| Abstract: | An fast method was developed to simultaneously detect the content of niacinamide, caffeine, vitamin B6, tartrazine, carmine and benzoic acid in functional beverage by HPLC. The limits of detection (LOD) of niacinamide, caffeine, vitamin B6, tartrazine, carmine and benzoic acid were 0.1, 0.1, 0.2, 0.2, 0.1, 0.1 mg/L, respectively. The relative standard deviations were not more than 4.57%(n=6), and the recoveries ranged from 95.80% to 113.68%. The method was suitable for the demand of LOD of niacinamide, caffeine, vitamin B6, tartrazine, carmine and benzoic acid from GB/T 5009.197-2003, GB/T 23495-2009 and SN/T 2105-2008. |
