Abstract |
Chemical investigation of the hot hexane extract of the stem bark of Gordonia ceylanica afforded two new oleanane triterpenoids, 3beta-acetoxy-11alpha, 13beta-dihydroxyolean-12-one and 3beta,11alpha-diacetoxy-13beta-hydroxyolean-12-one (2) The attempted acid hydrolysis of these two compounds resulted the dehydration and subsequent methyl group migration to afford the taraxarane triterpenoids 3beta,11alpha-dihydroxytaraxer-14-en-12-one (4) and 3beta-hydroxy-11alpha-acetoxytaraxer-14-en-12-one (5), respectively. These taraxaranes have not been previously reported.
