Commonly consumed honeys from sixteen different single floral sources were analyzed for their in vitro antioxidant capacities by several methods including DPPH, ABTS, FRAP, SASR and MDA assays. The total polyphenol contents varied among the tested honeys and were highly correlated to their

Antibacterial bioassay guided fractionation of acetone extracts of Astragalus brachystachys resulted in isolation of sclareol and two related labdane-type diterpenoids, 14R-epoxysclareol and 6beta-hydroxysclareol. The antibacterial activity of the isolated compounds was measured and it was deduced

This work introduced an eco-friendly approach for the synthesis of sliver nanoparticles (AgNPs) with a water-soluble fraction of polysaccharides extracted from the roots of Astragalus membranaceus (AMWP). AMWP mediated AgNPs (AMWP-AgNPs) were successfully synthesized using 1.0mM AgNO3 and 1.25mg/mL

BACKGROUND The phytochemical study and biological activities of Astragalus armatus Willd. subsp. numidicus (Fabaceae) pods, an endemic shrub of Maghreb, are reported. OBJECTIVE This study isolates the secondary metabolites and determines the bioactivities of Astragalus armatus pods. METHODS The

OBJECTIVE In a search for finding novel therapeutic agents, extracts from an endemic Lebanese plant, Astragalus angulosus, were evaluated for their potential in-vitro antibacterial and antibiofilm activities against three Gram-positive bacterial strains; Staphylococcus epidermidis (CIP444),

UNASSIGNED Perennial legumes have been used as edible or medicinal plants since ancient times. The focus of the current study are perennial legumes-Trifolium pratense L., T. medium L., Medicago sativa L., M. lupulina L., Onobrychis viciifolia Scop., Astragalus glycyphyllos L. and A. cicer L.-of

Astragalus polysaccharides (APS), one of the major active components in Astragalus membranaceus, is an effective immunomodulator used in the treatment of immunological diseases in China. However, the anti-infective action and mechanism of APS is not fully known. In the present study, we found that

The purpose of the present study was to discover antimicrobial endophytic fungi from Astragalus chinensis. Three fungal endophytes with antibacterial activity were isolated and determined as Chaetomium sp. HQ-1, Fusarium sp. HQ-7 and Fusarium sp. HQ-9 based on the

Astragalus is a very interesting plant genus, well-known for its content of flavonoids, triterpenes and polysaccharides. Its secondary metabolites are described as biologically active compounds showing several activities, e.g., immunomodulating, antibacterial, antiviral and hepatoprotective.

Traditional medicines are composed of herbal formulations and their active ingredients and constituents which play a crucial role in the treatment of various human ailments. Astragalus eremophilus and Melilotus indicus (L.) All. (syn. Melilotus parviflora Desf.) are used traditionally as

A new lignan glycoside, astrayunoside A (1), along with eight known compounds (2-9), were obtained from the methanol extract of roots of Astragalus yunnanensis. All the compounds were obtained from A. yunnanensis for the first time. Their structures were elucidated by extensive spectroscopic

Astragalus membranaceus lectin (AML) was abstracted as a supposedly novel agglutinin of 67 kDa from the seeds of Astragalus membranaceus. The seeds of Astragalus membranaceus were treated with acetate, ammonium sulfate precipitation, and purified by HiTrap SP XL ion column and Superdex G25 gel

Chinese herbal medicine and gentamycin were used separately in the treatment of 75 cases of gastric disease by campylobacter pyloridis (CP). Surveying the changes of the gastrofiberscope, pathological test, bacteriology and immunology. This study, found that in the Chinese herbal medicine group

From the roots of Astragalus melanophrurius eight known saponins (1-8) were isolated. Based on spectral data (IR, 1H- and 13C-NMR, and FABMS), the structures were established as astrasieversianins II (1) and X (4), astragalosides I (2), II (3), IV (5) and VI (7), and cyclocanthosides E (6) and G

The effects of Astragalus membranaceus and Lycium barbarum on the growth performance and non-specific immunity of grass carp and Nile tilapia were studied. Herb extracts of Chinese medicinal herbs (2 g kg-1 or 20 g kg-1) were incorporated into food waste based fish feed pellets. Fish growth and
