摘要：

A new triterpene cycloartane glycoside called askendoside K was isolated from roots of Astragalus taschkendicus Bunge (Leguminosae). The structure of this glycoside was established using chemical and biochemical transformations and spectral data. Askendoside K was a bisdesmoside of cycloorbigenin C and had the structure 23R, 24R-cycloartan-3 beta,6 alpha,16 beta,23,24,25-hexaol 3-O-[(alpha-L-arabinopyranosyl)(1 -> 2)-beta-D-xylopyranoside], 23-O-[(beta-D-glucuronopyranosyl)(1 -> 2)-beta-D-glucopyranoside].
