Using brine shrimp lethality for activity-directed fractionation, goniothalamicin (I), a new tetrahydroxy-mono-tetrahydrofuran fatty acid gamma-lactone (acetogenin), has been isolated from ethanolic extracts of the stem bark of Goniothalamus giganteus Hook. f., Thomas (Annonaceae). This novel
The structure of annomontacin [I], a novel monotetrayhydrofuran fatty acid gamma-lactone (acetogenin) isolated from the seeds of Amnona montana, was determined by spectral analysis. The cytotoxicities in vitro of annomontacin [I], annonacinone [2], and annonacin were measured against murine leukemia
