摘要: 建立高效液相色谱-二极管阵列检测器-电雾式检测器(HPLC-DAD-CAD)法同时测定川佛手中香叶木苷、橙皮苷、5,7-二甲氧基香豆素、柠檬苦素和诺米林等5个成分含量的方法。研究结果表明,川佛手中香叶木苷、橙皮苷、5,7-二甲氧基香豆素、柠檬苦素和诺米林分别在106.6—533 ng(r=0.9998)、102.4—512 ng(r=0.9999)、103.0—515 ng(r=0.9999)、82.2—411 ng(r=0.9996)、127.6—638 ng(r=0.9994)范围内线性关系良好,平均加样回收率分别为105.04%、107.19%、98.39%、105.01%、94.33%,RSD值分别为1.96%、1.67%、2.72%、2.39%、0.45%。8批样品中橙皮苷、香叶木苷、5,7-二甲氧基香豆素、柠檬苦素和诺米林的百分含量分别为0.026%—0.168%、0.036%—0.081%、0.064%—0.256%、0.016%—0.084%、0.068%—0.116%。建立的HPLC-DAD-CAD测定5个成分含量的方法稳定可靠,重复性好,可为川佛手的质量控制方法研究提供参考。

Abstract: To establish a method for the simultaneous determination of diosmin, hesperidin, 5,7-dimethoxycoumarin, limonin and nomilin in Citri Sarcodactylis Fructus by high performance liquid chromatography coupled with diode array and charged aerosol detector (HPLC-DAD-CAD). Results: The concentrations of diosmin, hesperidin, 5,7-dimethoxycoumarin, limonin and normilin were 106.6—533 ng (r=0.9998), 102.4—512 ng (r=0.9999), 103.0—515 ng (r=0.9999) and 82.2—411 ng (r=0.9996), 127.6—638 ng (r=0.9994), respectively The average recoveries were 105.04%, 107.19%, 98.39%, 105.01% and 94.33%, respectively. The average recoveries were 105.04%, 107.19%, 98.39%, 105.01% and 94.33%, respectively. RSD values were 1.96%, 1.67%, 2.72%, 2.39% and 0.45%, respectively. The contents of hesperidin, diosmin, 5,7-dimethoxycoumarin, limonin and nomilin in 8 batches of samples were 0.026%—0.168%、0.036%—0.081%、0.064%—0.256%、0.016%—0.084% and 0.068%—0.116%, respectively. Conclusion: The established HPLC-DAD-CAD method is stable, reliable and reproducible, which can provide a reference for the study of quality control methods of Citri Sarcodactylis Fructus.-
