Variations de la composition en acides gras polyinsaturés (w3) chez Diplodus annularis des côtes tunisiennes
Written by sctunisie no commentsHealth virtues of Mediterranean diet are particularly due to fish consumption. The beneficial effect of sparidae among other fish species with high polyunsaturated fatty acid levels is in cardiovascular and tumoral disease preventions. In our study we followed the polyunsaturated fatty acid level variations in an immature sparida species Diplodus annularis collected from three regions of Tunisian coasts north (Golf of Tunis), East (Monastic) and the south (Djerba - Zarzis). The results obtained by gas chromatograph with capillary column show the following composition of total fatty acids in the north 2.94, in the center and in the south 1.42 nigig dry matter. The statistical analysis reveals a significant difference in favour of the north value compared to those of the center and the south (P < 0,05). Moreover, our results indicate a higher level of polyunsaturated fatty acids (w3) in favour of the northern region.
