“…[14,15] Tunisia is a Mediterranean country with various bioclimatic zones ranging from humid to Saharan regions with a wide biodiversity of plant resources. [16] Among them, halophyte plants, living in extreme environments with huge variations in salinity, drought, precipitation and temperatures, produce various enzymes, molecules and bioactive compounds. Alternative medicine, especially in rural areas, uses leaves and roots of these plants to treat various diseases, microbial and viral infections and aging processes.…”

A particular interest is nowadays given to natural antioxidants occurring in foods which can reduce the risk of several diseases through their protective effect. The genus Limonium is widely distributed in different salt regions of Tunisia and known in traditional medicine for the presence of highly effective viral and bacterial replication inhibitors. Limonium leaves have possible beneficial effects on human health for their antioxidant activities and free radical scavenging abilities. To exploit the potential of plants from extreme environments as new sources of natural antioxidants, we studied the extracts from leaves of eight Limonium species growing in extreme environments in Tunisia. Antioxidant molecules (polyphenols, flavonoids, flavonols, ascorbate, tocopherols), in vitro (DPPH, ORAC) and ex vivo antioxidant potential on human erythrocytes, antioxidant enzymes activities (superoxide dismutase, peroxidases, glutathione reductase) were evaluated to identify the species with the best antioxidant capacity. The results showed variability among the species considered in function of the environmental conditions of their natural biotopes, as for the antioxidants measured. In particular, L. vulgare from Oued Rane biotope, characterized by dryness and high temperatures, was the species with the highest enzymatic activity and antioxidant capacity, making it interesting as possible edible halophyte plant or as food complement.

“…Foreigners cannot own agricultural land but may obtain long-term leases. Agriculture is also not the most important business in Tunisia as can be derived from the fact that approximately 16% of the country's workforce is engaged in the agricultural sector, and agriculture contributes about 12% to the country's GDP 10 .…”
