Abstract :
Caper (Caparis spinosa L.) is a herbaceous and perennial plants belonging to the Capparidaceae family. The different species of Caparis are valuable plants which have used as a medicine, food and spices. This research was conducted for evaluation of oil percent and fatty acids composition of some caper genotypes in several regions of south Iran. Oil extraction and determination of fatty acids were done by Soxhlet and Gas Chromatography, respectively. The oil percent in studied genotypes varied from 21.10% (Dashte-arzhan genotype) to 29.70% (Noor Abad genotype). In caper seed oils, 12 different fatty acids were identification. The highest amounts of saturated fatty acids were related to palmitic (C16:0) and stearic acids (C18:0). Also, linoleic acid C18:2(n-6), oleic acid C18:1(n-9) and plmitoleic acid (C16:1) were the main unsaturated fatty acids. The highest amount of linoleic acid (46.74%), palmitoleic acid (2.93) and oleic acid (37.92%) were observed in Noorabad, Kaskan and Parishan genotypes, respectively. The highest and the least value of unsaturated fatty acids were measured in Saadat-shahr and Ghaleh-sefid genotypes. In over all, according to obtained results, there are noticeable variation were observed among caper genotypes in terms of oil percent and fatty acid components. Seed oils of caper due to possess noticeable unsaturated fatty acids, which are important role on human health can be consideration as plants oil resources.
