Objective: To establish a HPLC method for the determination of shanzhiside methylester in the preparations of Lamiophlomis rotata . Method: HPLC analysis was performed on Symmetry C18 (5 μm) column and gradient elution ∶91)
9-20 min
acetonitrile-water (15 ∶85)] was used as the mobile phase at a flow rate of 1.0 ml ·min-1. The column temperature was 20 ℃ and the detection wavelength was at 235 nm. Result: The linear range of shanzhiside methylester was 9.6~115.2 μg ·mL-1 (r=0.999 8) and the average recovery was 97.69%. Shanzhiside methylester could be detected from all preparations and the content variedgreatly. Conclusion: The method can be applied to determine the content of shanzhiside methylester in the preparations of L. rotata .
