Abstract

The study was done on 23 types of Sourani cultivar, chosen from six sites in Idleb, the results showed that the oil concentration on wet basis ranged between 17% and 33.6%, and the oils of all types conformed to the IOC specifications concerning acidity, peroxide value, U.V. absorbency, and fatty acid composition. The percentages of Oleic acid ranged between 55.8% and 71.9%, and the percentages of Triolein between 18.8% and 37.6%, total sterols ranged between 777and 1631 mg/kg, and were under the international limit (1g/kg) in seven types, while -∆ 7 Stigmastenol was above the limit (0.5% of total sterols) in seventeen types. Total phenols ranged between 261 and 750 ppm, and the waxes content was generally low (51-86) ppm. The studied types were classified into three groups using cluster analysis based on the triglycerides content.

Keywords: Sorani cultivar, olive oil, fatty acids, glyceride, sterols, phenols, waxes.
