Cytotoxic and Anti-Platelet Aggregation Constituents from the Root Wood of Melicope semecarpifolia

Abstract

A new acetophenone derivative, melicopone, along with twenty-nine known compounds has been isolated from the root wood of Melicope semecarpifolia. The structure of this new compound was determined using spectral analyses. The compound oxynitidine isolated in this study adds the Melicope genus to the benzo[c]phenanthridine-containing members chemotaxonomically. Three isolates were cytotoxic in P-388 and HT-29 cell lines, and anti-platelet aggregation activities were shown for 10 known compounds.
