摘 要:目的:建立同时测定痛安注射液中木兰花碱、原阿片碱、黄连碱、白屈菜碱含量的HPLC方法。方法:采刖GeminiC18色谱柱(4.6mm×250mm,5μm),流动相乙腈(A).0.02mol·L^-1磷酸二氢钾(B)梯度洗脱,流速1.0mL·min^-1,检测波长230nm(木兰花碱),290nm(原阿片碱、白屈菜碱),360nm(黄连碱),柱温30℃。结果:木兰花碱、原阿片碱、黄连碱、白屈菜碱分别在10.856~108.560(r=0.9998),24.712~247.120(r=0.9996),3.464~34.640(r=0.9996),39.296~392.960mg·L^-1(r=0.9999)线性关系良好,回收率在97.5%-101.8%。结论:建立的方法准确可靠,可以用于测定痛安注射液中木兰花碱、原阿片碱、黄连碱、白屈菜碱的含量。Objective: To establish an HPLC method for content determination of magnoflorine, protopine, coptisine and chelidonine in Tong'an injection. Method: Gemini C18 (4.6 mm ×250 mm, 5 ×m) was used with the mobile phase of aeetonitrile-0.02 mol ·L^-1 monopotassium phosphate at a flow rate of 1.0 mL ·min^-1 The detection wavelength was set at 230 nm for magnoflorine, 290 nm for protopine and chelidonine, 360 nm for coptisine, and the column temperature was maintained at 30 ℃. Result: Calibration curves of the magnoflorine, protopine, ehelidonine and coptisine in Tong'an injection showed good linear relationship: 10. 856- 108. 560 (r=0.999 8), 24. 712-247. 120 (r =0.999 6), 3. 464-34. 640 (r =0.999 6), 39. 296-392. 960 mg·L^-1 (r = 0. 999 9 ). The average recoveries of the components above were between 97.5%-101.8%. Conclusion: The method was feasible, accurate and stable, which could be used for determination of magnoflorine, protopine, coptisine and chelidonine in Tong'an injection.
