Evaluation of Some Carotenoids in Grapes by Reversed- and Normal-Phase Liquid Chromatography: A Qualitative Analysis

Carotenoids in grapes of three Port winemaking cultivars were investigated. Extracts were obtained with n-hexane/diethyl ether mixtures (0/100; 20/80; 50/50; 100/0) and analyzed by normal and reversed phase HPLC-DAD. Selection and identification of peaks were based on spectroscopic characteristics −...
