Abstract

In this study, phytosterol content and fatty acid composition of grape seeds from fourteen different cultivars produced in Korea were determined. Although the total phytosterol contents depended upon the cultivars, the major phytosterol was $\beta$-sitosterol (64.9$\sim$119.3 mg/100 g) in all samples. The fatty acid composition of the grape seeds were analyzed as palmitic (16:0, 6.8$\sim$16.8%), palmitoleic (16:1, 0.1$\sim$0.2%), stearic (18:0, 4.7$\sim$5.2%), oleic (18:1, 16.6$\sim$26.1%), linoleic (18:2, 16.6$\sim$20.1%), linolenic acid (18:3, 0.3$\sim$0.5%) and arachidic acid (20:0, 0.3$\sim$0.5%). Campbell early, the mainly produced and consumed cultivar in Korea, contained relatively high phytosterol content compared to other samples and high proportion of unsaturated fatty acids. Therefore, the seeds from Campbell early might be used for functional oil production and as food ingredients.
