摘要： A reversed-phase high performance liquid chromatographic method for the simultaneous determination ofvitamin A and D_2 in fortified milk has been developed. A couple of serially connected columns with μ-Bonda-pak C_(18)(300 × 3. 9mm, 10μm)and Novapak C_(18)(150 × 3. 9mm, 4μm)and methanol/water(96/4)mobile phasewere used. Vitamin A and D_2 were detected at wavelengths of 325nm and 265nm, respectively. By usingsaponification procedure, the recoveries of vitamin A and D_2 were in the range of 90～110%.
