采用硫代巴比托酸活性物质（TBARS）法对葡萄牙北部地区两种传统栽培蔬菜的化学成分、营养成分和体外抗氧化性能进行了测试，采用四种测定方法：2,2-二苯基-1-苦味酰肼（DPPH）自由基清除活性、还原能力、抑制β -胡萝卜素漂白和抑制脂质过氧化。研究的两种芸苔属植物品种，在当地被称为“grelos”（油菜）和“espigos”（“龙眼”卷心菜），是营养均衡的蔬菜；尤其是“龙尾”卷心菜，其水分、蛋白质、脂肪、能量、β -胡萝卜素和维生素C含量最高；油菜的灰分、碳水化合物、糖（包括果糖、葡萄糖、蔗糖和棉子糖）、必需n-3脂肪酸α -亚麻酸含量最高，PUFA/SFA和n-6/n-3脂肪酸、生育酚、番茄红素、叶绿素、酚类物质、类黄酮含量最佳，抗氧化性能也最高。与抗氧化特性相关的健康益处加强了它们对健康和均衡饮食的贡献，突出了它们的消费兴趣，验证了经验性使用，并为长期使用的传统/地区产品增添了新的价值。(C) 2011 Elsevier Ltd.版权所有。
Two traditional cultivated vegetables highly consumed among Northern Portuguese regions were tested for their chemical composition, nutritional profile and in vitro antioxidant properties using four assays: 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals scavenging activity, reducing power, inhibition of beta-carotene bleaching and inhibition of lipid peroxidation by thiobarbituric acid reactive substances (TBARS) assay. The studied varieties of two Brassica species, locally known as "grelos" (rape) and "espigos" ("tronchuda" cabbage) are nutritionally well-balanced vegetables; particularly "tronchuda" cabbage revealed the highest levels of moisture, proteins, fat, energy, beta-carotene and vitamin C; rape gave the highest contents of ash, carbohydrates, sugars (including fructose, glucose, sucrose and raffinose), essential n-3 fatty acid alpha-linolenic acid, and the best ratios of PUFA/SFA and n-6/n-3 fatty acids, tocopherols, lycopene, chlorophylls, phenolics, flavonoids, and also the highest antioxidant properties. The health benefits associated to the antioxidant properties reinforce their contribution to a healthy and balanced diet, highlight the interest of their consumption, validate the empirical use and add new values to traditional/regional products which have been used for a long time.
