Notes:
A procedure for the quantitative estimation of provitamin A carotenoids beta-carotene, cryptoxanthin and cryptoxanthin esters in some fruits using conventional column and high performance liquid chromatography was developed. The provitamin A carotenoids were first separated by column chromatography on alumina prior to furthur separation and quantitation by reversed phase liquid chromatography. The distribution of provitamin A carotenoids in fruits varied. Among the provitamin A rich fruits, apricot, mango, and cantaloupe contained essentially beta-carotene whereas cryptoxanthin accounted for nearly half the total carotenoids in papaya, persimmon, and tangerine. Peach, red bell papper, oranges and red grapefruits were intermediate in their provitamin A content while tomato, yellow bell pepper, pineapple and watermelon were poor sources. Cryptoxanthin occurred acylated with C8 to C18 saturated fatty acids in the fruits analyzed.
