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.
已开发出一种定量方法,用于测定橙汁中的维生素A原类胡萝卜素α-胡萝卜素、β-胡萝卜素和β-隐黄质。类胡萝卜素通过高效液相色谱法在一根柱子上于约30分钟内分离。该方法也可用于测定ζ-胡萝卜素和α-隐黄质。
