Abstract :In this study, sage insert ignore into journalissuearticles values(Salvia officinalis L.);, linden insert ignore into journalissuearticles values(Tilia platyphyllos Scop.);, and daisy insert ignore into journalissuearticles values(Matricaria chamomilla L.); herbs, which have rich phytochemical content and are frequently consumed in winter months for medicinal purposes, were obtained from three different herbalists located in Bingol and investigated in terms of their heavy metal contents, total flavonoid, total anthocyanin and total polyphenol contents. Some of the heavy metal insert ignore into journalissuearticles values(Cr, Fe, Co, Ni, Cu, Zn, As, Hg, Pb); contents of the collected herb samples were determined by ICP-MS. Total flavonoid, total anthocyanin and total polyphenol contents were determined by analyzing spectrophotometric methods. While the total phenolic content was found the most in sage insert ignore into journalissuearticles values(S1); ethylacetate and methanol extracts insert ignore into journalissuearticles values(760.1±2.0, 410.33±1.5 mg GAE/g);, it was found the least in linden insert ignore into journalissuearticles values(L1, L3); hexane extracts insert ignore into journalissuearticles values(6.66±.1.3, 8.35±0.8 mg GAE/g);. It was determined that total flavonoid content and total anthocyanin contents were higher in sage insert ignore into journalissuearticles values(S1); ethylacetate insert ignore into journalissuearticles values(294.31±2.1 mg CE/g and 291.31±2.1 mg MvGE/g);, sage insert ignore into journalissuearticles values(S2); methanol insert ignore into journalissuearticles values(375.0±1.9 mg CE/g and 139.01*±2.0 mg MvGE/g); extracts, and less in linden insert ignore into journalissuearticles values(L1); and daisy insert ignore into journalissuearticles values(D1); hexane extracts respectively. It was determined that Cr and Cu metals were among the values suitable for consumption in terms of health in all samples except the chamomile insert ignore into journalissuearticles values(D1, D3); samples, and Zn metals were among the values suitable for consumption in all samples except the linden insert ignore into journalissuearticles values(L2); sample. Furthermore, the toxic metal Cd insert ignore into journalissuearticles values(0.05±0.00- 0.09±0.00 μg/g); in daisy insert ignore into journalissuearticles values(D1, D3); samples, as well as the other toxic metal Pb insert ignore into journalissuearticles values(4.50±0.01-6.43±0.01 μg/g); in sage insert ignore into journalissuearticles values(S1,S2,S3); and linden insert ignore into journalissuearticles values(L1,L2,L3); samples, were found to be among the values suitable for consumption in terms of health. As a result, when the total anthocyanin, polyphenol and flavonoid contents were compared in all groups it was found that sage had the highest value in ethyl acetate extract. Additionally, Cu and Ni values of sage, and Fe and Pb values in both sage and linden were within safe limits in terms of health. They are of utmost importance in terms of supporting the daily mineral intake. However, As, Pb, and Hg were found to be toxic in daisy extract. This result can be shown as a result that the daisy will be a bioaccumulator. Therefore, consumption of daisy tea should be limited.
