Abstract
The investigation on the herbal of Euphorbia humifusa Wild. was carried out to find its anti-HBV constituents. The isolation and purification were performed by chromatography such as macroporous resin, polyamide, Sephadex LH-20, MCI GEL CHP 20P and so on. Based on the spectral analysis, seven phenols were identified as brevifolin (1), brevifolin carboxylic acid (2), methyl brevifolincarboxylate (3), phyllanthussin E methyl ester (4), sanguisorbic acid dilactone (5), 3,3'-2-di-O-methyl ellagic acid (6), ellagic acid (7). Among them, Compounds 2-6 were isolated from this plant for the first time.
