[Studies on the chemical constituents of Wikstroemia indica].

To study the chemical constituents of Wikstroemia indica. The constituents were isolated and purified by silica gel chromatography repeatedly, and the structures were determined by spectral data and chemical envidance. 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). Compounds 2, 4, 5 are isolated from this plant for the first time.
