目的 进行不同来源苗药黑骨藤抗类风湿性关节炎有效部位中新绿原酸、绿原酸、隐绿原酸、异绿原酸B，异绿原酸A、异绿原酸C 6种咖啡酰基奎宁酸类化学成分测定并结合化学计量学综合分析其质量，为合理有效评价苗药黑骨藤抗类风湿性关节炎功效提供依据。方法 采用HPLC-UV法同时测定，色谱柱为Xtimate C18（250 mm×4.6 mm，5 μm），流动相为0.1%甲酸水-乙腈，梯度洗脱，进样量10 μL，体积流量1 mL/min，柱温25℃，检测波长327 nm；采用SPSS24.0及SIMCA14.1软件进行综合分析评价黑骨藤药材的质量。结果 对21批不同来源黑骨藤样品进行了含量测定；通过聚类分析，将21批样品分为Ⅲ类，其中第Ⅱ和第Ⅲ类质量较好；主成分分析和偏最小二乘判别分析结果与聚类结果一致，筛选得到绿原酸和异绿原酸C是引起不同来源黑骨藤质量差异的标志物。结论 通过对6种咖啡酰基奎宁酸类成分含量测定结合化学计量法，可以进一步针对黑骨藤抗类风湿性关节炎的功效品质进行评价，为黑骨藤质量控制提供参考依据。
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.
