Lipid composition was determined in the separated seeds and pulp + peel of grape cv. Fortana. Tabulated results reveal important differences in composition. The seed oil contained 9.7% palmitic, 6.8% stearic, 20.5% oleic and 63.0% linoleic acid (vs. 11.7, 2.9, 19.0 and 34.0% in the pulp + peel); 1.5% cholesterol, 12.6% campesterol, 12.2% stigmasterol and 72.0% beta-sitosterol (vs. 0.6, 5.0, 3.8 and 88.1%, as well as 2.5% 7 stigmasterol, 11.4% erythrodiol and 2.6% uvaol, the last 2 not found in seed oil). The methylsterol fraction of the seed oil showed no known compounds, while pulp + seed contained only oleanoic and ursolic acid. Significant differences were also found in the alcohol (linear and terpene) and hydrocarbon fractions.
