The effects of cultivation area and altitude variation on the composition of fatty acids of Laurus nobilis L. berries in Nothern Turkey and Abkhazia

Abstract

The aim of the study was to determine and compare the fatty acids contents of Laurel berries (Laurus nobilis L.) grown in Trabzon, Bartın, Samsun and Abkhazia. Fleshy parts of laurel berries and seeds were analyzed separately to reveal yields of fixed oils. Three altitude ranges were determined for the study and samples were collected from the ranges that can be found from these elevations. These were (0-100m, 100-300m and 300-600m). Fleshy parts of laurel berries and seeds were analyzed separately to reveal yields of fixed oils. Automatic extraction technique was used for getting fixed oil and GC-FID device was used for characterization and comparison of berry oil. The results showed that the fixed oil yield of fleshy parts of berries ranged between 28.37% and 42.08%. The highest amount of fixed oil yield in fleshy part was obtained in Bartın (0-100 m). The fixed oil in of seeds ranged between 16.26% and 22.81%. The highest amount of fixed oil yield in seeds was obtained in Bartın (100-300 m). According to GC-FID results, oleic acid (27.06 % - 48.93%) was the most abundant fatty acid, lauric acid (0.49% -1.35 %) was the least abundant fatty acid in the fleshy parts of bay fruits. In seeds, lauric acid was the most common fatty acid (32.37%-44.49%) and arachidic acid (0.87%-1.17%) was the least fatty acid. According to results, it is thus deduced that, the amount and content of fixed is affected by cultivation area, altitude variation and the parts of laurel berry
