ABSTRACT
Objective:
To investigate the effects of neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, isochlorogenic acid B, isochlorogenic acid A, and isochlorogenic acid C in effective parts of rhizoma arthritis against rhizoma arthritis from different sources of Miao medicine Periploca forrestii Schltr. The determination of 6 kinds of caffeoacylquinic acid chemical components and comprehensive analysis of their quality combined with chemometrics provide a basis for a reasonable and effective evaluation of the efficacy of Miao Medicine Periploca forrestii Schltr against rheumatoid arthritis.Methods:
Simultaneous determination was performed by HPLC-UV method. The column was Xtimate C18 (250 mm×4.6 mm, 5 μm), the mobile phase was 0.1% formic acid-acetonitrile, gradient elution, the injection volume was 10 μL, and the flow rate was 1 mL/min. The column temperature is 25 ℃ and the detection wavelength is 327 nm. SPSS24.0 and SIMCA14.1 software are used for comprehensive analysis and evaluation of the quality of medicinal materials.Results:
The content of 21 batches of Periploca forrestii Schltr samples from different sources was determined. Through the cluster analysis, the 21 batches of samples were classified into type III, of which the quality of types II and III was better; principal component analysis and partial least squares discriminant analysis The results were consistent with the clustering results. The chlorogenic acid and isochlorogenic acid C were screened to be the markers that caused the differences in the quality of Periploca forrestii Schltr from different sources. Conclusion The determination of the contents of six caffeoacylquinic acid components combined with stoichiometry can further evaluate the efficacy and quality of the anti-rheumatoid arthritis effect of Periploca forrestii Schltr, and provide a reference basis for the quality control of Periploca forrestii Schltr.
