| Abstract: | OBJECTIVE To establish a method for determination of vitamin B 2 in the tablet of vitamin B complex. METHOD Diffuse reflectance FTIR was used for determination of vitamin B 2.RESULTS The content of vitamin B 2 could be detected directly,and the relationship between the absorbance and the concentration was linear. The average recovery of vitamin B 2 was 99.79%,and RSD was 1.85%.CONCLUSION The method is simple,fast and reliable;it has been proved to be a good practice for determination of vitamin B 2 in the tablet of vitamin B complex. |
