Chemical Constituents of Wikstroemia Indica

OBJECTIVE To study the chemical constitutents from Wikstroemia indica (L.) C. A. Mey. METHODS Silica gel column, Sephadex LH-20 column chromatography were used for separation and purification of the compounds and extensive spectral analysis spectrum were employed for structural elucidation. RESULTS Nine compounds were isolated from EtOAc and n-butanol fraction of the 85% ethanol extract of the W. indica and identified as daphnoretin, naringin, 3,5,7-trihydroxy-4′-methoxy-dihydroflavonol, 4-hydroxybenzoic acid, benzoic-acid, umbdheforne, daphnogitin, sikokianin B, and genkwanin. CONCLUSION Compounds 2-5 are obtained from the plants of W. indica for the first time.
