Abstract:
A new sweet triterpene glycoside, periandrin V, was isolated from the roots of Periandra dulcis and identified as 3 beta-O-[beta-D-xylopyranosyl-(1-->2)-beta-D-glucuronopyranosyl]-25 -al-olean-18(19)-en-30-oic acid on the basis of chemical and spectral evidence. The structure of an acid-rearranged product of periandrin V and the parent compound, periandrin I, was determined as 1(10-->25) abeo-3 alpha, 25 alpha-epoxy-olean-5(10), 18-dien-30-oic acid methyl ester.
