摘要：

An acetone extract of aerial parts of Rosa laevigata was found to contain 16 components, including derivatives of ursolic, euscaphic and oleanolic acids as well as glucosides of sterols. Among them, 2-alpha-methoxyursolic acid, 11-alpha-hydroxytormentic acid, tormentic acid 6-methoxy-beta-glucopyranosyl ester and stigmasta-3-alpha,5-alpha-diol 3-O-beta-D-glucopyranoside are new compounds. Their structures were established by chemical and spectral methods.
