THIN-LAYER CHROMATOGRAPHY OF NATURAL PIGMENTS: NEW ADVANCES

Abstract

ABSTRACT The newest achievements in the use of thin-Layer chromatography (TLC) for the separation and quantitative determination of natural pigments in various matrices are assembled. The techniques applied for the analysis of individual pigments and pigment classes (anthocyanins, flavonoids, carotenoids, and other pigment classes) are surveyed, critically evaluated, and the advantages and disadvantages of the individual methods are discussed in detail. Future trends in the separation and identification of pigments by TLC are delineated.
