Abstract: Objective: To establish a TLC method and a HPLC method for the determination of scopolamine lactone content of Herba Patriniae, provide a basis for the quality research of Herba Patriniae. Methods: Using TLC as the identification method. Using HPLC as the content determination method, the chromatographic column: Ultimate Plus C18 (4.6 mm×250 mm,5 μm). Mobile phase: acetonitrile-0.5% glacial acetic acid (15∶85). Column temperature is 25 ℃. Flow rate is 1 mL·min-1. The detection wavelength is 343 nm. Results: Fluorescent spots with the same color as the reference medicinal material were detected in TLC identification; Scopolamine lactone has a good linear relationship in the range of 0.838 4-2.96 μg·mL-1 (functional relationship: Y=39.233X+7.021 5, r=0.999 9), the recovery rate is 91.0%-97.9%, the average value is 95.4%, and the RSD (n=6) is 3%. Conclusion: the identification method has good specificity, the content determination method is specificity, stability, reproducibility and accuracy, which can be used for the quality control of Herba Patriniae.
