Chemical investigation of hot hexane extract of the stem bark of Gordonia ceylanica afforded a new triterpenoid, $3{\beta}-acetoxy-28-hydroxyolean-12-ene$ (1) and three other oleanane triterpenoids, $3{\beta}-hydroxyolean-12-ene$ (2), $3{\beta}-acetoxyolean-12-ene$ (3), and $3{\beta}-acetoxyolean-12-en-11-one$ (4) which are new to the species. Structure of compound 1 was suggested by $^1H\;NMR,\;^{13}C\;NMR$ and MS spectral data and confirmed by converting to previously reported compound, erythrodiol diacetate (5). Structures of 2, 3 and 4 were established by comparison of the spectral data with the previously reported compounds. Further the acid hydrolysate of 4 was identical with $3{\beta}-hydroxyolean-12-en-11-one$ (6).
