摘    要:目的:建立蒙药清热八味胶囊中肉桂酸的含量测定方法。方法:采用反相高效液相色谱(RPHPLC)法,色谱柱Diamosil C18柱(4.6mm×250mm,5μm),流动相:水-乙睛-甲醇-乙酸(61∶34∶5∶0.1);检测波长:为267nm,流速:1mL/min,进样量:10μL。结果:肉桂酸的线性范围0.030-0.240μg(r=0.9999),平均加样回收率(n=9)99.986%,RSD 1.49%。结论:本法准确、简便,重复性好,可作为蒙药清热八味胶囊的质量控制方法。

关 键 词:反相高效液相色谱法  肉桂酸  清热八味  含量测定

Abstract:Objective:To establish a RP-HPLC method for determining the content of Cinnamic acid in Qingrebawei. Methods:A chromatographic column of Diamosil C 18(4. 6 mm×250 mm,5μm) was used,the mobile phase was water-acetonitrile-methanol-Acetic Acid(61 : 34 : 5 : 0. 1). The flow velocity was 1mL/min,detection wave length was 267nm. Results:The linear range of Cinnamic acid was 0 . 030 - 0 . 240μg ( r = 0 . 9999 ) , average recovery ( n = 9 ) 99 . 986% ( RSD 1 . 49%) . Conclusion:The method was accurate and simple with a higher repeatability,which can be used for the quality control of Qingrebawei.
Keywords:RP-HPLC  cinnamicacid  qingrebawei  quantitative determination
