Determination of Nine Kinds of Vitamin B Components in Healthy Food Vitamin B Tablets by HPLC

  • Objective: To establish a method for the determination of nine vitamin B components in vitamin B tablets by high performance liquid chromatography-diode array detector (HPLC-DAD). Method: Folic acid was ultrasonically extracted with 0.3% ammonia solution, biotin, vitamin B12 and pantothenate acid were ultrasonically extracted with water, the vitamins B1, B2, B6, niacin and nicotinamide were ultrasonically extracted by 0.1% hydrochloric acid, separated by C18 column with methanol-0.1 mol/L potassium dihydrogen phosphate solution as the mobile phase for gradient elution. Pantothenate acid and biotin were detected at the wavelength of 205 nm, vitamins B1, B2, niacin and nicotinamide were detected at the wavelength of 256 nm, vitamins B6 and folic acid were detected at the wavelength of 287 nm, vitamins B12 was detected at the wavelength of 361 nm. Results: The results showed that the nine components could be separated well, and the linear relationship was good in their linear range. The average recoveries were 91.8%~106.9%, RSD were 0.2%~4.8%, and the detection limit of the method were 0.05~4.7 mg/kg. Conclusion: This method is rapid, simple, accurate and repeatable. It can quickly complete the determination of nine vitamin B components in health food vitamin B tablets and reduce the cost.
