Separation and Assay. H.p.l.c. methods have been described for the determination of chloroplast pigments,phytoplankton pigments,and provitamin A carotenoids in tomatoes.Other chromatographic procedures have been devised for the separation of Capsicum carotenoids and chloroplast pigments from tobacco mutants, " and methods for the high-speed video-densitometric determination of carotenoids separated by t.l.c., and for the dual assay of carotenoids and vitamin A in human liver have been reported. H.p.l.c. has been used for the separation of cis-trans-isomers of retinal, retinol and retinyl... 

Carotenoids are synthesised de novo by all photosynthetic organisms including higher plants, phytoplankton and phototrophic bacteria as well as by certain other bacteria, yeasts and fungi. Carotenoids are selectively absorbed and metabolically modified in the food chain [17]. Animals cannot synthesise carotenoids de novo, but may contain specific carotenoids derived from dietary sources.
