摘要
目的：建立谷物中桔霉素含量的测定方法。方法：以60%乙醇作提取剂,C18吸附剂分散固相萃取净化样品中的桔霉素,应用高效液相色谱进行分析。结果：该方法标准曲线方程Y=3.13×10-7X-5.59×10-2,线性相关系数R2=0.9999,检出限为0.005mg/L,重复性实验精密度（RSD）为4.51%,加标回收率范围为87.7%-96.4%,所测的三种谷物样品桔霉素含量为0.116-0.385μg/g。结论：该方法简便、准确,可用于谷物中桔霉素含量的测定。
Objective.To establish a method to determine the content of citrinin in grain. Method： The samples were extracted with 60% ethanol,and cleaned up by dispersive solid-phase extraction with CL8 dispersant sorbent and ready for HPLC determination.Results-A standard curve equation was built as follows.Y = 3.13 × 10^-7X-5.59×10-^2 with linear correlation coefficient of 0.9999 and RSD was 4,51%.The average recovery range was 87.7%-96.4%.The citrinin content range of the samples was 0.116-0.385μg/g.Conclusion：This method was sample and accurate, which could be used for detecting citrinin in grain.
