High performance liquid chromatographic determination of provitamin A in orange juice.
A quantitative method has been developed for the determination of alpha- and beta-carotenes and beta-cryptoxanthin, the provitamin A carotenoids in orange juice. The carotenoids were separated by high performance liquid chromatography on a single column in approximately 30 min. The procedure may also be used to measure zeta-carotene and alpha-cryptoxanthin.
