Abstract

Chemical investigation of the hot hexane extract of the stem bark of Gordonia ceylanica afforded two new oleanane triterpenoids, 3β-acetoxy-11α, 13β-dihydroxyolean-12-one (1) and 3β,11α-diacetoxy-13β-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 3β,11α-dihydroxytaraxer-14-en-12-one (4) and 3β-hydroxy-11α-acetoxytaraxer-14-en-12-one (5), respectively. These taraxaranes have not been previously reported. (C) 2000 Elsevier Science Ltd.
