Abstract:Objective :To determine Vitamin B6 in Naoluotong Capsules by HPLC. Methods: Hypersill BDS Cis 5 μm, 0. 5% Potassium dihydrogen phosphate-methanol-triethylamine (85: 14. 5: 0. 5) as mobile phase. The flow rate was 1 mL· min^-1, the detection wavelength was 290nm. Results: The calibration curve was linear in the rang of 0. 646-2. 582 μg for Vitamin B6 (r =0. 999 9). The average recovery (n =6) was 100. 16%. Conclusion: The method is rapid, accurate and reliable,and the method may be used as a standard for Naoluotong Capsules.
Keywords:HPLC  Vitamin B6  Naoluotong Capsules
