【Abstract】 AIM: To study flavonoids from the aerial parts of Astragalus mongholicus. METHODS: The chemical constituents were isolated and purified with various column chromatography and the structures were identified by spectal analyses. RESULTS: Six flavonoids and one triterpene saponin were isolated and their structures were identified as kaempferol-4′-methylether-3-β-D-glucoside(Ⅰ), isorhamnetin -3-β-D-glucoside(Ⅱ),isoquercitrin(Ⅲ), complanaruside(Ⅳ),odoratin(Ⅴ), odoratin-7-O-β-D-glucoside(Ⅵ) and alexandroside Ⅰ(Ⅶ). CONCLUSION:Compound Ⅴ were isolated from Genus Astragalus for the first time and compounds Ⅳ、Ⅵ、Ⅶ were firstly isolated from this plant.更多还原
