Özet
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.
