Abstract
The present study aims to determine the micronutrients content of six wild edible plants (Malvasylvestris, Portulaca oleracea, Silene vulgaris, Nasturtium officinale, Emex spinosa, and Scolymus hispanicus) usedas wild vegetables in the Al-Haouz, Morocco. Macroelements (Ca, Mg, Na, P, K, and S) and microelements(Cu, Mn, Fe, Zn, and B) were analyzed by the inductively coupled plasma - optical emission spectrometry(ICP-OES). The results showed that the assessed wild species are very rich in micronutrients. The Zn andS contents were significantly higher in Nasturtium officinale (P<0.05) compared to other species, while Emexspinosa has the highest level of Na, Mg, Ca, and Mn. On the other hand, the Fe content was important inScolymus hispanicus, Emex spinosa and Nasturtium officinale (1833.3 mg/kg, 1338.8 mg/kg and 1333.4 mg/kg,respectively). Finally, these wild species seem to be important nutritional resources and food supplementsin the human diet.
