Abstract:
A new rearranged pentanortriterpenoid (trijugin C) and a new pregnane (3β,4α-dihydroxypregnan-16-one) were isolated from the EtOH extract of Trichilia connaroides (Meliaceae). Trijugin C has been shown to be a derivative of methyl angolensate with a novel carbon skeleton. The structures were elucidated on the basis of spectral analysis including 1 H- 1 H COSY, HMQC, HMBC, and NOESY experiments. The possible biogenetic pathway of trijugin C is discussed.Key words: Trichilia connaroides, Meliaceae, pentanortriterpenoid, trijugin C, pregnane.
