【Abstract】 AIM:To study the chemical constituents of the roots of Astragalus hoantchy Franch.. METHOD:Isolation and elucidation of the chemical constituents,were conducted by chromatography and spectral evidences. RESULTS and CONCLUSION:Six steroids and four anthraquinones were isolated from the roots of A. hoantchy. Their structures were identified to be stigmastane-3,6-dione (1),5α,8α-epidioxy- (22 E ,24 R )-ergosta-6,22-dien-3β-ol (2),stigmastane-3β,6α-diol (3),daucosterol (4),β-sitosterol (5),stigmasterol (6),chrysophanol (7),emodin (8),physion (9) and aloe-emodin (10) on the basis of spectral data and physical constants. Among them,compounds 1,2,3,7,8,9,10 were isolated from the genus Astragalus for the first time.更多还原
