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( RP -HPLC) 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。

[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,5 μm)
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.
