摘要
采用固相微萃取(SPME)纤维包覆碳/聚二甲基硅氧烷(CAR/PDMS)或二乙烯苯/碳/聚二甲基硅氧烷(DVB/CAR/PDMS)，提取脂肪组织(肾周、尾部、肺脏)顶空挥发性化合物(VCs)。与DVB/CAR/PDMS涂层提取相比，CAR/PDMS涂层提取在肾周脂肪(53 vs 41)、尾脂肪(51 vs 47)和胆管脂肪(35 vs 33)中获得了更多的vc。醛类保留指数的增加增加了在DVB/CAR/PDMS上的吸附。这种纤维还提供了良好的羧酸产率。如果目标是识别醛类，特别是脂肪酸氧化产物和低分子量碳氢化合物，以及大量的vc，那么CAR/PDMS纤维可以推荐用于脂肪组织中的vc。然而，在针对羧酸、酯和高分子量醛的情况下，由于DVB/CAR/PDMS对上述化合物的高亲和力，因此可以使用DVB/CAR/PDMS。进一步研究最佳提取时间，确定vc达到平衡的时间。
COMPARISON OF DIFFERENT SOLID PHASE MICROEXTRACTION FIBERS IN EXTRACTION OF VOLATILE COMPOUNDS FROM ADIPOSE TISSUE
The volatile compounds (VCs) in headspace of adipose tissues (perirenal, tail, caul) were extracted by solid-phase microextraction (SPME) fiber coated with carboxen/ polydimethylsiloxane (CAR/PDMS) or divinylbenzene/ carboxen/ polydimethylsloxane (DVB/CAR/PDMS). In extraction with CAR/PDMS coating compared to DVB/CAR/PDMS, more VCs were obtained in perirenal (53 versus 41), tail (51 vs 47) and caul (35 vs 33) fats. Increased retention index for aldehydes increased the adsorption on DVB/CAR/PDMS. This fiber also provided a good yield for carboxylic acids. CAR/PDMS fiber could be recommended for VCs from adipose tissues if the goal is to identify aldehydes, especially fatty acid oxidation products and low molecular weight hydrocarbons, as well as greater number of VCs. However, in case of targeting carboxylic acids, esters, and also high molecular weight aldehydes, DVB/CAR/PDMS could be utilized due to its high affinity for mentioned compounds. Furthermore, the optimum extraction time should be studied to determine the time for VCs to reach equilibrium.
