Objective:
To investigate the chemical constituents from Hedyotis diffusa.
Method:
The compounds were isolated and purified by various chromatographic techniques and identified by their physicochemical properties and spectral data.
Result:
Eight 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).
Conclusion:
Compounds 1-3, 5-8 were obtained from the genus Hedyotis for the first time.
