RESUMO

From the leaves of a specimen of Trichilia silvatica Meliaceae, eight known compounds were isolated, namely, two pregnanes, 2α,3β,4β-trihydroxypregnan-16-one (1) and 2β,3β,4β-trihydroxypregnan-16-one (2), three diterpenes, cneorubine X (3), kolavelool (4) and kolavenol (5), in addition to γ-tocopherol, 3-O-β-D-glucopyranosyl-β-sitosterol and 3-O-β-D-glucopyranosyl-stigmasterol. This is the first reported occurrence of pregnane 1, diterpenes 3-5 and µ-tocopherol in the genus Trichilia. The structures of the isolated compounds were determined on the basis of their spectral data.
