本文选题:高效液相色谱法 + 干髓糊剂 ; 参考:《中国药房》2017年30期
【摘要】:目的:建立同时测定干髓糊剂中丁香酚和麝香草酚含量的方法。方法:采用高效液相色谱法。色谱柱为Wonda Cract C_(18),流动相为甲醇-0.2%磷酸溶液(梯度洗脱),流速为1.0 mL/min,检测波长为274 nm,柱温为25℃,进样量为10μL。结果:丁香酚和麝香草酚检测质量浓度线性范围分别为0.02~0.19 mg/mL(r=0.999 7)、0.03~0.30 mg/mL(r=0.999 6);精密度、稳定性、重复性试验的RSD2.0%;加样回收率分别为95.85%~99.84%(RSD=1.11%,n=9)、95.81%~100.91%(RSD=1.59%,n=9)。结论:该方法操作简便、结果准确,可用于干髓糊剂中丁香酚和麝香草酚含量的同时测定。
