title: Impact of Cultivar on Profile and Concentration of Lipophilic Bioactive Compounds in Kernel Oils Recovered from Sweet Cherry (Prunus avium L.) by-Products.
abstract: Lipophilic bioactive compounds in oils recovered from the kernels of seven sweet cherry (Prunus avium L.) cultivars, harvested at single location in 2013, were studied. Oil yield in sweet cherry ranged between 30.3-40.3 % (w/w) dw. The main fatty acids were oleic acid (39.62-49.92 %), linoleic acid (31.13-38.81 %), α-eleostearic acid (7.23-10.73 %) and palmitic acid (5.59-7.10 %), all four represented approximately 95 % of the total detected fatty acids. The ranges of total tocochromanols and sterols were between 83.1-111.1 and 233.6-419.4 mg/100 g of oil, respectively. Regardless of the cultivar, the γ-tocopherol and β-sitosterol were the main lipophilic minor bioactive compounds. The content of the carotenoids and squalene were between 0.38-0.62 and 60.9-127.7 mg/100 g of oil, respectively. Three significant correlations were found between oil yield and total contents of sterols (r = -0.852), tocochromanols (r = -0.880) and carotenoids (r = -0.698) in sweet cherry kernel oils. The oil yield, as well as the content of lipophilic bioactive compounds in oil was significantly affected by the cultivar.
