A mixture of acylglucosyl sterols together with ${\beta}-sitosterol$, ${\beta}-sitosterol\;3{\beta}-O-glucoside$ and fatty acids was isolated from the roots of Caragana chamlagu as their acetate forms and the structure elucidated by chemical and spectroscopic means. The major acylglucosyl sterol was ${\beta}-sitosteryl\;3-O-[6'-O-oleoyl]-{\beta}-D-glucopyranoside$ while the minor components were $6'-O-palmitoyl-\;and\;6'-O-stearoyl-{\beta}-D-glucosyl$ sitosterol congeners. The isolation and structure elucidation of these acylglucosyl sterols are reported for the first time from the genus Caragana.
