Astragalus polysaccharide is a major component of radix astragali, a vital qi-reinforcing herb medicine with favorable immune-regulating effects. In a previous animal experiment, we demonstrated that astragalus polysaccharide effectively alleviates ischemia-reperfusion injury (IRI) of cardiac muscle through the regulation of the inflammatory reactions. However, the relationship between this her...

The protective effects of two Chinese herbs, astragalus mongholicus, polygonum multiflorum and astragalus mongholicus-polygonum multiflorum in combination against thymus injury induced by cyclophosphamide were evaluated by transmission electron microscopy, image analysis, DNA gel electrophoresis as well as flow cytometry. Results showed that mice pretreated with cyclophosphamide had degenerated...

Selenium-accumulator plants synthesize selenium compounds that differ from those produced by nonaccumulators. To determine if there are any subcellular differences between accumulators and nonaccumulators in the use of selenomethionine in vitro, polysomes from Astragalus crotalariae (accumulator) and Astragalus lentiginosis (nonaccumulator) were translated in the presence of selenomethionine. P...

Astragalus membranaceus is a famous Chinese medicinal herb. Polysaccharides are the most important functional constituent in Astragalus membranaceus. In the present study, the effects of Astragalus membranaceus polysaccharides (APS) on exercise endurance capacity were evaluated in mice using swimming exercise. The antioxidant properties of APS were also investigated through the 1,1diphenyl-2-pi...

From the aerial parts of Astragalus suberi L., Fabaceae, seven saponins were isolated. Based on spectral data (IR, 1H and 13C NMR and HR-FABMS), the structures were established as 3-O-(beta-D-glucopyranosyl)-soyasapogenol B (1); 3-O-(beta-D-glucuronopyranosyl)-soyasapogenol B (2); 3-O-[beta-D-galactopyranosyl (1-->2)-beta-D-glucopyranosyl]-soyasapogenol B (3); 3-O-[alpha-L-rhamnopyranosyl (1-->...
