A mixture of nicotinic acid, nicotinamide, trigonelline and tryptophan can be separated chromatographicaUy, using as solvent a 5 i mixture of n-butanol and concentrated hydrochloric acid, saturated with water. Tryptophan is revealed by ninhydrin, while nicotinic acid, nicotinamide and trigonelline are detected with phosphomolybdic acid reagent and the color developed with stannous chloride, which reduces the phosphomolybdic acid to give a blue spot. The Rf values for the butanol-HCl solvent are nicotinic acid, 0.37 nicotinamide, 0.28 trigonelline, 0.38 and tryptophan, 0.62. [Pg.51]
