Abstract:
OBJECTIVETo investigate the chemical constituents from Hedyotis diffusa.
METHODThe compounds were isolated and purified by various chromatographic techniques and identified by their physicochemical properties and spectral data.
RESULTEight compounds had been reported in last paper, and this time eight more compounds were isolated and identified as 6-hydroxystigmasta-4,22-dien-3-one (1), 3-hydroxystigmasta-4,22-dien-7-one (2), 2-hydroxy-3-methylanthraquinone (3), 2,6-dihydroxy-3-methyl-4-methoxyanthraquinone (4), iso-scutellarein (5), isoetin (6), aesculetin (7), gypsogenic acid (8).
CONCLUSIONCompounds 1-3, 5-8 were obtained from the genus Hedyotis for the first time.
