Two new oleanane-type triterpenes, characterized as 3-oxo-11α,12α-epoxy-oleanan-28,13β- olide and 3-oxo-olean-11-en-28,13β-olide , were isolated from the fruits and seeds of Cedrela montana (Meliaceae). In addition, the known compounds oleanonic acid , a mixture of β-sitosterol and stigmasterol, and the limonoid photogedunin were also isolated. The structures of the new compounds were established by spectroscopic methods, including 2D NMR.
