Abstract
建立同时测定好胃来软胶囊中木香烃内酯和去氢木香内酯含量的方法。方法:采用高效液相色谱法。色谱柱为Dikma C18,流动相为乙腈-水(V/V,55∶45),流速为1.0 ml/min,检测波长为225 nm,柱温为25℃,进样量为10μl。结果:木香烃内酯、去氢木香内酯检测质量浓度线性范围分别为24.00~108.00μg/ml(r=0.9997)、20.88~93.98μg/ml(r=0.9998);精密度、稳定性、重复性试验的RSD<1%;加样回收率分别为98.71%~100.00%(RSD=0.25%,n=6)、96.88%~99.18%(RSD=0.40%,n=6)。结论:该方法操作简便、稳定性和重复性好,可用于好胃来软胶囊中木香烃内酯和去氢木香内酯含量的同时测定。
