摘要:

建立超高效液相色谱-串联质谱同时测定金银花中9种主要成分的方法。采用负离子扫描方式,对主要成分进行化学计量学分析。色谱分离采用 Thermo Hypersil GOLD 色谱柱,柱温35 ℃。流动相由甲醇和 0.2% 甲酸水溶液组成,结合聚类热图分析和主成分分析对金银花进行综合分析。结果表明: 9个化合物峰面积与浓度之间具有良好的线性关系(R2>0.999 1),日内精密度(0.96%~2.26%)、日间精密度(0.52%~3.04%)和稳定性(0.85%~2.15%)均符合相对标准偏差;回收率在96.77%~101.94%之间,相对标准偏差在2.48%~4.01%之间;层次聚类分析和主成分分析在内的化学计量学结果表明,不同地区的金银花活性成分含量存在明显差异,3-O-咖啡酰奎宁酸和3,5-二咖啡酰奎宁酸为贡献最大的化合物。该研究可为进一步开展金银花有效成分及相关量效关系、相关产品的质量控制提供参考。

Abstract:

This study aimed to devise a methodology for the simultaneous determination of the contents of nine primary components in Lonicerae japonicae flos through ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The chemometric analysis of the nine primary components was performed via negative ion scanning. Further, chromatographic separation was performed on a Thermo Hypersil GOLD column at a temperature of 35 ℃. The mobile phase comprised methanol and water containing 0.2% formic acid, as determined through the cluster thermogram and principal component analyses of Lonicerae japonicae flos. The peak areas with concentrations of nine components exhibited a good linear relationship (R2>0.999 1), and the intraday (0.96%~2.26%) and interday (0.52%~3.04%) precisions and stability values (0.85%~2.15%) agreed well with relative standard deviation (RSD). The recovery rate was between 96.77% and 101.94%, and the RSD was between 2.48% and 4.01%. The results of the chemometric, hierarchical cluster, and principal component analyses revealed that there were considerable differences in the contents of the active ingredients of Lonicerae Japonicae Flos from various regions, and 3-O-caffeoylquinic acid and 3,5-dicaffeoylquinic acid were considered as the dominant compounds. UPLC-MS/MS quantitative and chemometric analyses of Lonicerae Japonicae Flos performed herein may provide a reference for the modernization of and innovative research on the effective ingredients of Lonicerae Japonicae Flos and related quantity effect relations as well as the quality control of related products.
