摘要:目的 建立高效液相色谱法(HPLC)同时测定复方藤乌软膏中6种乌头类生物碱含量的方法。方法 色谱柱为Agilent XDB-C18柱(250 mm×4.6 mm,5 μm);流動相A为乙腈-四氢呋喃(25∶8),B为0.1 mol/L醋酸铵溶液(每1000 mL加冰醋酸0.5 mL),梯度洗脱;流速:1 mL/min;检测波长:235 nm;柱温:25 ℃。结果 乌头碱在0.072~0.648 μg具有良好的线性关系(r=0.999 5),平均回收率为99.29%,RSD=1.25%;新乌头碱在0.062~0.648 μg具有良好的线性关系(r=0.999 5),平均回收率为99.12%,RSD=0.85%;次乌头碱在0.064~0.384 μg具有良好的线性关系(r=0.999 8),平均回收率为99.57%,RSD=1.07%;苯甲酰乌头原碱在0.056~0.672 μg具有良好的线性关系(r=0.999 2),平均回收率为98.11%,RSD=0.61%;苯甲酰新乌头原碱在0.055~0.993 μg具有良好的线性关系(r=0.999 9),平均回收率为99.27%,RSD=1.10%;苯甲酰次乌头原碱在0.078~0.702 μg具有良好的线性关系(r=0.999 8),平均回收率为99.08%,RSD=1.38%。结论 本方法操作简便、灵敏度高、重复性好,结果准确,可作为复方藤乌软膏中乌头类生物碱的含量测定方法。

Abstract:Objective To establish an HPLC method for the simultaneous determination of the 6 aconitum alkaloids in compound Tengwu Ointment. Methods Chromatographic column was Aglient XDB-C18 column (4.6 mm × 250 mm, 5 μm), with the mobile phase A of acetonitrile- tetrahydrofuran (25∶8), phase B was 0.1 mol/L ammonium acetate solution (0.5 mL acetic acid added to the 1000 mL) with gradient elution;the flow rate was 1 mL/min;the detection wavelength was set at 235 nm;the column temperature was 25 ℃. Results Aconitine was in the good linear range of 0.072-0.648 μg (r=0.999 5), with the average recovery of 99.29%, RSD=1.25%. Mesaconitine was in the good linear range of 0.062-0.648 μg (r=0.999 5), with the average recovery of 99.12%, RSD=0.85%. Hypaconitine was in the good linear range of 0.064-0.384 μg (r=0.999 8), with the average recovery of 99.57%, RSD=1.07%. Benzoylaconine was in the good linear range of 0.056-0.672 μg (r=0.999 2), with the average recovery of 98.11%, RSD=0.61%. Benzoylmesaconine was in the good linear range of 0.055-0.993 μg (r=0.999 9), with the average recovery of 99.27%, RSD=1.10%. Benzoylhypaconine was in the good linear range of 0.078-0.702 μg (r=0.999 8), with the average recovery of 99.08%, RSD=1.38%. Conclusion This method is simple, sensitive, repeatable and accurate, which can be used for determination of aconitum alkaloids in compound Tengwu Ointment.
