Antioxidant activity and mineral ingredient assessment of different solvent extracts of paronychia chionaea

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 micro g GAE / mg extract) when compared to the methanol extract (98.72 +- 6.06 micro g 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 chionaeamethanol extract were 2.84 +- 0.3 micro molTroloxEq/g and 6.56 +- 0.8 micro mol H/sub 2/O/sub 2/Eq/g, respectively and the total antioxidant and oxidant status of acetone extract were 2.68 +- 0.4 micro molTroloxEq/g and 6.22 +- 0.6 micro mol H/sub 2/O/sub 2/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. (author)
