Abstract:
OBJECTIVETo determine the chemical constituents of Jatropha curcas.
METHODChemical constituents were obtained using various chromatography methods including silica gel column chromatography and HPLC. The structures of isolated compounds were determined by spectroscopic methods including 1H-NMR, 13C-NMR and MS.
RESULT AND CONCLUSIONFourteen phenolic compounds were obtained from the stems of J. curcas and their structures were identified to be 5,4'-dihydroxy-3, 7, 3'-trimethoxyflavone (1), 5, 3', 4'-trihydroxy-3,7-dimethoxyflavone (2), 3-O-methylquercetin (3), 5, 6, 7-trimethoxycoumarin (4), tomentin (5), isoscopoletin (6), omega-hydroxypropioquaiacone (7), coniferaldehyde (8), 3, 5-dihydroxy-4-methoxybenzaldehyde (9), vanillic acid (10), isovanillin (11), 4-hydroxybenzaldehyde (12), cimifugin (13) and (E)-3-hydroxy-5-methoxy-stilbene (14). Among them, compounds 1-4 and 6-14 were isolated from the genus of Jatropha for the first time.
