Two cytotoxic Annonaceous acetogenins, giganin (1) and longanin (2), were isolated from the leaves and twigs of Asimina longifolia (Annonaceae). These compounds represent the type of Annonaceous acetogenin lacking either tetrahydrofuran or epoxide rings along the aliphatic chain. Compound (2) is novel and giganin is previously known. The planar structures and absolute configurations of both were elucidated by 1H and 13C nmr and ms before and after certain chemical derivatizations. Compound (2) gave cytotoxic ED50 values comparable to those of adriamycin in a panel of human solid tumor cell lines.
