Abstract

7-Methyljuglone, isodiospyrin and three glucuronides of oleanolic acid were isolated from the lipophilic and the methanol extracts, respectively, of the root bark of Diospyros zombensis. Cytotoxic activities of the naphthoquinones and strong molluscicidal activity of 3-O-[O-α-L-rhamnopyranosyl-(1 → 3)-β-D-glucuronopyranosyl]-oleanolic acid were shown. In addition hyperoside, quercitrin and quercetin-3-O-β-D-glucuronopyranoside were isolated from a methanol extract of the leaves.
