A new cytotoxic Annonaceous acetogenin, giganin (1), was isolated from the bark of Goniothalamus giganteus (Annonaceae). This compound represents a new type of Annonaceous acetogenin lacking tetrahydrofuran or epoxide rings along the aliphatic chain, and its structure was elucidated by 1H and 13C NMR, MS, COSY, and single-relayed COSY. © 1993.
