Reverse-phase. high-performance liquid chromatography was used for the simultaneous determination of retinol, a-tocopherol, lycopene, a-carotene, and &carotene in human plasma. A multiple solvent system of methanol followed by a mixture of metbanol:acetonitrile:chloroform (47:42: 11) provided clear
In this report we describe a modified reverse phase HPLC method that avoids the solvent evaporation step and allows simple and rapid determination of retinol, alpha-tocopherol, alpha-carotene and beta-carotene and achieves complete separation of alpha- and beta-carotene. Retinyl acetate, alpha-tocop
