In this study, Salvia verticillata L. subsp. amasiaca, Salvia aethiopis L. and Salvia sclarea L. grown together under cultivated conditions were used as plant material and minerals and bioactive content (antioxidant activity, total phenolic content, and total flavonoid content) of the aerial parts, flowers, and leaves of the species were determined. Results indicated that K, Ca, and P were the main macrominerals with concentration of 496-1148 ppm for K, 157-938 ppm for Ca and 63-127 ppm for P, respectively. The highest Ca content was obtained in the leaves for all Salvia species. The amount of three heavy metals (Cd, Cr and Ni) in Salvia samples was found to be lower than the maximum allowed amount by the WHO/FDA for these heavy metals. Considering the three Salvia species, the highest Na was determined in the flower part. Leaf extract of S. verticillata L. subsp. amasiaca had the highest radical scavenging activity as 51.16 mu g/mL and the highest total phenolic content (131.62 mu g gallic acid equivalent/g). The highest total flavonoid content was obtained from S. sclarea flower extract.
