Determination Optimization of Total Amino Acids in Runing Pills by Orthogonal Design / 中国药师

Objective:To optimize the determination technology for the total amino acids in Runing pills. Methods:The process was optimized by L9 (34 ) orthogonal design using the hydrolysis temperature, hydrolysis time and hydrochloric acid concentration as the evaluation factors,and the content and yield of total amino acids as the evaluation indices. Results: The optimal determination condi-tions were as follows:the hydrolysis temperature was 110℃, the hydrolysis time was 22 h and the hydrochloric acid concentration was 6 mol·L-1 . Conclusion:The optimal determination technology can be applied in the total amino acids from Runing pills,which pro-vides the basis for the further research of Runing pills.
