目的建立测定马钱子散中士的宁含量的HPLC方法。方法用高效液相色谱法,色谱柱为Dikma kromasil C18](250×4.6)mm,5μm,]检测波长为254nm。结果士的宁在进样量为0.05056~1.0112μg范围内呈良好线性关系(r=0.9999),平均回收率为99.26%,RSD为1.58%。结论该法简便准确。
Objective To establish a HPLC method for determining the content of sulfamate in Maqin San. The method was performed by high performance liquid chromatography with a column of Dikma kromasil C18 (250×4.6) mm, 5 μm, with a detection wavelength of 254 nm. The results showed that Shihsinging had a good linear relationship (0.059-1.0112μg) in the injection volume range (r=0.9999). The average recovery rate was 99.26% and the RSD was 1.58%. Conclusion This method is simple and accurate.
