| 中文摘要: |
| 建立了快速、灵敏测定微生物油脂中花生四烯酸(AA)含量的气相色谱法(GC).采用HP-INNOWAX毛细管柱,氢火焰离子化检测器(FID),优化了分析花生四烯酸酯化产物的色谱条件.结果表明:花生四烯酸甲酯(AA - ME)在0～1.00 mg/mL范围内具有较好线性,相关系数为0.999 6,检测限为0.000 5 mg/mL,相对标准偏差(RSD)为1.49％,回收率在95.86％～105.32％；花生四烯酸乙酯( AA - EE)在0～1.23 mg/mL范围内线性良好,相关系数为0.999 9,检测限为0.003 0 mg/mL,RSD为0.60％,回收率在97.79％～103.61％. |
