Oil yields, fatty acid compositions and tocopherol contents of grape seed oils from Turkey

In the present study, the oil contents, fatty acid composition and tocopherol contents of grape seed and corresponding oils were analyzed by using Gas Chromatograph and High Performance Liquid Chomotography. The results showed that the oil concentration of seeds ranged from 7.9 to 20.1 % Grape seed oils were rich in oleic and linoleic acids, ranging from 12.9 to 27.1 % and 58.3 to 74.8 %, respectively. In addition, A few types of tocopherols were found in grape seed oils in various amount: ?-tocopherol, ?-tocotrienol, ?-tocopherol, ?-tocotrienol and ?-tocotrienol. As a result, present study shows that oil, fatty acid composition and tocopherol contents differ significantly among the cultivars.
