Abstract:
An optimized method for large‐scale preparative separation of polyhydroxystilbenes (PHS) from the rhizome of Rheum likiangense Sam. by high‐speed counter‐current chromatography (HSCCC) has been established in this paper. Eighty‐four milligrams of desoxyrhaponticin with 98.2% purity and 148 mg of rhaponticin with 95.3% purity were respectively yielded from 1.5 g of crude extract in the single one‐step HSCCC operation within 440 min using a solvent system consisting of methanol:n‐butanol:chloroform:water (2:0.5:3:3, v/v/v/v).
