-----摘要:-------------------------------------------------------------------------------------------

目的: 建立RP-HPLC法同时测定紫苏子中α-亚麻酸和亚油酸的含量。 方法: 色谱柱为Agilent Eclipse XDB-C18(150 mm×4.6 mm,5 μm)色谱柱,流动相为乙腈-水(90∶10),流速1 mL·min-1,柱温30 ℃,检测波长205 nm。 结果: α-亚麻酸、亚油酸浓度分别在14.45~144.5 μg·mL-1(r=0.9998)和5.75~57.5 μg·mL-1(r=0.9999)范围内与峰面积呈良好的线性关系,平均回收率(n=6)分别为100.2%(RSD=2.3%)和101.2%(RSD=1.5%)。 结论: 本法简便、快速、准确,适用于紫苏子及紫苏子油中α-亚麻酸和亚油酸的同时测定。

Objective: To establish an RP-HPLC method for simultaneous determination of α-linolenic acid and linoleic acid in Fructus Perillae. Methods: The separation was carried out on an Agilent Eclipse XDB-C18(150 mm×4.6 mm,5 μm) column with a mixture of acetonitrile-water (90∶10) as the mobile phase at the flow rate of 1.0 mL·min-1;The column temperature was maintained at 30 ℃ and the detective wavelength was set at 205 nm. Results: The calibration curves of α-linolenic acid and linoleic acid were linear in the ranges of 14.45-144.5 μg·mL-1(r=0.9998) and 5.75-57.5 μg·mL-1(r=0.9999),respectively.The average recoveries(n=6) were 100.2%(RSD=2.3%) and 101.2%(RSD=1.5%). Conclusion: The method is simple,rapid and accurate,which is suitable for simultaneous determination of α-linolenic acid and linoleic acid in Fructus Perillae and Perilla oil.
