Three new alkaloids, picrasidines W (1), X (2) and Y (3), were isolated from the wood of Picrasma quassioides BENNET (Simaroubaceae). Their structures were determined by spectral and chemical evidence. Previously isolated picrasidine Q (4) was unambiguously determined by X-ray crystallographic analysis.
