Objective:
To study the chemical constituents of Hedyotis diffusa.
Methods:
Column chromatographic techniques were used for isolation and purification of chemical constituents of this plant and their structures were identified by spectroscopic analysis.
Results:
Five compounds were isolated and identified as scandoside methyl ester (I), deacetylasperulosidic acid methyl ester (II), 10-dehydrogeniposide (III), 2-hydroxy-3-methylanthraquinone (IV), stigmasterol (V), respectively.
Conclusion:
Compound II as iridoids was isolated from Hedyotis diffusa for the first time, compound III as iridoids was isolated from genus Hedyotis for the first time.
