Abstract

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-β-D-glucopyranosyl-(1→6)-β-D-glucopyranoside and 3-O-β-glucopyranosyloleanolic acid-28-O-β-D-glucopyranosyl-(1→6)-[α-L-rhamnopyranosyl-(1→2)]β-D-glucopyranoside by spectral data, especially 2D NMR analysis including COSY, HETCOR, HOHAHA, and ROESY techniques, and chemical transformation.

Key words
