Objective: To establish a rapid HPLC-DAD method for the simultaneous determination of four compounds
namely picroside Ⅰ
Ⅱ
paeoniflorin and albiflorin std in Qinggan Shuyu granule. Method: The analytes were extracted by ultrasonic. The separation of the compounds was performed on Diamonsil (2)-C18 (4.6 mm×250 mm
5μm)column with acetonitrile-0.05%formic acid solution as mobile phase at the wavelength of 264 nm (picroside Ⅰ
Ⅱ) and 230 nm (paeoniflorin
albiflorinstd). Result: The four analytes demonstrated a good linearity (r>0.9991) within a relatively wide concentration range (0.0672-6.72μg for picroside Ⅰ
0.0174-17.4μg for picroside Ⅱ
0.01-10.00μg for paeoniflorin and 0.06-6.00μg for albiflorin std)
and the recoveries ranged between 97.90%-100.95%
with RSD of 1.7%
2.4%
1.4%
1.7%
respectively. Conclusion: The method was found to be accurate
simple and sensitive for the quantitative analysis on the four compounds in Qinggan Shuyu granule.
