Abstract

Further studies on the roots of Goniothalamus donnaiensis Finet et Gagnap (Annonaceae) led to the isolation of two pairs of Annonaceous acetogenins, donnaienin C (1) and 34-epi-donnaienin C (1′), donnaienin D (2) and 34-epi-donnaienin D (2′), containing a rare γ-hydroxymethyl-γ-lactone moiety and a C-4-acetoxy group. Their structures were elucidated by spectral data and chemical derivatization. Preliminary pharmacological tests showed that the mixture of donnaienin C(1) and 34-epi-donnaienin C (1′) inhibited human hepatoma (Bel) cell lines in vitro (IC50, 7.1 µg/ml).
