Abstract:
Objective: To establish and analyze the HPLC characteristic chromatogram for water extracts of Arisaematis Rhizoma (AR) and its processed products, Arisaematis Rhizoma Preparatum (ARP) and Arisaema Cum Bile (ACB). The research provided reliable method and scientific basis for their quality control. Methods: The separation was performed on an Agilent C18 (200 mm × 4.6 mm, 5 μm) column with gradient elution of 0.2% acetic acid water and 0.2% acetic acid acetonitrile. The similarity was analyzed with software “Similarity Evaluation System for Chromatographic Fingerprint of TCMs (Version 2012)”. The cluster analysis was performed by SPSS 23.0. The principal component analysis was performed by SIMCA 14.1. Results: HPLC characteristic chromatogram for water extracts of AR, ARP, and ACB were established. There were 19, 20 and 13 common peaks in AR, ARP and ACB, respectively. A total of eight characteristic peaks were identified as F1 (xanthine), F3 (uracil), F4 (hypoxanthine), F5 (uridine), F6 (guanosine), F7 (adenosine), F14 (schaftoside), and F16 (isoschaftoside), respectively. The intragroup similarities of AR, ARP, and ACB were all above 0.8 and each was clustered into one type, and the intergroup similarities among AR and its processed products were all below 0.4. The main components of AR were F16 (isoschaftoside), F14 (schaftoside), F17and F15. The main components of ARP were F16 (isoschaftoside) and F1 (xanthine). The main components of ACB were F3 (uracil), F2, F5 (uridine) and F1 (xanthine). Conclusion: The method can effectively identify AR, ARP and ACB, and provide a scientific basis for their quality control.
