OBJECTIVE
Traditional medicinal use of species of the genus Drypetes is widespread in the tropical regions. The aim of this review is to systematically appraise the literature available to date on phytochemistry, ethnopharmacology, toxicology and bioactivity (in vitro and in vivo) of crude extracts
Four hitherto unknown dinorditerpenoids, dryperreins A-D of the pimarane class, together with eight known triterpenoids, were isolated from twigs and leaves of Drypetes perreticulata. The structures of dryperreins A-D were elucidated on the basis of detailed spectroscopic analysis as
