Abstract pH-Zone-refining countercurrent chromatography was successfully applied to the separation of salvianolic acid B from the Chinese medicinal plant, Salvia miltiorrhiza Bunge, using a multilayer coil. planet centrifuge. A 2.0 g quantity of sample was separated using the following two-phase solvent system: methyl tert-butyl ether (MtBE)water, 10 mM TFA in organic stationary phase and 10 mM ammonia in aqueous mobile phase. The obtained fractions were analyzed by HPLC and ESI-MS. The separation yielded 572 mg of the main component of salvianolic acid B with a purity of 94.1%.
