Abstract :The volatile compounds insert ignore into journalissuearticles values(VCs); in headspace of adipose tissues insert ignore into journalissuearticles values(perirenal, tail, caul); were extracted by solid-phase microextraction insert ignore into journalissuearticles values(SPME); fiber coated with carboxen/ polydimethylsiloxane insert ignore into journalissuearticles values(CAR/PDMS); or divinylbenzene/ carboxen/ polydimethylsloxane insert ignore into journalissuearticles values(DVB/CAR/PDMS);. In extraction with CAR/PDMS coating compared to DVB/CAR/PDMS, more VCs were obtained in perirenal insert ignore into journalissuearticles values(53 versus 41);, tail insert ignore into journalissuearticles values(51 vs 47); and caul insert ignore into journalissuearticles values(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.
