Sažetak
The Edible dormouse is Croatian autochthonous game. Hunted dormice can be used in nutrition and dormice oil is traditionally used in wound treatment in some regions of Croatia. So, the objective of this study was to determine the fatty acid (FA) composition of the liver, kidney and subcutaneous adipose tissue (SAT) in Edible dormouse (Glis glis) and the influence of gender. This study was conducted on 17 Edible dormice (10 females and 7 males). Samples of SAT, the liver and the kidneys were collected during the legal hunting season (September– October 2017). The samples of tissues were homogenised, total lipids extracted by using the Folch et al. (1957) method and FA composition was determined by gas chromatography. The most prevalent FA in the kidneys and SAT of Edible dormice were monounsaturated FA (MUFA). The most prevalent MUFA in both tissues was C18:1cis-9 (53.17 ± 10.53 ; 40.98 ± 9.01, respectively). The second abundant FA were saturated FA (SFA), with C16:0 (22.29 ± 6.52 ; 19.72 ± 7.94, respectively) as the most prevalent FA. The least represented were polyunsaturated FA (PUFA), of which the linoleic acid (C18:2n- 6) had the highest concentration. The highest number of FA was detected in the liver, and the liver tissue had the highest percentage of PUFA and SFA among the examined tissues. The ratio of n6/n3 in the liver of Edible dormice was 0.85/1.35. The highest percentage of MUFA was detected in SAT. A significantly higher percentage of C18:3n-3 and ratio of n6/n3 was found in the liver and SAT in the male than in the female dormice (p < 0.05). We did not find a significant difference in the kidney fatty acid profile between the male and female dormice. In the kidneys, the percentage of the arachidonic acid (AA) was 2.5 times higher than in the liver and SAT. The fatty acid composition in all three tissues is very similar between males and females, and the n6/n3 ratio is optimal in the liver. The higher percentage of AA in the kidneys could be due to prostaglandins synthesised from AA that influence filtration and reabsorption in the kidneys.
