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. |
