摘要: 本文对葫芦脲(CB)作为一种新型固相微萃取(SPME)涂层材料进行了研究并用于中药白豆蔻的气相色谱分析测定.本文采用的CB SPME涂层制备方法简便、快速,并具有良好的热稳定性和重复性.CB[6]SPME萃取得到的主要成分与水蒸气蒸馏(SD)法基本一致,并且CB[6]SPME对色谱后流出的目标成分的相对峰面积比明显高于SD法和商品SPME萃取材料PDMS/CAR和PDMS/DVB,这可能是由于葫芦脲的特殊分子结构及其与组分分子间选择性作用所致.葫芦脲作为一种新型SPME涂层材料具有很大的研究潜力和应用前景.

Abstract: Cucurbiturils (CB) were investigated as a new coating materials for solid phase microextraction (SPME) and were used for the extraction of the volatile components in round cardamon seed followed by gas chromatography. The preparation method for CB[6] SPME is simple, rapid and provides thermally stable layer with good repeatability for multiple extraction. To evaluate the extraction capability of CB[6] SPME, steam distillation and commercial SPME fibers of PDMS/ CAR and PDMS/DVB were also used for comparison. The results show that CB[6] SPME can extract similar components to SD and the commercial fibers, but achieve higher relative peak area percent for the late-eluted components, which is probably originates from the specific molecular structure and interactions of cucurbiturils with analytes of interest. The present work demonstrates the great potential of cucurbiturils as a new type of SPME coating materials.
