Abstract: cf. C.A. 53, 15417i. The changes of the coloring matter of 'spicy' paprika during aging were studied by adsorption paper chromatography on Whatman 3 paper with benzene-96% EtOH (25:0.4) as solvent. β-Carotene and isomer of β-carotene, cryptoxanthin, xanthophyll, zeaxanthin, flavoxanthin, capsorubin, and capsanthin were identified. The extinction was measured by Pulfrich's photocolorimeter with 'S 47' filter. During the natural wilting of paprika all coloring matter increased with a synthesis of carotenoids.
