Total Phenolic Content, Antioxidant Properties and Element Concentrations of Methanol and Acetone Extracts of Stachys tmolea Boiss.

Abstract

DPPH radical scavenging, total antioxidant status, phenolic and element concentrations of the different solvent extracts of Stachys tmolea Boiss. were determined in the study. It was found that, the methanol extract of the plant contains total phenolic substance is 68.91±1.4 mg Gallic acid equivalant/g extract. % DPPH radical inhibition was 64.79±1.98 and total antioxidant status was 2.28±0.21 mmol Trolox Equiv./L. The acetone extract contains total phenolic substance (27.26±1.2 mg GAE/g extract). % DPPH radical was 50.33±2.05, and total antioxidant status was 0.57±0.04 mmol Trolox Equiv./L. It is seen that, the methanol extract has properties close to the synthetic antioxidant butylated hydroxy anisole (total phenolic substance concentration is 82.33±2.1 mg GAE/g). It is determined that the species also contains elements such as Cu, Mn, and Fe that participate in superoxide dismutase and catalase. In conclusion, the methanolic extract of Stachys tmolea exhibits radical scavenging and antioxidative properties. The species is thought to be a plant that can evaluate in phytotherapy studies due to the important elements it contains.
