摘要
利用色氨酸结构中的吲哚基团在酸性条件下与对二甲氨基苯甲醛的特殊反应 ,在 6 10nm处测定复合氨基酸注射液中L 色氨酸的含量 。
The content of tryptophan in the complex amino acid injection was determined with spectrophotometer at 610 nm after reaction between the indole group of tryptophan and p dimethyl amino benzaldehyde under acidic condition. The method was approved to be satisfactory.
