Abstract

Terminalia foetidissima Griff. is a tree native of the Philippines. Chemical investigation of dichloromethane extract of the leaves of T. foetidissima has led to the isolation of cycloeucalenol (1), squalene (2), long-chain hydrocarbons (3) and a mixture of 24-methylene-pollinastanol (4), β-sitosterol (5) and stigmasterol (6) in about 4:3:1 ratio. The structure of compound 1 was elucidated by extensive 1D and 2D NMR spectroscopy and confirmed by comparison of its NMR data with those reported in the literature. The structures of compounds 2-6 were identified by comparison of their NMR data with literature data.
