Summary
A rapid separation of citrus carotenoid pigments is achieved by successive thin-layer chromatographic separations on two different adsorbents. The first chromatography on silica gel G developed with the solvent system acetone-petroleum ether (30∶70) gives a preliminary fractionation into groups with different polarity (hydrocarbons, monols, diols and polyols). A further separation of each group into individual carotenoids is obtained by rechromatography on MgO-Kieselguhr (1∶1, w/w). The same solvent system is used, the acetone percentage being increased according to the polarity of each group (from 4% to 30%).
