摘要
Another seven components from the roots of Astragalus exilis A.Kor. (Leguminosae) were identified using spectral data and chemical transformations. A triterpenoid of genin nature was identical to cyclosiversigenin. One compound of glycosidic nature turned out to be a new cycloartane glycoside called by us cycloexoside B of structure 20R,24S-epoxycycloartan-3β,6α,16β,25-tetraol 3-O-β-D-(2-Oacetyl) xylopyranoside. Five glycosides were identified as cyclosiversigenin 3-O-β-D-xylopyranoside and cyclosiversiosides B, C, D, and G.
