摘要
提供了一种准确测定口服液中神经酸含量的方法。样品经预处理后,用BF3-CH3OH酯化,以邻苯二甲酸二壬酯为内标测定口服液中神经酸含量。所提供的方法线性范围为0.3~3g/L,平均回收率为97.04%,RSD为0.90%,经空白试验,对神经酸含量测定无干扰。
A method for determination of nervonic acid in oral tonic has been developed by gas chromatography. The samples were derivatized by BF3--CH3OH. Dinonyl phthalate was used as the internal standard. The calibration curve was linear over a range from 0. 3 g/L to 3 g/L with a correlation coefficient of 0.999 4. The average recovery of the method was 97. 04% and the RSD was 0. 90%. The method has been successfully applied to quality control of nervonic acid in oral tonic.
