两种固相萃取柱在乙酰氨基阿维菌素药动学前处理中的比较

         

摘要

为评价乙酰氨基阿维菌素(EPR)药动学前处理中两种固相萃取(SPE)柱的净化、萃取效果,首先在空白胎牛血清中加入一定量的EPR标准溶液,经色谱甲醇提取后,分别经Agilent和Waters公司的C18SPE柱对其进行萃取,再经N-甲基咪唑和三氟乙酸酐衍生化,最后用超高效液相色谱-荧光检测器进行测定;同时,将等量的EPR标准溶液进行衍生化,用超高效液相色谱-荧光检测器进行测定,将其结果作为对照;以绝对回收率作为评价两种SPE柱净化、萃取EPR效果的标准.结果显示,含有EPR的胎牛血清分别经Agilent和Waters公司的C18SPE柱萃取后,两者的EPR峰形均尖锐对称且无明显杂质峰,但绝对回收率有差异,分别为94.50%和85.79%.结果表明,Agilent公司的C18SPE柱对EPR的萃取效果更理想.%In order to evaluate the purification and extraction effects of different brands of SPE columns in pretreatment of pharmacokinetics experiments of Eprinomectin(EPR). Firstly,a certain amount of EPR standard solution was added to blank fetal bovine serum. Methanol was used to purify EPR in serum. Then the solution was extracted by Agilent's and Waters' C18SPE columns respectively,and was derivatized with N-methylimidazole and trifluoroacetic anhydride. The final products were determined by ultra performance liquid chromatography-fluorescence detector. At the same time,an equal amount of EPR standard solution was derivatized and determined by ultra performance liquid chromatography-fluorescence detector,and the result was taken as the control group. Besides,the absolute recovery rate was the criteria for evaluating the two brands of SPE columns. The results showed that,after being extracted by Agilent's and Waters'C18SPE columns respectively,the two EPR peaks were sharp symmetry without obvious impurity peaks,but there was a difference in absolute recovery rates,which were 94.50% and 85.79%,respectively. As a conclusion,the C18SPE column of Agilent company was more effective for EPR extraction.
