Countercurrent chromatography of black tea infusions



Countercurrent chromatography of black tea infusions



Journal of Chromatography 505(2): 357-364



Counter-current chromatography using a multilayer coil planet centrifuge with solvent system ethyl acetate-butanol-water, permits the separation of black tea infusions into fractions which include per SII and a mixture of SI and SIa thearubigins. Good resolution of several components of the infusion may be achieved in elution times of 1 to 2 h. The appearance of chromatograms is altered on decaffeinating the infusion. The effect of stationary phase composition is considered. Resolution of the peaks improves with butanol content.
