High-speed counter-current chromatography (HSCCC) is a new and high efficiency form of liquid-liquid partition chromatography, which was developed by the Dr Yoichiro Ito of national sanitation academe of USA in 1982. Compared with conventional chromatographic methods, HSCCC does not use any solid matrix.Therefore it eliminates irreversible adsorption, decomposition, contamination and many other disadvantages owing to chemical reactions of samples with solid support. In addition, it has many advan...
