摘要
The carotenoid compositions of the peel and the pulp of various citrus fruits were compared with HPLC methods using C 18 and C30 columns. The extracts usually contain beta-cryptoxanthin and lutein in considerable amounts and in all species except lime, the red apocarotenoid beta-citraurin as well. In case of lime and mandarin the carotenoid compositions of peel and pulp show a good coincidence while in orange, clementine, grapefruit, lemon and kumquat there are a lot more differences. Lime extracts contain practically only two carotenoids: beta-carotene and lutein. The carotenoid components of the saponified extracts of kumquat were separated on calcium carbonate columns and were investigated in detail. The components were identified with HPLC-DAD and HPLC-MS.
