摘 要:目的:建立马钱子散中士的宁含量的高效液相色谱测定方法。方法:采用Diamonsil-C18柱(250mm×4.6mm,5μm),以甲醇-含0.1%甲酸和0.1%二乙胺的水溶液为流动相,流速为1.0mL·min-1,检测波长为254nm。结果:士的宁进样量在0.0073~0.0584mg·mL-1浓度呈良好的线性关系(r=0.9996),平均回收率为97.94%,RSD=1.0%(n=6)。结论:该方法简便、准确、快速,适用于马钱子散中士的宁的含量测定。:Objective:To develop a reversed phase HPLC method for determining the content of strychnine in Nux Vom- lea powder. Methods:The HPLC separation was performed on a Diamonsil Cl8 column (250 mm x4. 6 ram,5 Ixm). The mo- bile phase was a mixture of methanol and water containing 0. 1% formic aeid and 0. 1% diethylamine and delivered at a flow rate of 1.0 mg · mL-1. The detection was done at 254 nm. Results:The ealibration curve was found to be linear in the con eentration range of 0. 0073 ~ 0. 0584 mg · mL-l ( r = 0. 9996 ). The mean reeovery of stryehnine was 97.94 % ( RSD = 1.0 %, n = 6 ). Conclusion: the developed HPLC method was simple, accurate and rapid, and suitable for monitoring of strychnine in Nux Vomiea powder.
