Objective:To develop an HPLC method for the determination of the content of Stachydrine in QLTJN.Methods:A Hypersil SCX C18 column was used as the chromatographic column.The mobile phase consisted of Potassium phosphate monobasic(0.025 mol/L
pH2.0)-Triethylamine(100∶0.25)
the flow rate was 1.0 mL/min.The UV detection wavelength was 192nm.Results:There was a good linear relationship between the concentration of Stachydrine and peak area value when the concentrations of Stachydrine was within the range of 2.8~6.5 μg(r=0.9998).The average recovery was 98^6%
RSD=0.77%(n=5).Conclusion:The method was accurate
sensitive
reproducible and may be used in the determination of Stachydrine in QLTJN.
