Title: Determination of Polydatin in Chushi Zhiyang Ointment by HPLC
Abstract: Objective:To establish a method for determination of polydatin in Chunshi Zhiyang ointment.Methods:Samples were analyzed on an Agilent TC-C18 column(250 mm×4.6 mm,5 μm)using acetonitrile-water(23:77)as mobile phase.Speed of flow was 1.0mL·min-1 and examination wave length was 306 nm.Results:Polydatin showed a good linearity in the range of 0.0384~0.192 μg,regression equation was S=0.0005m+0.0009(r=0.9999)and the average recovery was 100.02%(RSD=1.96%,n=6).Conclusion:The established methods are simple,accurate,reliable and can be used for the quality control of ointment.
