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.

Abstract
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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
