Article abstract of DOI:10.1007/s10600-011-9946-9

A new triterpene glycoside of the cycloartane series that was called askendoside H was isolated from r.oots of Astragalus taschkendicus Bunge (Leguminosae). Its structure was elucidated based on chemical transformations and spectral data. Askendoside H was a bisdesmoside of cycloorbigenin C, 23R,24Rcycloartan- 3β,6α,16β,23,24,25-hexaol 3-O-[(α-L-arabinopyranosyl)(1→2)-β-D-xylopyranoside] 23-O-β- D-glucopyranoside.
