| 摘 要： | 17种复合氨基酸注射液中,L-色氨酸、L-苯丙氨酸与 L-酪氨酸的紫外吸收光谱完全重叠,且配方中三者吸收度相差甚大。本文采用三阶导数光谱法(光法、电法)和系数倍率法,试样不经分离,稀释一次后直接测定。回收率及变异系数分别为100.61%,0.2986%;98.73%,1.0508%;97.38%,2.3017%。

| Abstract: | The ultra-violet spectra of L-tryptophan,L-phenylalanine,andL-tyrosine in compound amino acids injection(17)were studied.The sample wasdiluted with water and analyzed by its third order derivative spectrum and bymultiplying factor spectrophotometry.The percent recoveries and cv of theseamino acids were 100.61%,0.2986%;98.73%,1.0508%;97.38%,2.3017%,respec-tively. |
