【摘要】:目的:建立毛细管气相色谱法(CGC法)检测榄香烯原料药的有关物质。方法:采用DB-WAXetr(60 m×0.32 mm×0.25μm)毛细管气相色谱柱,柱温为程序升温(起始柱温为80℃,维持5 min,以3℃·min~(-1)的速率升温至185℃,再以20℃·min~(-1)的速率升温至230℃,维持60 min),进样口温度230℃,检测器温度230℃,分流比为10:1,进样量1.0μL。结果:方法的专属性强,β-榄香烯质量浓度在5.003 6~160.12μg·mL~(-1)的范围内呈线性(r=1.000 0,n=7),最低检出限为0.87μg·mL~(-1);3批样品的有关物质总量依次为15.4%、15.5%、14.7%。结论:本方法可用于榄香烯原料药的有关物质检测。
