[Application of quantitative fingerprint to amino acids composition analysis of Xingnao Tongluo injection]
Objective:
To control the quality of the product, quantitative fingerprint was used to evaluate the composition of the amino acids in the Xingnao Tongluo injection.
Method:
The method of the quantitative fingerprint to the amino acids composition was established through AccQ Tag precolumn derivatization. The quality was evaluated by the quantitative test of the amino acids and the similarity in ten batches.
Result:
The Xingnao Tongluo injection contained 12 amino acids and the contents of these amino acids were stable. All the ten batches of the samples had similarity of more than 0.90.
Conclusion:
The method was accurate, feasible and could be a simple and effective way to evaluate the quality of the traditional Chinese medicine.
