金龙胶囊氨基酸类成分指纹图谱的建立

摘要

目的：建立金龙胶囊氨基酸类成分指纹图谱。方法采用6-氨基喹啉基-N-羟基琥珀酰亚氨基甲酸酯(AQC)进行柱前衍生化,超高效液相色谱法同时测定制剂中17种氨基酸,建立金龙胶囊氨基酸类成分指纹图谱。结果共标出22个共有峰,鉴定出17种氨基酸,10批样品相似度均＞0.9。结论所建立的金龙胶囊氨基酸类成分指纹图谱特征性强,可以作为金龙胶囊质量控制的手段之一。%Objective To establish the fingerprint of amino acids composition of Jinlong capsule. Methods Using 6-acetamido-4-hydroxy-2-methyl quinoline (AQC) as the derivating agent, 17 kinds of amino acids were analyzed by UPLC at the same time and the fingerprint of amino acids composition of Jinlong capsule was established. Result Totally 22 co-possessing peaks were selected as the fingerprint peaks, 17 kinds of amino acids were identified. The fingerprint similarity value of 10 batches was above 0.9. Conclusion The fingerprint is characteristic and can be used for the quality control of Jinlong capsule.
