ABSTRACT
Besides four known compounds, a new triterpenoid saponin was isolated from the stems of Gymnema sylvestre. The structure of the new triterpenoid saponin was established as 3ß,16ß,22α-trihydroxy-olean-12-ene 3-O-ß-D-xylopyranosyl-(1 â 6)-ß-D-glucopyranosyl-(1 â 6)-ß-D-glucopyranoside (1) on the basis of 1D and 2D NMR techniques, including COSY, HMBC, HMQC, and NOESY correlations. Four known compounds 2, 3, 4, and 5 were identified on the basis of spectroscopic data.
