Abstract
The liposoluble constituents in Momordicae Semen were investigated in the present study. By silica gel, Sephadex LH-20 column chromatography, and semi-preparative HPLC, 22 compounds were isolated and purified from dichloromethane and ethyl acetate fraction. Based on NMR and MS spectra analyses, these compounds were identified as lupeol (1), 5-(1'-hydroxypentyl)-5H-furan-2-one (2), palmitic acid (3), viscumamide (4), clavatustide C (5), laxanol (6), threo-1-(4-hydroxyphenyl)-2-{4-[2-formyl-(E)-vinyl]-2-methoxyphenoxyl}-propane-1, 3-diol (7), α-spinasterol-3-O-β-D-glucoside (8), chushizisin F (9), ehletianol C (10), tanegool (11), (7R, 8R, 8'R)-4'-guaiacylglyceryl-evofolin B (12), ligballinone (13), (7R, 8S, 8'R)- 4, 4', 9-trihydroxy- 7, 9'-epoxy- 8, 8'-lignan (14), chushizisin I (15), chushizisin A (16), chushizisin G (17), p-coumaraldehyde (18), α-spinasterol (19), p-hydroxybenzoic acid (20), chushizisin E (21), and 3-[2-(4-hydroxyphenyl)-3-hydroxyphenyl-2, 3-dihydro-1-benzofuran-5-yl] propane-1-ol (22), respectively. Compounds 1-17 were isolated from Momordica cochinchinensis for the first time. Compound 2 was a new natural product while compounds 4 and 5 were first found in the terrestrial organism.
