The bitter principles in the leaves and vines of Momordica charantia L. (Cucurbitaceae), momordicines I, C30H48O4*H2O, and II, C36H58O9, were isolated and their structures were elucidated as 3β,7β,23ξ-trihydroxy-cucurbita-5,24-dien-19-al and its 23-O-β-glucopyranoside, respectively.The structure of momordicine III, which was isolated as its acetate, C48H68O16*1/2 H2O, is indicated to be a 23-O-β-glucopyranoside of 3β,7β,23ξ-trihydroxy-24-oxo-cucurbita-5,25-dien-19-al by the spectral and chemical evidence.KEYWORDS - Momordica charantia; Cucurbitaceae; bitter principle; tetracyclic triterpene; cucurbitacin; momordicines I, II and III; 3β,7β23ξ-trihydroxy-cucurbita-5,24-dien-19-al; 3β,7β,23ξ-trihydroxy-24-oxo-cucurbita-5,25-dien-19-al
