuclear factor erythroid-2-related factor 2 (Nrf2) was silenced by small interfering RNA. Astragalin reduces LPS-induced ALI via activation of Nrf2/HO-1 pathway.

Abstract
Astragalin (AG) is a biologically active flavonoid compound that can be extracted from a number of medicinal plants. However, the effects of AG on osteoblastic differentiation in mouse MC3T3-E1 cells and on bone formation in vivo have not been studied fully. In this study, we found that the activities of alkaline phosphatase (ALP) and mineralized nodules in MC3T3-E1 cells were both significantly increased after treatment with AG (5, 10, and 20 μM). Meanwhile, the mRNA and protein levels of osteoblastic marker genes in MC3T3-E1 cells after AG treatment were markedly increased compared with a control group. In addition, the levels of BMP-2, p-Smad1/5/9, and Runx2 were significantly elevated in AG-treated MC3T3-E1 cells. Moreover, we found that the protein levels of Erk1/2, p-Erk1/2, p38, p-p38, and p-JNK were also significantly increased in AG-treated MC3T3-E1 cells compared to those in the control group. Finally, in vivo experiments demonstrated that AG significantly promoted bone formation in an ovariectomized (OVX)-induced osteoporotic mouse model. This was evidenced by significant increases in the values of osteoblast-related parameters (BFR/BS, MAR, Ob.S/BS, and Ob.N/B.Pm) and bone histomorphometric parameters (BMD, BV/TV, Tb.Th, and Tb.N.) in OVX mice after AG treatment (5, 10, and 20 mg/kg). Collectively, these results demonstrated that AG may promote osteoblastic differentiation in MC3T3-E1 cells via the activation of the BMP and MAPK pathways and promote bone formation in vivo. These novel findings indicated that AG may be a useful bone anabolic agent for the prevention and treatment of osteoporosis.

Abstract
Spermatogenic dysfunction is a common complication in men with diabetes and is the most important manifestation of diabetes-related male reproduction damage. Astragalin (AG) is one of the main flavonoids from Cuscuta chinensis, which has rich pharmacological activities. This study aimed to establish whether AG may contribute to the recovery from spermatogenic dysfunction. AG (3.3, 10 and 30 mg/kg) and Clomiphene (5 mg/kg) were orally administered to streptozotocin-induced diabetic male mice for 8 weeks. After the experiments performed, reproductive organs, sperm parameters and histomorphological changes were analysed. Antioxidant and anti-inflammatory capacity were estimated in testicular tissues. The results revealed that AG significantly improved the reproductive organs, sperm parameters and testicular morphology to different degrees in diabetic mice. Nitric oxide (NO) and malondialdehyde (MDA) levels were significantly reduced, and the activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and catalase (CAT), markedly increased in the testicular tissue after AG was administered. Interestingly, AG also downregulated the protein expressions of tumour necrosis factor-α (TNF-α) and inducible nitric oxide synthase (iNOS) in testes. In conclusion, AG is a potential beneficial agent to protect diabetic-induced spermatogenic dysfunction in male mice by increasing antioxidant enzymes activities and inhibiting inflammation.

Abstract
Though Astragalin (kaempferol-3-glucoside) contained in Paeonia lactiflora and other plants was known to have anti-oxidant, antiinflammatory, and anti-tumor activity, the anti-tumor mechanism of Astragalin has never been reported in melanomas until now. Thus, in the present study, the underlying apoptotic mechanism of Astragalin isolated from Aceriphyllum rossii was elucidated in A375P and SK-MEL-2 melanoma cells. Astragalin exerted cytotoxicity in A375P and SK-MEL-2 cells in a concentration-dependent manner. Also, Astragalin significantly increased the number of TdT-mediated dUTP nick end labeling positive cells and sub-G1 population as a feature of apoptosis in A375P and SK-MEL-2 cells compared with untreated control. Consistently, western blotting revealed that Astragalin activated caspase 9/3 and Bax, cleaved poly (ADP-ribose) polymerase, and attenuated the expression of cyclin D1, Mcl-1, and Sry-related HMg-Box gene 10 (SOX10) in A375P and SK-MEL-2 cells. Of note, ectopic expression of SOX10 reduced the apoptotic ability of Astragalin to inhibit proliferation, cleave poly (ADP-ribose) polymerase, and caspase 3 in A375P and SK-MEL-2 melanoma cells. Overall, our findings provide evidence that Astragalin induces apoptosis in A375P and SK-MEL-2 melanoma cells via activation of caspase9/3 and inhibition of SOX10 signaling.

Abstract
We report the first investigation of the chemical constituents of Zygophyllum melongena Bunge, a species growing in Mongolia. The quinovic acid glycosides 3-O-(β-D-glucopyranosyl)quinovic acid and 3-O-(β-D-glucopyranosyl)quinovic acid (28→1)-(β-D-glucopyranosyl) ester were identified in the chloroform fraction along with the flavonoid glycoside astragalin. The n-butanol fraction contained (+)-D-pinitol as the major component, a cyclitol with anti-diabetic properties. The structures of the isolated natural products were confirmed using ESI-MS and NMR spectroscopy ((1)H, (13)C, COSY, HSQC, HMBC, NOESY and ROESY). This is the first report of the isolation of (+)-D-pinitol from the genus Zygophyllum.

Abstract
Astragalin, a bioactive component isolated from Rosa agrestis, has been described to exhibit anti-inflammatory activity. The aim of this study was to investigate the anti-inflammatory effects and the underlying mechanisms of astragalin on IL-1β-stimulated human osteoarthritis chondrocyte. The production of NO and PGE2 was detected by Griess reaction and ELISA. The expression of iNOS and COX-2 was detected by western blotting. The expression of NF-κB and MAPKs was detected by western blot analysis. We found that astragalin dose-dependently inhibited IL-1β-induced NO and PGE2 production, as well as iNOS and COX-2 expression. Meanwhile, western blot analysis showed that astragalin inhibited IL-1β-induced NF-κB and MAPK activation in human osteoarthritis chondrocyte. In addition, astragalin was found to activate PPAR-γ. The inhibition of astragalin on IL-1β-induced NO and PGE2 production can be reversed by PPAR-γ antagonist GW9662. Astragalin suppressed IL-1β-induced inflammatory mediators via activating PPAR-γ, which subsequently inhibited IL-1β-induced NF-κB and MAPK activation. Astragalin may be a potential agent in the treatment of osteoarthritis.

Abstract
BACKGROUND Tea brewed from the leaves of persimmon or Rosa agrestis have several medical functions including treating allergy, antiatopic dermatitis, and anti-inflammatory effects. The objective of this study was to investigate the molecular mechanisms of astragalin, a main flavonoid component isolated from these herbs, in modifying lipopolysaccharide (LPS)-induced signaling pathways in primary cultured mouse mammary epithelial cells (mMECs). MATERIALS AND METHODS The mMECs were treated with LPS in the absence or presence of different concentrations of astragalin. The expression of proinflammatory cytokines tumor necrosis factor α, and interleukin 6, as well as nitric oxide production were determined by enzyme-linked immunosorbent assay and Griess reaction, respectively. Cyclooxygenase-2, inducible nitric oxide synthase, toll-like receptor 4 (TLR4), nuclear factor-κB (NF-κB), inhibitor protein of NF-κB (IκBα), P38, extracellular signal-regulated kinase, and c-Jun N-terminal kinase were measured by Western blot. RESULTS The results showed that astragalin suppressed the expression of tumor necrosis factor α, interleukin 6, and nitric oxide in a dose-dependent manner in mMECs. Western blot results showed that the expression of inducible nitric oxide synthase and cyclooxygenase-2 was inhibited by astragalin. Besides, astragalin efficiently decreased LPS-induced TLR4 expression, NF-κB activation, IκBα degradation, and the phosphorylation of p38, extracellular signal-regulated kinase in BMECs. CONCLUSIONS Our results indicated that astragalin exerts anti-inflammatory properties possibly via the inactivation of TLR4-mediated NF-κB and mitogen-activated protein kinases signaling pathways in LPS-stimulated mMECs. Thus, astragalin may be a potential therapeutic agent for bovine mastitis.

Abstract
Mastitis is a prevalent and economic disease around the world and defined as infection and inflammation of the mammary gland. Astragalin, a bioactive component isolated from persimmon or Rosa agrestis, has been reported to have anti-inflammatory properties. To investigate the potential therapeutic effect of astragalin in mastitis, a murine model of mastitis was induced by administration of LPS in mammary gland. Astragalin was applied 1h before and 12h after LPS treatment. The results showed that astragalin attenuated the infiltration of inflammatory cells, the activity of myeloperoxidase (MPO) and the expression of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and interleukin-1β (IL-1β) in a dose-dependent manner. Additionally, Western blotting results showed that astragalin efficiently blunt decreased nuclear factor-kappaB (NF-κB) activation by inhibiting the degradation and phosphorylation of IκBα and the nuclear translocation of p65. These results suggested that astragalin exerts anti-inflammatory properties in LPS-mediated mastitis, possibly through inhibiting inhibition of the NF-κB signaling pathway, which mediates the expression of pro-inflammatory cytokines. Astragalin may be a potential therapeutic agent against mastitis.
