摘  要：
目的:建立芝麻油样品中芝麻酚含量的超高效液相色谱(UPLC)测定方法。方法:样品经90%乙腈水提取后,用水定容,进行UPLC定量分析。实验采用BEH C18色谱柱,以水和乙腈为流动相。结果:方法测定低限为5.0mg/kg,在5.0～500.0mg/kg添加水平范围内,芝麻酚回收率为81.5%～90.9%,相对标准偏差为1.8%～3.5%。结论:方法准确度和稳定性较好,操作简单快捷,样品净化效果好,测定低限能够满足限量要求。

摘  要：
Objective:A UPLC method for the determination of sesamol in sesame oil had been developed.Methods:Sesamol was extracted from sample with 90% acetonitrile-water,and dilute with water to volume. The analyte was determinated by UPLC for the quantitative determination,and quantified by the external standard curve. The separation was performed on a UPLC BEH C18column with a system of water-acetonitrile as mobile phase. Results:The limit of determination of this method was 5.0mg/kg. The detection limit of 5.0~500.0mg/kg proved to be much better than the previously reported one. Average recoveries of sesamol ranged from 81.5% to 90.9% ,with relative standard deviations between 1.8% ～3.5% . Conclusion:The result demonstrated that the method was simple,accurate and suitable for the identification and quantification of sesamol in sesame oil.
