【摘要】:目的建立HPLC法同时测定痹通药酒中4种生物碱的含有量。方法该药物乙醚提取液分析采用Agilent C18色谱柱(5μm,4.6 mm×250 mm);流动相[乙腈-四氢呋喃(25∶15)]-0.1 mol/L醋酸铵,梯度洗脱;体积流量1.0 m L/min;柱温30℃;检测波长235 nm。结果新乌头碱、次乌头碱、乌头碱、苯甲酰新乌头原碱分别在39.87~199.36、99.63~498.13、13.87~69.33、39.65~198.27μg/m L范围内线性关系良好(r0.999 0),平均加样回收率分别为98.24%(RSD=0.75%)、99.54%(RSD=0.50%)、97.60%(RSD=1.54%)、99.52%(RSD=1.32%)。结论该方法简便、准确、可靠,可用于痹通药酒的质量评价和控制。
[Abstract]:Objective to establish a HPLC method for simultaneous determination of four alkaloids in Bitong medicinal wine. Methods the Agilent C18 column (4.6 mm 脳 250 mm);) was used for the analysis of the ether extract. The mobile phase [acetonitrile-tetrahydrofuran (25:15)] -0.1 mol / L ammonium acetate was used for gradient elution, the volume flow rate was 1.0 mL / min, the column temperature was 30 鈩,
