Abstract:
Objective To study the chemical constituents from the stems of Acanthopanax gracilistylus. Methods The chemical constituents of the plant were isolated and puried by column chromatography and their structures were elucidated on the basis of physicochemical properties and spectral data. Results A new ent-kaurane glycoside, named kaurane acid glycoside A｛16α,17-dihydroxy-ent-kauran-19-oic 19-[β-D-glucopyranosyl-(1→2)-β-D- glucopyranosyl] ester｝ (1), was isolated from the n-butanol part.
