Three wild edible plant species belonging to the Asteraceae family, Crepis vesicaria L. (s.l.), Sonchus asper (L.) Hill s.l., and Sonchus oleraceus L., usually consumed in the Mediterranean diet, were tested for their nutritional composition and content of carotenoids, tocols, thiamine and riboflavin. Low amounts of thiamine and riboflavin were found. All species were sources of xanthophylls (violaxanthin, neoxanthin, lutein, zeaxanthin and β-cryptoxanthin) and carotenes (α-carotene, β-carotene, 9-cis-β-carotene and 13-cis-β-carotene). Lutein accounted for the highest content (about 4 mg/100 g). They had good tocol amounts, in particular α-tocopherol (about 2-3 mg/100 g). Taking into account the Recommended Daily Allowance (RDA) established by the EU Regulation, the analyzed plants can be declared as a source of fiber, vitamin A and E. These data could be useful for database on the nutritional and bioactive compound profile of studied plants and can contribute in promoting their use in functional foods.
三种属于菊科的野生食用植物，即垂头菊属（广义）、苦苣菜属（广义）和苦荬菜，通常被纳入地中海饮食中，它们的营养成分和类胡萝卜素、生育酚、硫胺素和核黄素含量已被测试。结果表明，这三种植物的硫胺素和核黄素含量都较低。所有这些植物都含有叶黄素（堇黄质、新黄质、叶黄素、玉米黄质和β-隐黄质）和类胡萝卜素（α-胡萝卜素、β-胡萝卜素、9-顺式-β-胡萝卜素和 13-顺式-β-胡萝卜素）。叶黄素的含量最高（约 4mg/100g）。它们还含有丰富的生育酚，特别是α-生育酚（约 2-3mg/100g）。根据欧盟法规规定的每日推荐摄入量（RDA），这些分析植物可被宣布为纤维、维生素 A 和 E 的来源。这些数据可以为研究植物的营养和生物活性化合物特征的数据库提供参考，并有助于促进它们在功能性食品中的应用。
