This study investigated the qualitative characteristics of several edible wild herbaceous species, including those most consumed in Foggia Province (southern Italy). Analysis was performed for parts 11 species (Beta vulgaris L., Foeniculum vulgare Miller, Centaurea solstitialis Cichorium intybus Scolymus hispanicus Sonchus oleraceus Borago officinalis Diplotaxis erucoides tenuifolia (L.) DC, Sinapis arvensis Portulaca oleracea L.) and three cultivated (C. intybus, B. officinalis, D. tenuifolia). The plants were collected from areas countryside, part each analysed dry matter, protein, cation anion contents as well total phenols antioxidant activities. Among cations, calcium differentiated among ranging 784 mg kg-1 fresh weight (Fw) to 5886 Fw S. hispanicus. nitrate also highly variable, 75 C. 3874 tenuifolia. Total polyphenols ranged 1054 GAE 3664 arvensis. Antioxidant activities 839 TE 5658 intybus. Significant differences noted between parameters. activity higher than their counterparts. Multivariate analysis (cluster linear discriminant analysis) allowed integration ANOVA data determine that contribute group differences. results present aims at improve current knowledges about vegetable sources Mediterranean diet.
