摘要

The all-liquid chromatographic techniques of high-speed countercurrent chromatography (HSCCC) and multilayer coil countercurrent chromatography (MLCCC) were applied for isolation of flavonol glycosides from tea, shallot and endive, as well as anthocyanins from fruit juices and purple carrot. CCC also allowed the isolation of preparative amounts of the anti-HIV agent chicoric acid from endive. In addition, polymeric pigments from red wine and black tea could be isolated and fractionated by HSCCC and centrifugal precipitation chromatography (CPC). Subsequent LC-MS analyses of separated HSCCC-fractions revealed partial resolution of the complex mixture of tea polyphenols.
