The hexane extract of leaves of Trichilia claussenii yielded the new triterpenoid 24-methylene-26 hydroxycycloartan-3-one, 24-methylenecycloartanol fatty acids derivatives, caryophyllene epoxide, a mixture of to-phenyl alkanoic and alkenoic acids, plastocromenol, ct-tocopherol, squalene, and a mixture of sitosterol and stigmasterol as free alcohols and esterified by fatty acids. The methanol extract afforded N-methyl-proline, 4 hydroxy-N-methylproline, ~o-phenyl alkanoic acids and a mixture of/3-O-D-glucopyranosides of sitosterol and stigmasterol.
