[Studies on the chemical constituents of Wikstroemia indica].

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).

CONCLUSIONS

Compounds 2, 4, 5 are isolated from this plant for the first time.
