The present investigation was designed to evaluate the physicochemical properties of two type of Shahrodi grape seed oil (Lal and Khalili) which extracted by Soxhlet methods and petroleum ether as solvent. The physicochemical properties considered as response variables were: cloud percentage of extraction, peroxide value, acidity, soapy number, fatty acid and non soapy material. The results indicated that Lal grape seed oil showed the lower peroxide value and higher percent of oil extraction than Khalili grape oil. The results of this study indicated that the most content fatty acid in the seed oils of Lal and Khalili grape was linoleic acid, ranging from 63.17 % and 65.39 % of total fatty acids respectively.Also, The grape seed oils were contained low level of saturated fatty acid and high percentage of oleic acid and which are healthy and have beneficial effect on reducing cholesterol level.
