| Abstract: | Objectives and Methods:The content of Trytophane in compound capsule which contain nine kinds of amino acid and four kinds of vitamin was determined directly by 4st detervative spectrum. Results:The interference of other components can be eliminated.The correlation coefficient of the standard curve r =0.9993,the average recovery was 102.04 %,and RSD=0.45%. Conclusions:The method is simple and accurate,and the samples are not need to be isolated. |
