| 摘 要： | 目的:探讨金银花清除DPPH自由基的活性成分。方法:采用HPLC获得金银花甲醇提取液指纹图谱,并对色谱图进行融合处理;同时建立提取液对DPPH自由基的清除方程,采用双变量相关分析将DPPH自由基的半数清除率IC50与HPLC指纹图谱共有峰的标准化峰面积比值关联。结果:4(绿原酸),10(异绿绿原酸B),12(异绿原酸C)号共有峰含量变化与DPPH自由基清除活性显著负性相关(P0.05)。结论:金银花液相指纹图谱与清除DPPH自由基的谱效关系,对于金银花药用物质基础研究具有一定参考价值。

| Abstract: | Objective: To investigate the active components in Lonicerae Japonicae Flos for scavenging DPPH free radicals. Method: The HPLC fingerprints were developed and merged. Meanwhile, the DPPH radical scavenging equation was established. The bivariate correlation analysis was applied to correlate the scavenging DPPH Free radical parameter IC50 and the standardized peak area ratio of common peaks of HPLC fingerprints. Result: The changes in the contents of common peaks 4 (chlorogenic acid), 10 (isochlorogenic acid B) and 12 (isochlorogenic acid C) show significant negative correlation with DPPH free radical scavenging activity. Conclusion: The chromatography-efficacy relation between the HPLC fingerprints and the DPPH free radical scavenging activity provides a certain reference value for the basic study on medicinal material base of Lonicerae Japonicae Flos. |
