| Abstract: | An HPLC method for determination of Vitamin B and caffeine in health foods was described. Vitamin B1 was detected at 260 nm based on: methyl/distilled water/phosphoric acid(100/400/0.5) as extraction and sodium dodecylsulfate/acetonitrile/phosphoric acid(530/470/1) as mobile phases. Vitamin B6, caffeine, niacin and niacinamide were examined at 280 nm with sodium 1-decanesulfonate/acetonitrile/phosphoric acid(850/150/1) as mobile phase. It is concluded that this method is suitable for rapid and accurate analysis of Vitamin B and caffeine in health foods.
