The application of membrane technologies as well as countercurrent chromatography (CCC) for the large-scale fractionation of polyphenolic extracts will be demonstrated. CCC is a support-free liquid liquid chromatographic technique which allows gentle separations in the g to kg scale. Techniques that will be presented include inter alia high-speed countercurrent chromatography (HSCCC) and spiral-coil low speed rotary countercurrent chromatography (Spiral-coil LSRCCC). Examples are the preparation of bioactive compounds (anthocyanins, OPC, stilbenes etc.) from side streams of the wine industry.
