| Abstract: | Objective:To establish a HPLC method for the determination of peoniflorin and osthole in Chonghe Ointment.Methods:The HPLC analysis was performed on a Phenomisl C18 column(150 mm×4.6 mm,5 μm) with acetonitrile-water as mobile phase in gradient elution;the flow rate was 1.0 mL·min-1.The column temperature was 35 ℃.The detection wavelengths were set at 230 and 330 nm.Results:The linear ranges of peaoniflorin and osthole were 3.12～249.8 μg·mL-1(r=0.999 8)and 1.54～123 μg·mL-1(r=0.999 9).The average recoveries were 101.0%(RSD=1.07%,n=9)and 100.8%(RSD=1.21%,n=9),respectively.Conclusion:The method is convenient,rapid and accurate.It can be used in the quality control of Chonghe Ointment. |
