Determination of Afyon Endemic plant Sideritis Akmanii free radical scavening,the total phenolic substances, total anti-oxidant and an oxidant status and mineral matter content

Total phenolic content, DPPH free radical scavenging properties, total antioxidant/oxidant status and mineral substance contentof methanol and acetone extracts of the Sideritis akmaniispecies were determined in the present study. The findings indicated that the phenolic substance contentwas lower in acetone extract (117.72±6.4 μg GAE / mg extract) when compared to the methanol extract (144.08±2.01 μg GAE / mg extract). It was observed that the radical scavenging effect of Sideritis Akmanii methanol extract (73.2%) was similar to that of the synthetic antioxidant BHT (72.7%) and higher than the effects of the acetone extract (60.1%). The total antioxidant and oxidant status of the Sideritis Akmanii methanol extract were 2.34 ± 0.3 μmolTroloxEq / g and 4.88 ± 0.8 μmol H2O2 Eq/g, respectively and the total antioxidant and oxidant status of acetone extract were 2.38 ± 0.2μmolTroloxEq / g and 5.04 ± 0.5 μmol H2O2 Eq / g, respectively. Due to its Mn, Fe, and Cu content, which are minerals that are incorporated in the enzyme structure, its total phenolic substance levels, its antiradical properties and antioxidant/oxidant status, Sideritis Akmanii was considered a species with high bio-value. The present study is considered to provide information for future studies.
