Sugarcane rind contains some functional phenolic acids. The separation of these compounds from sugarcane rind is able to realize the integrated utilization of the crop and reduce environment pollution. In this paper, a novel protocol based on interfacing online solid-phase extraction with high-speed counter-current chromatography (HSCCC) was established,(More)
Chlorogenic acid and caffeic acid were selected as test samples for separation by the pH-zone-refining countercurrent chromatography (CCC). The separation of these test samples was performed with a two-phase solvent system composed of methyl-tert-butyl-ether/acetonitrile/water at a volume ratio of 4:1:5 v/v/v where trifluoroacetic acid (TFA; 8 mM) was added(More)
pH-zone-refining counter-current chromatography technique for the separation of natural and synthetic mixtures has been widely used, especially for organic acids and alkaloids. Phenolic acids are very important compounds due to the potential treatment for a wide variety of diseases. However, there is not a general method for their separation. In this work,(More)
