采用HPLC技术对果肉色泽不同的黄金蜜柚、红肉蜜柚、琯溪蜜柚的类胡萝卜素的组成及含量进行比较分析。结果表明,黄金蜜柚汁胞呈色成分主要为β-胡萝卜素、八氢番茄红素、α-胡萝卜素、β-隐黄质和番茄红素,含量分别为218.83、22.95、4.17、2.96、2.86μg·g-1,类胡萝卜素总量达到251.77μg·g-1·dw-1,分别是红肉蜜柚和琯溪蜜柚的2.6倍和287.7倍。
Abstract:
The carotenoid contents and compositions of sweet pomelos with different fresh colors,including huangjin sweet pomelo, red-fleshed sweet pomelo and guanxi sweet pomelo, were identified by using HPLC. The results showed that carotenoids were mainly made up of β-carotene,phytoene, α-carotene, β-cryptoxanthin and lycopene, and the contents were 218.83, 22.95, 4.17, 2.96 and 2.86 μg·g-1·dw-1, respectively. The total content of carotenes in flesh of huangjin sweet pomelo reached up to 251.77 μg·g-1·dw-1, 2.6 times of that in red-fleshed sweet pomelo and 287.7 times of that in guanxi sweet pomelo.
