Özet
In this study, we determined the antioxidant activities of four different solvent fractions obtained from Freshliver plant leaves (Salvia officinalis) by employing two different assays such as 2,2-diphenyl-1-picrylhydrazyl hydrate (DPPH) and Folin-Ciocaltaeu method. The results showed that ethanol-extract of freshliver plant exhibited the highest total phenolic contents mg GAE/g extract; 43,55, methanol-extract of 23.62, ethyl acetate extract 18.29, and acetone extract 11.58. All the extractions showed almost similar free radical removal activities as inhibition of DPPH method. The values were found for methanol extract % 90.89, ethyl acetate extract, % 90.48, ethanol extract % 86.31 and acetone extract % 84.78.
Abstract
In this study, we determined the antioxidant activities of four different solvent fractions (ethanol, methanol, acetone and ethyl acetate) obtained from Freshliver plant leaves (Salvia officinalis) by employing two different assays such as 2,2-diphenyl-1-picrylhydrazyl hydrate (DPPH) and Folin-Ciocaltaeu method. The results showed that ethanolextract of freshliver plant exhibited the highest total phenolic contents (43.55 mg GAE/g extract), followed by methanol-extract of freshliver plant (23.62 mg GAE/g extract), ethyl acetate extract (18.29 mg GAE/g extract) and acetone extract (11.58 mg GAE/g extract). All the extractions showed almost similar free radical removal activities as % inhibition of DPPH method. The values were found for methanol extract % 90.89, ethyl acetate extract, % 90.48, ethanol extract % 86.31 and acetone extract % 84.78.
