['To study the chemical constituents of the stems of Akebia trifoliata (Thunb.) Koidz. var. australis (Diels) Rehd.', 'The compounds were isolated and purified by recrystallization and chromatography on silica gel and ODS column. Their structures were elucidated on the basis of physicochemical properties and spectral analysis.', 'Six compounds were identified as 2 alpha, 3 beta,23-trihydroxyolean-12-en-28-oic acid O-beta-D-xylopyranosyl-(1 --> 3)-O-alpha-L-rhamnopyranosyl-(1 --> 4)-O-beta-D-glucopyranosyl-(1 --> 6)-beta-D-glucopyranosyl ester (I), 2 alpha, 3 beta, 23-trihydroxyurs-12-en-28-oic acid O-beta-D-xylopyranosyl-(1 --> 3)-O-alpha-L-rhamnopyranosyl-(1 --> 4)-O-beta-D-glucopyranosyl-(1 --> 6 )-beta-D-glucopyranosyl ester (II), 2 alpha, 3 beta, 23-trihydroxyolean-12-en-28-oic acid O-alpha-L-rhamnopyranosyl-(1 --> 4)-O-beta-D-glucopyranosyl-(1 --> 6)-beta-D-glucopyranosyl ester (III), 2alpha, 3beta, 23-trihydroxyurs-12-en-28-oic acid O-alpha-L-rhamnopyranosyl-(1 --> 4)-O-beta-D-glucopyranosyl-(1 --> 6)-beta-D-glucopyranosyl ester (IV), 2 alpha, 3 beta, 23-trihydroxyolean-12-en-28-oic acid O-beta-D-glucopyranosyl ester (V), 2 alpha, 3 alpha, 23-trihydroxyurs-12-en-28-oic acid O-beta-D-glucopyranosyl ester (VI).'] Does [ A new triterpenoid saponin from stem of Akebia trifoliata ]?
