摘要
目的:建立GC法测定强力枇杷露中薄荷脑的含量测定方法。方法:采用Rtx-WAX毛细管柱(长30m、直径0.25mm、膜厚0.25μm),载气为氮气,FID检测器,柱温为恒温140℃,内标法测定薄荷脑含量。结果:薄荷脑在0.09996～0.99960mg·mL-1范围内浓度与峰面积呈良好的线性关系(r=0.9991,n=6),平均加样回收率为96.90%,RSD为1.22%(n=6)。结论:本方法快速、灵敏、结果准确,适用于强力枇杷露中薄荷脑的含量测定。
Objective：To establish a GC method for the Determaination of Menthol in Qianlipipalu. Methods：The Rtx - WAX capillary column （30m×0.25mm,0.25μm） was used with FID,nitrogen as the carrier gas,column temperature at 140%,the internal standard method was used to determine the content of menthol.Results： The menthol sample showed a good linear relationship at the range of 0.09996-0.99960mg·mL-1 （r=-0.9991,n=6）.The average recovery rate was 96.90% and RSD was 1.22%. Conclusions： This method is simple and accurate and able to determination of Menthol in Qianlipipalu.
