Abstract

Objective: To study the chemical constituents form stem bark of Wikstroemia indica.

Method: The constituents were isolated by column chromatography on silica gel and ODS, and identified by spectroscopic methods.

Result: Seven compounds, daphnoretin (I), tricin (II), daucosterol (III), beta-sitosterol (IV), umbelliferone (V), genkwanin (VI), and 6'-hydroxy, 7-O-7'-dicoumarin (VII), were isolated and identified.

Conclusion: Compound VII was a new compound and compounds III, V were isolated from this plant for the first time.
