Abstract

Zeylasteral and desmethylzeylasterone, two new triterpenes from Kokoona zeylanica have been shown to be 2,3-dihydroxy-6,23-dioxo-24-nor-D:A-friedo-oleana-1,3,5(10),7-tetraen-29-oic acid methyl ester (20α) and 2,3-dihydroxy-6-oxo-24-nor-D:A-friedo-oleana-1,3,5(10),7-tetraen23,29-dioic acid (20α), respectively, and have been related to trimethylzeylasterone. A partial synthesis of trimethylzeylasterone starting from pristimerin has been achieved.
