Abstract
OBJECTIVE: To study the chemical constituents from Lithocarpus polystachyus. METHODS: Compounds were isolated and purified with silica gel, and there structures were identified by chemical property and spectral data. RESULTS: Nine compounds were isolated as phloridzin (I), phloretin (II), dihydrochalcone-2'-beta-D-glucopyranoside (III), daucossterol (IV), beta-sitosterol (V), quercetin (VI), luteolin (VII), quercitrin (VI), oleanolic acid (IX). CONCLUSION: Compounds II, IV - IX are isolated from this plant for the first time.
