Comparision on Carotenoid Compositions and Contents in Different Sweet Pomelos

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.
