In this study, analysis of trace elements (Al, V, Cr, Ni, Cu, Zn, As, Ag, Cd, Sn, Hg, Pb) of taxa, such as Alkanna trichophila Hub.-Mor. var. trichophila, Anchusa azurea Mill. var. azurea ( Boraginaceae ), Achillea biebersteinii Afan., Centaurea iberica Trev. ex Sprengel (Asteraceae), Ajuga vestita Boiss.(Endemic), Teucrium polium L. ( Lamiaceae ) by ICP-MS technique, collected in Çermik district of Turkey's Diyarbakır province and used for folk or medicinal purposes, was conducted quantitatively and qualitatively using the ICP-MS technique. As a result of the analysis, Sn, Hg, Pb elements in all six plant taxa could not be determined since they were below the lod value. It is essential for consumers that these three toxic elements are not specified in plant species. The highest concentration was determined in element Al (26.04-193.5 mg/kg). With this study, some metal characterisations and concentrations of medicinal plants were determined.

Organic farming is a human and environment friendly production system that is based on soil fertility and food safety without using chemical fertilizers and pesticides in production, aiming to re-establish the deteriorated ecological balance as a result of harmful production practices. Organic products attract the interest of consumers as they are strongly perceived as healthier products compared to conventional food. This study aimed to determine the differences in chemical, mineral, and fatty acid characteristics between conventionally and organically cultivated Ferragnes and Ferraduel almond cultivars. When conventional and organic almonds were evaluated in terms of fatty acids, proximate compositions, and minerals, crude oil and Mg were statistically insignificant, while Cu was significant (P < 0.05) and all others were quite significant (P < 0.001). Total sugar was higher in organic samples compared to conventional samples in both cultivars. The crude oil and linoleic acid (12.93% for Ferragnes and 14.99% for Ferraduel) were higher in conventional samples but oleic acid (78.9% for Ferragnes and 81.08% for Ferraduel) was higher in organic samples. In addition, organic samples contained higher Mg and Fe but lower P, K, Ca, Na, Zn, Mn and Cu when compared with conventional samples. The results indicate that conventionally cultivated almonds present higher mineral content and lower fatty acid value compared to organically cultivated almonds.
