A method is presented for measurement of Vitamin A in food composites by high speed liquid chromatography. Saponification of the sample is necessary, but no purification or separation is required. Neither phytofluene nor other unsaponifiable material in the sample cause interference. Accurate measurement is possible in samples which contain 0.5–4 μg/ml, and recovery of Vitamin A standard in the presence of high levels of carotenoids is 103.5%.
