ABSTRACT
Vitamin classification is initially based on fat solubility-i.e., A, D, E, and K-versus water solubility-i.e., C, folic acid, nicotinic acid, and nicotinamide (B3), B1, B2, B6, biotin, B12, and pantothenic acid. DeLeenheer et al. (1985, 1992) edited two valuable treatises on modern chromatographic analysis of vitamins. Two tables have been compiled in this chapter with information on the chemical terms for vitamins and their derivatives, vitamin function, sources of vitamins and recent selected references containing TLC information. Table 19.1 summarizes pertinent information on the fatsoluble vitamins and Table 19.2 does the same for the water-soluble vitamins.
