N2 - Lipophilic bioactive compounds in kernel oils recovered from fruit pits of six sour cherry (Prunus cerasus L.) cultivars were studied. Oil yields ranged between 17.5-37.1%, with an average of 31.8%. The main fatty acids were linoleic (35.50-46.06%), oleic (25.25-45.30%), α-eleostearic (7.43-15.76%) and palmitic (5.06-7.38%), containing 94-96% of total detected fatty acids. The range of total tocochromanols was between 118.2 and 163.6 mg/100 g of oil. Independent of the cultivar, γ-T was the main tocochromanol and constituted between 61 and 83% of the total identified tocopherol and tocotrienol homologues in all studied samples. The total content of the carotenoids was between 0.51-1.75 mg/100 g of oil. The concentration of squalene in different sour cherry kernel oils was reached between 65.8-102.8 mg/100 g of oil. The concentration of sterols varied significantly for all of the studied cultivars and ranged between 313.6-1041.3 mg/100 g of oil. The β-sitosterol constituted 77-82% of the total sterol content detected in the samples studied. Two significant correlations were found between oil yield and the total content of sterols (r= -0.974, p≤. 0.001) and carotenoids (r= -0.915, p≤. 0.01) in sour cherry kernel oils.
