Abstract
Three quassinoids, eurycolactone D (1), eurycolactone E (2) and eurycolactone F (3) were isolated from the roots of Eurycoma longifolia Jack. The structures of 1-3 were elucidated by spectroscopic methods, and that of 3 was further confirmed by X-ray crystallography. The known quassinoids, laurycolactone B (4) and eurycomalactone (5) were also identified.Entities:
