ABSTRACT
Objective:
To establish a method for detecting the content of vitamin B2 in Weimeisu tablets by HPLC-FLD.Methods:
A PAK C18(250 mmID × 4. 6 mm,5 μm) column was employed with methanol -0. 02 mol·L-1 ammonium acetate (35∶65) as the mobile phase, the flow rate was 1. 0 ml·min-1, and the injection volume was 10 μl. The detection wavelength λex and λem were 450mn and 522 mn, respectively.Results:
Vitamin B2 was linear within the range of 1.0-20 μg·ml-1(r=0.999 9). The average recovery was 99. 20%(RSD=0. 63%, n=6).Conclusion:
The method is specific, sensitive and accurate, and can be used to deter-mine vitamin B2 in Weimeisu tablets.
