Abstract:
Objective: To establish HPLC fingerprint of Notopterygii Rhizoma et Radix with different commercial specifications and to provide the basis for the division of commercial grades and the quality control of Notopterygii Rhizoma et Radix on the market. Method: The market investigation and literature research were used to understand the existing situation of Notopterygii Rhizoma et Radix goods.Notopterygii Rhizoma et Radix goods were divided into three commercial specifications according to the source and appearance,such as Canqiang,Tiaoqiang and Datouqiang.Fingerprint of Notopterygii Rhizoma et Radix with different commercial specifications was established by HPLC-PDA,the mobile phase was consisted of acetonitrile-0.3% acetic acid in a gradient elution mode.Similarity evaluation system for chromatographic fingerprint of traditional Chinese medicine(version of 2004A) was used to confirm the common peaks and evaluate the similarity.SPSS 19.0 statistical software was used to make principal component analysis(PCA) for HPLC fingerprint pattern. Result: The common mode of fingerprint for Canqiang,Tiaoqiang and Datouqiang were established separately.A total of 22 common peaks were marked in Canqiang,23 common peaks were marked in Tiaoqiang,29 common peaks were marked in Datouqiang.The result of similarity evaluation and PCA showed that the quality of Notopterygii Rhizoma et Radix with the same commercial specification was stable.There were great differences in chemical compositions and their contents among Notopterygii Rhizoma et Radix with different commercial specifications. Conclusion: The fingerprint method can well distinguish commercial specifications of Notopterygii Rhizoma et Radix,and it can provide the basis for the division of commercial grades and the quality control of Notopterygii Rhizoma et Radix.
