| Abstract: | In this study,a new spectrophotometric method had been developed to detect L-carnitine in the milk powder by optimizing the react conditions.The experimental results demonstrate that The absorbtion of the solution had a direct relationship with the L-carnitine concentration in the range of 2.1～22.0ug/mL.The revovery of the method was in the range of 97.6%～99.0% and the RSD was 0.2%（n=7）.The proposed method owns the advantages of easy-operation,rapid,high accuracy and good precision. |
| Keywords: | spectrophotometry milk powder L-carnitine |
