Olive tree is one of the most important plants related to the economical interest in Albania. Eventually it is one of the study objects, which constitutes a cultivation area of more than 40 000 ha. Studies with focus the olive tree mainly have been of statistical profile comprising, (yield, area of plantation and their exploitation) and botanical (morphological determinations of olive cultivars). Recently has been growing interest on the analytical studies of chemical compositions. One of the main olive autochthonous cultivars used as a Table olive is the Kokermadh Berati cultivated in the region with same name. It contributes by 20% of the total fund of the ~6 million olive trees. This study has analyzed samples from the crop year 2010-2011. It evaluated the oil content, fatty acid profiles, total phenol content and antioxidant activity. GC analysis of fatty acids revealed that the oleic acid content resulted in 76.26%. The content of palmitic acid is relatively low, 10.41%). The level of linoleic acid is considered relatively low (6.92%). The content of the stearic acid resulted 2.20%, while the linolenic acid resulted 0.67%. The Saturated Fatty Acids (SFA) group resulted in 12.92%, the Monounsaturated Unsaturated Fatty Acid (MUFA) content to 79.53% and the Poly Unsaturated Fatty Acid (PUFA) 7.59%. The nutritional value of n-6/n-3 show very interesting values by 10.31. The Total Phenol Content (TPC) expressed as Gallic Acid Equivalency (GAE) resulted 226.97 ±1.40 mg GAE/kg Olive Oil.
