| 摘 要： | 目的:建立气相色谱法测定薄荷传统饮片及薄荷新型饮片中薄荷脑的含量。方法:色谱柱:HP Inno-wax(30 m×0.320 mm×0.5μm);进样口温度:250℃;FID检测器温度:250℃;初始温度120℃,保持2 min后以5℃/min的速率升温至150℃,保持6 min;以15℃/min的速率升温至220℃,保持6.667 min。分流比:20∶1;载气:N2;体积流量:1.0 mL/min。结果:薄荷脑在0.034～1.36 g.L-1的范围内呈良好线性关系(r=0.9998),加样回收率为99.68%,RSD为3.23%(n=6)。结论:本测定方法快捷,灵敏,准确,重现性好,可用作薄荷新型饮片和薄荷传统饮片的质量控制。
