Investigation of total antioxidant and total oxidant activities and mineral content of some herbal teas used for therapeutic purposes

In this study, the presence of heavy metals and the differences in oxidant-antioxidant activity were investigated in a total of 80 samples, 20 of which were used for medicinal purposes (sage, linden, thyme, green tea) herbalists/markets in Afyonkarahisar and Kütahya city centers. Metal contents were determined using the ICP-OES instrument. As a result of the research, although it was determined that the plant samples did not contain arsenic (As), antimony (Sb), selenium (Se), different levels of Be, Cd, Cr, Co, Cu, Fe, Pb, Li, Mg, Mn, Mo, Ni, Sr, Tl, Ti, V, Zn It was seen at the end of the analysis that it contains. Be level (0.041-0.068), Cd level (0.025-0.055), Cr level (0.387-1.789), Co level (0.090-0.476), Cu level (6.62-21.48), Fe level (78.80-170.46), Pb level (4.33-8.88), Li level (1.19-5.84), Mg level (124.38-194.4), Mn level (34.56-76.24), Mo level (0.28-2.27), Ni level (0.73-9.89), Sr level (15.77) -52.96), Tl level (2.81), Ti level (2.80-22.35), V level (0.46-1.29), and Zn level (18.05-44.06) were determined in the ppm range. In the study, the levels of Total Antioxidant Status (TAS), Total Oxidant Status (TOS) and Oxidative stress index (OSI) were examined. TAS value was determined in the range of 3.56-3.76, TOS value was determined in the range of 27,26-201.32, OSI value was determined in the range of 7.36-53.65. As a result, the unconscious use of herbal teas should be avoided, it should be known that if not used carefully, it can cause bad results in terms of health and certain standards should be set for human nutrition for each plant species.
