摘要

A persistent lack of comprehensive data on the nutritional value, phytochemical composition and, safety of wild leafy vegetables contributes to their neglect and underutilization. This study aimed to evaluate the nutritional composition, phenolic and flavonoid contents, antioxidant and antimicrobial activities, and acute toxicity of Portulaca oleracea, Malva sylvestris, and Chenopodium album, three neglected wild leafy vegetables traditionally consumed in Morocco. The analyzed species were rich in proteins, ash, and essential minerals, particularly iron, magnesium, calcium, and manganese. High levels of phenolic and flavonoid compounds were observed, accompanied by strong antioxidant activities as evidenced by DPPH, ABTS, and FRAP assays. The extracts also showed inhibitory effects on the growth of the tested bacterial strains. Acute oral toxicity assessment revealed no adverse effects, with LD50 values exceeding 5000 mg/kg. These findings highlight the nutritional potential and in vitro bioactivities of these species and support their potential for further investigation and valorization within local food systems.
