对6种核桃（Juglans regia L.）对从马特尔（突尼斯北部）收集的栽培品种（Lauzeronne、Franquette、Hartley、Local pt、Local gd和Parisienne）进行评价。核桃油中主要脂肪酸为亚油酸（60.42 - 65.77%）、油酸（13.21 - 19.94%）和亚麻酸（7.61 - 13%）。TAG种类主要由三亚油酸甘油酯（LLL）、二亚油酰-亚麻酰-甘油、二亚油酰-油酰-甘油和棕榈酰-二亚油酰-甘油类组成。结果表明，地方品种油分、亚油酸和低LL含量最高，分别为62.56%、65.77%和33.48%。油样品之间的显着差异进行了观察，因此，品种之间的油成分表现出很大的变化。
The chemical composition (total oil content, fatty acids, triacylglycerols (TAGs) and polar compounds) of six walnuts (Juglans regia L.) cultivars (Lauzeronne, Franquette, Hartley, Local pt, Local gd and Parisienne) collected from Mateur (north of Tunisia) was evaluated. The major fatty acids found in the walnut oils are linoleic acid (60.42-65.77%), oleic acid (13.21-19.94%) and linolenic acid (7.61-13%). The TAG species were mainly composed of trilinolein (LLL), dilinoleoyl-linolenoyl-glycerol, dilinoleoyl-oleoyl-glycerol and palmitoyl-dilinoleoyl-glycerol classes. The results revealed that Local pt variety has the highest level of oil (62.56%), linoleic acid (65.77%) and LLL (33.48%). Significant differences among oil samples were observed, therefore showing a great variability in the oil composition among cultivars.
