ABSTRACT
<p><b>OBJECTIVE</b>To develop a HPLC method for determining the content of protopine in Corydalis racemose.</p><p><b>METHOD</b>Analysis was performed on a Gemini C18 column (4.6 mm x 250 mm, 5 microm) eluted with acetonitrile-water containing 0.8% triethylamine and 3% acetic acid acetum (2080) as the mobile phase. The flow rate was 1.0 mL x min(-1). The detection wavelength was 289 nm.</p><p><b>RESULT</b>The average content of protopine in Herb of Racemose Corydalis was 0.905%. The calibration curve of protopine was linear between 0.124-1.36 microg (r = 0.9999). The average recovery was 98.49% with RSD 1.9%.</p><p><b>CONCLUSION</b>This method is simple, reproducible and can be used to determine the content of protopine in C. racemose.</p>
