ABSTRACT
Objective:
To establish a method for determining the content of imperatorin,phillyrin and forsythoside A in Kanggan Jiedu granules by UPLC.Methods:
An Agilent Eclipse Plus C18 column(100 mm × 2. 1 mm,1. 8 μm)was used,the mobile phase was acetonitrile-0. 2% acetic acid with gradient elution,the flow rate was 0. 2 ml· min-1 and the column temperature was 30℃. The de-tection wavelength was set at 335 nm in the first 8 min for forsythoside A, and then changed to 277 nm for phillyrin between 8 and 10 min followed by 300 nm for imperatorin between 10 and 15 min.Results:
The linear range of imperatorin was 0. 374-3. 366 μg·ml-1 (r=0. 999 6)and the average recovery was 99. 12%(RSD=1. 07%),that of phillyrin was 0. 568-5. 112 μg·ml-1(r=0. 999 4)and the average recovery was 100. 39%(RSD=0.93%,n=9),and that of forsythoside A was 0.738-6.642μg·ml-1(r=0.999 7)and the average recovery was 99. 78%(RSD=1. 14%,n=9).Conclusion:
The method is rapid,simple,accurate and specific,which can be used for the determination of imperatorin,phillyrin and forsythoside A in Kanggan Jiedu granules.
