To study the chemical constituents of the roots of Euphorbia soongarica (Xinjiang origin).
METHODS
Compounds were isolated and purified by repeated normal column chromatography, preparative thin layer chromatography and Sephadex LH - 20 chromatography. The chemical structures were
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
Successive purification of the extract from Canarium album and Euphorbia nematocypha, guided by antihepatotoxic activity in primary cultured rat hepatocytes, led to the isolation of brevifolin (1), hyperin (2), ellagic acid (3) and 3,3'-di-O-methylellagic acid (4) as hepatoprotective compounds.
