Abstract:
Fifteen batches of Glycyrrhizeae Radix standard decoction were prepared for determination of the content of the glycyrrhizic acid and liquiritin, then the transfer rate and the extract rate were calculated and a method was established to analyze the fingerprint by HPLC. According to the measurement of 15 batches of samples,the transfer rate of the glycyrrhizic acid and liquiritin were 59.4%-87.4% and 49.8%-78.9% with extract rate of 29.9%-38.9%. Moreover,10 common chromatographic peaks were determined based on their fingerprint by using similarity evaluation system for chromatographic fingerprint of traditional Chinese medicine (TCM)(2012A) .The similarity results of 15 batches of samples were analyzed and compared,and the results showed that the similarity was all higher than 0.9. Fifteen batches of samples,prepared by a standard method,have stable quality and the high similarity.The method displayed good precision,stability and repeatability in fingerprint analysis. Therefore,this study can provide a reference for the quality control of Glycyrrhizae Radix dispensing granules.
