摘要
目的:建立高效液相色谱法测定清热解毒片中绿原酸的含量方法。方法实验条件为色谱柱:Kromasil C18(250mm×4.6mm,5μm),流动相:乙腈-0.4%的磷酸(20:80)检测波长:324nm,流速为1.0ml·min-1。结果:绿原酸平均回收率为98.89%,RSD为0.68%(n=6)。结论:该法简便,结果准确,专属性强,重现性好,可将其作为清热解毒片的质控指标之一。
Objective To establish high performance liquid chromatography to detect the contents of qingrejiedu films chlorogenic acid .Methods:the experimental conditions for chromatographic column KromasilCL, (250mm ×4.6mm, 5 μm ) ,mobile phase: acetonitrile-0.4%phosphate(20:80),Detected wavelength: 324nm,tending now velocity of 1.0ml ·min-1. Results: the average recovery for pingyi 98.89% ,RSD 0.68% (n=6)o Conclusion The method is simple,accurate and strong speciflcity, reproducible and can be as qingrejiedu films slice quality indexes.
