[Analysis of the chemical constituents of Hedyotis diffusa].
OBJECTIVE
To analyze the chemical constituents of Hedyotis diffusa.


METHODS
Column chromatographies were used to isolate and purify the chemical constituents of this plant, and their structures were identified by spectral analysis and physicochemical properties.


CONCLUSIONS
Seven compounds were isolated and identified as p-coumaric acid (I), methyl-p-coumarate (II), 2-formyl-5- hydroxymethylfuran (III), quercetin (IV), kaempferol (V), beta-sitosterol(VI) and daucosterol(VII), respectively, among which the compounds II and III were isolated from Hedyotis diffusa for the first time.
