摘要
目的:建立一种固相萃取-高效液相色谱-电喷雾串联质谱(SPE-HPLC-ESI-MSn)分析方法,对清火栀麦片中主要的化学成分进行快速识别与鉴定。方法:根据HPLC-ESI-MSn负离子模式下的分子离子峰以及碎片离子获得化合物的结构信息,并通过与文献数据或对照品对照,确定化合物可能的结构。结果:通过对清火栀麦片及其组方药味进行比较分析,归属并鉴定了其中的39个化学成分,包括7个咖啡酰奎尼酸、7个环烯醚萜、6个二萜内酯、5个高异黄酮、13个甾体皂苷以及1个黄酮类成分。结论:该研究为鉴别清火栀麦片中的化学成分提供了一种简便、快速的方法。
Objective: To establish a method for analyzing solid phase extraction-high performance liquid chromatography-elec- trospray ionization tandem mass spectrometry ( SPE-HPLC-ESI-MSa ), in order to recognize and identify the main chemical constituents in Qinghuo Zhimai tablets. Method : The possible structures of the compounds were determined according to the structure information of compounds observed from molecular ion peaks and fragment ions in HPLC-ESI-MSn negative ion mode and by comparing with literature data or control samples. Result: Through the comparative analysis on Qinghuo Zhimai Tablets and components of its formula, 39 chemi- cal constituents were identified, including 7 caffeoylquinic acids, 7 iridoids, 6 diterpenoid lactones, 5 homoisofiavonoids, 13 steroidal saponins and 1 flavone glycoside. Conclusion: This study provides a simple and rapid method for identifying chemical components in Qinghuo Zhimai tablets.
