Determination of salidroside in Liquor Ligustrum Lucidum formula granules by HPLC
OBJECTIVE To establish an HPLC method for determining the content of salidroside in the formula granules of Ligustrum lucidum.METHODS Using C18 Chromatographic column,using methanol-water(15∶85)as the mobile phase,gradient elution was performed,the flow rate of 1.0mL·min-1,the detection wavelength of 275nm.RESULTS Salidroside showed a good linear relationship in the range of 0.5~5.0 mg·mL-1 with a recovery rate of 99.94%and RSD of 1.43%(n=6).CONCLUSION This method is easy to operate,has good reproducibility and high stability,and can be used for the quality control of Liquor Liqustrum Lucidum formula granules.
