Abstract:
Two triterpen glycoside belong to cucurbitacin group, momordicosid A (3-O-β- gentiobiosyl cucurbit-5-en- 3β, 22 (S), 23 (R), 24 (R), 25-pentaol) and momordicosid B (3-O- β- D- xylopyranosyl (1-4)- [β-D- glucopyranosyl (1-6)]- β- D- glucopyranosyl cucurbit-5-en-3 β, 22 (S), 23 (R), 24 (R), 25-pentaol) were isolated and identified from the defatted seeds of Momordica charantia L. attained at Tuy Hoa, Phu Yen. Their structures were determined on the basis of spectra including IR, FAB-LR-MS, 1H-NMR, HMBC and 1H-NMR
