摘要: The objective of this study was to compare the carotenoid composition of sweet and waxy corn grains at the stage of milk and dough by reversed-phase high-performance liquid chromatography, using a C(30) column, connected to diode array detector and mass spectrometry. In the reverse phase 21 carotenoids were found, the major identified carotenoids were all-trans-lutein, all-trans-zeaxanthin, and all-trans-- cryptoxanthin. Waxy corn grains showed significantly lower contents for total carotenoids ranging from 1.52 to 3.68 g/g dry weight in three varieties, whereas sweet corn grains had higher carotenoid contents from 8.42 to 39.71 g/g dry weight. The composition of the carotenoid pattern was somewhat different compared to literature data; this could be the results of genetic or environmental differences. Taking into account the usage of all-trans lutein and all-trans-zeaxanthin for the prevention of several pathologies, especially the age related macular degeneration, the immature sweet corn (e.g., Jingtian 5 and Jingtian 3) might be interesting sources of a lutein and/or zeaxanthin extract that could add value to an underutilized biomass.
