The possibility of grape seeds as industrial resources was tested by analyzing various chemical proper-ties of their oils from seven different species. The range of crude oil content of the grape seeds was 26.0-32.0% showing the highest content in Steuden, Mean individual fatty acid contents in the grape seeds were lioleic (70.75%) oleic (18.48%) stearic (2.01%) and palmitic (8.45%) acids. Stearic acid was low in Jingyu and high oleic acid was found in Fugiminori compared with other grape strains. Total lipirds were consisted of nutral lipid (87.25%) glycolipid(4.68%) and phospholipid *8.06%) Content of crude proteins was approximatery 11.2% with some variation between strains. Total sugar content was 2.35~5.63$mu$g/mg with reducing sugar 3.20$mu$g/mg. Mean saponification value of crude oils was 186.3mg.KOH.oil Antioxidant activity of grape seed oils was better than that of sesame oil resulting in the hi-oils and sesame oil after heat treatment at 18$0^{circ}C$.
