Objective To establish a method for the simultaneous determination of protopine, palmatinechloride, dehydrocorydaline, tetrahydropalmatine, and corydaline in Corydalis Rhizoma by UPLC-MS/MS. Methods Waters HSS T3 C₁₈ column (100 mm×2.1 mm, 1.7 μm) was used with mobile phase consisted of acetonitrile-0.1% ammonium acetate by gradient elution. The column temperature was 40℃ and the volume of injection was 5 μL with flow rate of 0.3 mL/min. Multiple-reaction monitoring scanning was used for quantification with electrospray positive ions model. The ion source temperature was 150℃, the capillary voltage was 3.0 kV, the cone voltage was 50 V, the desolvation gas flow rate was 800 L/h, and the desolvation gas temperature was 400℃. Results The linear ranges of protopine, palmatinechloride, dehydrocorydaline, tetrahydropalmatine, and corydaline were 0.20-10.12 ng, 0.25-12.58 ng, 1.02-51.20 ng, 0.85-42.64 ng, and 0.39-19.44 ng, respectively. The average recoveries were 97.48%, 100.16%, 101.61%, 96.05%, and 104.17% with RSD of 1.70%, 2.05%, 2.55%, 0.74%, and 3.24%, respectively. The contents of five alkaloids in Corydalis yanhusuo from different origins were obviously different. The contents of five alkaloids in Corydalis Rhizoma from Zhejiang Province origin were higher than those of other origins, and the content of dehydrocordine was the highest among the five alkaloids. Conclusion The established method is easy, rapid, and accurate which can be used for the content determination of five alkaloids in Corydalis Rhizoma
