PREPARATIVE SEPARATION OF β-SITOSTEROL BY HIGH SPEED COUNTERCURRENT CHROMATOGRAPHY
Journal of Liquid Chromatography & Related Technologies, 2002β-sitosterol was successfully separated and purified from both β-sitosterol standard (about 60% purity) and crude sterols using high-speed countercurrent chromatography (HSCCC) with a heptane–aceto...

[Separation of isomeric compounds by high speed countercurrent chromatography].
Se pu = Chinese journal of chromatography, 2010High speed countercurrent chromatography (HSCCC) was successfully used for the separation and preparation of isomeric compounds. The influence of various two-phase solvent systems on the resolution of the natural catechin isomers of (-) -epigallocatechin gallate (EGCG) and (-) -gallocatechin gallate (GCG) from green tea polyphenols and the synthetic ...
