Determination of Fatty Acid Profiles in Seed, Fruit and Fruit Peel Parts of the Laurel (Laurus Nobilis L.) by GC-FID
Öz
The fixed oil of Laurus nobilis fruit is used as a fragrance, spice, and tea in the field of food today; and it is used in medicine with its various effects such as antifungal, antioxidant and antimicrobial. While obtaining Laurus nobilis fixed oil, it is presumed that different parts of the plant and the methods to be used in oil extraction will change the oil yield and the pharmaceutical effect of the oil. Therefore, in this study, three different parts of Laurus nobilis which are fruit, fruit seed and fruit peel were extracted by cold pressed and Soxhlet methods and their fatty acid profiles were analyzed by GC-FID. The results show that the highest concentration of fatty acids belong to the laurel fruit extracted by soxhlet method consisting of 50.71% saturated fatty acids. The laurel peel extracted by cold pressed method follows it containing unsaturated fatty acids with a rate of 49.78%. Then the laurel seed extracted by soxhlet method follows it consisting of 40.40% saturated fatty acids. In this study, the effect of different extraction methods on the fatty acid ratios in the fruit, fruit seed and fruit peel parts of laurel was examined.
