Carotenoid Contents in Different Millets Cultivars Collected from China and Korea

초록

Millet (Panicum miliaceum L.) cultivars from China and, Korea were analyzed-using HPLC to determine the levels of 5-different Carotenoids: zeaxanthin, beta-carotene, 9-cis-beta-carotene and 13-cis-beta-carotene. There was a significant difference in carotenoid content among cultivars from the 2 locations, with the Chinese cultivars generally having a higher content than the Korean cultivar. Lutein was present at The highest concentration in all of the cultivars, but was 34, 33 and 16 % higher in Joongback (China), than in Joongjukyumi (China),,Hwanggnem (Korea) and Joongjuk (China), respectively. Thongback also contained 58, 55 and 37 % higher Concentrations of zeaxanthin than Joongjukyumi, Hwangguem and Joongjuk, respectively and a 33 % higher concentration of beta-carotene than Hwangguem (Korea), The-other two,Carotenoids (9-cis-beta-carotene and 1:3-cis-beta-carotene) were present:at similar levels mall 4 cultivars. The results suggest that the millet cultivar Joongback from China could potentially be used as a source of carotenoids in the human diet.
