Oils extracted from Cucurbitaceae seeds were characterised for their fatty acid and tocopherol compositions. In addition, some physicochemical characteristics, total phenolic contents and the radical-scavenging activities were determined. Oil content amounted to 23.9% and 27.1% in melon and watermelon seeds, respectively. Physicochemical characteristics were similar to those of other edible oils and the oils showed significant antioxidant activities. Fatty acid composition showed total unsaturated fatty acid content of 85.2-83.5%, with linoleic acid being the dominant fatty acid (62.4-72.5%), followed by oleic acid (10.8-22.7%) and palmitic acid (9.2-9.8%). The oils, especially watermelon seed oil, showed high total tocopherol and phenolic contents. The γ-tocopherol was the predominant tocopherol in both oils representing 90.9 and 95.6% of the total tocopherols in melon and watermelon seed oils, respectively. The potential utilisation of melon and watermelon seed oils as a raw material for food, chemical and pharmaceutical industries appears to be favourable.
对葫芦科种子提取的油进行了脂肪酸和生育酚成分分析。此外，还测定了一些理化特性、总酚含量和自由基清除活性。甜瓜籽和西瓜籽的含油量分别为23.9%和27.1%。理化特性与其他食用油相似，且这些油具有显著的抗氧化活性。脂肪酸组成显示总不饱和脂肪酸含量为85.2 - 83.5%，其中亚油酸为主要脂肪酸（62.4 - 72.5%），其次是油酸（10.8 - 22.7%）和棕榈酸（9.2 - 9.8%）。这些油，尤其是西瓜籽油，显示出较高的总生育酚和酚含量。γ-生育酚是两种油中的主要生育酚，分别占甜瓜籽油和西瓜籽油中总生育酚的90.9%和95.6%。甜瓜籽油和西瓜籽油作为食品、化工和制药行业的原料具有良好的潜在利用价值。
