Objective:
To study the chemical constituents of Wikstroemia indica.
Methods:
The constituents were isolated and purified by silica gel chromatography repeatedly, and the structures were determined by spectral data and chemical envidance.
Results:
Six compounds were isolated from its petroleum ether, dichloromethane, acetone and methanol extracts and identified as: daphnoretin-7-O-beta-D-glucoside (1), aloe-emodin (2), kaempferol (3), 29-nonacosanolide (4), 1-octadecanol (5), beta-sitosterol (6).
Conclusion:
Compounds 2, 4, 5 are isolated from this plant for the first time.
