Abstract
The study was conducted to assess the content (mg kg -1 fresh wt.) of macro, trace and toxic elements in the 4 different edible wild plants. The percentage of dry matter and ash ranged from 6.77 to 20.56 and 0.79 to 2.26, respectively. The contents of Ca (1074), Fe (160.5), Mn (18.21), Ni (6.11), B (2.61), Cr (0.93), Co (0.50), Mo (1.80), Be (0.009) and Se (0.076) of U. diocia were richer than in other plants. Other hand, K (7742), Mg (954), Al (10.79), V (9.77) and Ag (0.109) in T. orientalis , Zn (12.47), Cu (9.98) and Ba (130.3) in O. umbellatum were taken the highest value. Also As, Hg, Tl, Cd and Pb were determined mg kg -1 level in fresh plants. Conversely, antimony (Sb) in wild plants could not be detected by ICP-MS. The results of statistical analysis of forty plants showed that moisture, total dry matter, ash, K, Ca, Mg, Fe, Zn, Cu, Mn, Ba, Ni, Al, V, B, Cr, Co, Mo, Be, Se, Ag, As, Tl, Cd and Pb contents were varied significantly compared to plant species except for Na and Hg (p<0.05). Consequently, wild plants may be used as popular vegetables in many people diet as a source of minerals (Fe, Cu, Mn, Cr, Mo, K, Zn and Mg). Excessive plant consumption may be adversely affected human health with Cd, As, Hg, Tl and Pb.
Highlights
The number of edible plants on earth is known to be about 70000, today people use about 7000 plant species for food, medicine and other needs
Amount of Sb from the toxic elements in majority of samples was below detection limit
A large variation in minerals among plant species were observed from the coefficients of variation (14.7-138.6%)
Summary
The number of edible plants on earth is known to be about 70000, today people use about 7000 plant species for food, medicine and other needs. Distribution of edible wild plants on the earth depending on the climate is quite varied. Turkey is one of the richest natural resource for wild plants and has nearly 9000 plant species, of which 3000 are endemic [2, 3]. The demand for wild plants is increasing day by day due to the idea of positive impact on human health. Wild plants all over the world have an important place in agricultural production many industrial sectors (agricultural struggle, pharmaceutical, beekeeping, textiles etc.). The protection of wild genetic resources for agricultural production is another important issue [2, 3]. Harvesters and manufacturers should be responsible for the conservation of plant species for the continuation of biodiversity
