Triterpenoid saponins from Triplostegia grandiflora.
Phytochemistry. 1992 Apr; 31(4):1343-7.P

Abstract

Four new oleanane triterpenoid saponins named triplosides D-G were isolated from the roots of Triplostegia grandiflora. Their structures were elucidated on the basis of chemical degradation and spectral evidence. The saponins investigated were: oleanolic acid 3-O-beta-D-xylopyranosyl(1----4)-beta-D-xylopyranosyl(1----3)-beta-D- xylopyranosyl(1----4)-alpha-L-rhamnopyranosyl(1----3)-beta-D- xylopyranosyl(1----3)-alpha-L-rhamnopyranosyl(1----2)-beta-D-xylopyranos ide, oleanolic acid 3-O-beta-D-glucopyranosyl(1----6)-[beta-D- xylopyranosyl(1----4)]-beta-D-glucopyranosyl(1----3)-beta-D- xylopyranosyl(1----4)-alpha-L-rhamnopyranosyl(1----3)-beta-D- xylopyranosyl(1----3)-alpha-L-rhamnopyranosyl(1----2)-beta-D-xylopyranos ide, oleanolic acid 3-O-beta-D-xylopyranosyl(1----3)-beta-D-xylopyranosyl(1----4)- alpha-L-rhamnopyranosyl(1----3)-beta-D-xylopyranosyl(1----3)-alpha-L- rhamnopyranosyl(1----2)-beta-D-xylopyranoside and oleanolic acid 3-O-alpha-L-rhamnopyranosyl(1----3)-beta-D-xylopyranosyl(1---3)-alpha-L- rhamnopyranosyl(1----2)-beta-D-xylopyranoside, respectively. All of them have a common aglycone and are monodesmosides.
