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.
Results And Conclusion:
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.
