Two new oleanane triterpene glycosides from Gymnema inodorum

Two new oleanane triterpene glycosides were isolated from the n-BuOH extract of Gymnema inodorum. On the basis of spectroscopic evidences, their structures were elucidated as 2 alpha, 3 beta-dihydroxy-olean-12-ene-23, 28-dioic acid-3-O-beta-D-glucopyrano-side and 2 alpha, 3 beta, 15 beta-trihydroxy-olean-12-ene-23, 28-dioic acid-3-O-beta-D-gluco-pyranoside.
