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.

Abstract

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.
