The methanol extract of stems of Trichilia claussenii yielded three new steroids: 2r,3a_dihydroxyandrostan-16-one 2p,19-hemiketal, 2cr,3b-dihydroxypregnan- 16-one 2/?,19-hemiketal, 2fl,38-dihydroxypregnan-16-one. Two known steroids 2fi,3/?,4B-trihydroxypregnan-16-one, 2c(,3ec,48-trihydroxypregnan-16 one and a mixture of sitosterol and stigmasterol j?-O-D-glucopyranosides were also isolated. The structures of the isolated compounds were determined on the basis of spectroscopic analysis.
