【摘要】:目的建立气相色谱法同时测定雌性柞蚕蛾中棕榈酸、棕榈油酸、硬脂酸、油酸、亚油酸、α-亚麻酸6种成分的含量。方法样品甲酯化后,采用Agilent VF-23 ms毛细管柱(30 m×0.25 mm,0.25μm),柱温程序升温,进样口:250℃,FID检测器:300℃,流速:0.6 m L·min~(-1),进样量:1μL。结果棕榈酸、棕榈油酸、硬脂酸、油酸、亚油酸、α-亚麻酸质量浓度分别在0.032~0.288、0.0064~0.058、0.0064~0.058、0.049~0.443、0.015~0.137、0.083~0.745 g·L~(-1)内呈良好的线性关系(r≥0.999 1),平均回收率为97.8%~99.6%(RSD≤1.7%,n=9)。结论该方法可用于控制雌性柞蚕蛾药材和饮片的质量。
