摘要：
Two new triterpenoid saponins, asteryunnanosides F and G, were isolated from the roots of Aster yunnanensis. Their structures were determined as oleanolic acid-28-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranoside and 3-O-beta-glucopyranosyloleanolic acid-28-O-beta-D-glucopyranosyl-(1-->6)-[alpha-L-rhamnopyranosyl-(1-->2)]-beta-D-glucopyranoside by spectral data, especially 2D NMR analysis including COSY, HETCOR, HOHAHA, and ROESY techniques, and chemical transformation.
