Abstract
The present study was conducted to determine total phenolic content, DPPH free radical scavenging properties, total antioxidant/oxidant status and mineral substance content of methanol and acetone extracts of endemic Paronychia chionaea species. The findings indicated that the phenolic substance content was higher in acetone extract (112.76 ± 8.4 μg GAE / mg extract) when compared to the methanol extract (98.72 ± 6.06 μg GAE / mg extract). It was observed that the radical scavenging effect of Paronychia chionaea methanol extract (70.5%) was similar to that of the synthetic antioxidant BHT (74.8%) and higher than the effects of the acetone extract (59.8%). The total antioxidant and oxidant status of the Paronychia chionaea methanol extract were2.84 ± 0.3 μmol Trolox Eq/g and 6.56 ± 0.8 μmol H2O2 Eq/g, respectively and the total antioxidant and oxidant status of acetone extract were 2.68 ± 0.4 μmol Trolox Eq/g and 6.22 ± 0.6 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, Paronychia chionaea was with high bio-value. The present study is considered to provide information for future studies.
