Background: Plants are an important source of antioxidants that can help to cell’s normal metabolism via preventing accumulation of free radicals and so, prevent developing diseases associated with oxidative stress. Thus, the present study was performed to determine the antioxidant properties of Artemissia Annua extracts (AA).
Methods and materials: at first, Artemisia Annua with a local name as Gandvash identified and then some parts of its leaves and flowers into powder. Extracting was done using water, ethanol and methanol solvent. FRAP assay was performed to determine the antioxidant properties. For this purpose, extract solutions with 20% concentration were added to FRAP solution and after incubation, the optical absorption values was measured. The ferrous sulfate and vitamin C were used as standard solutions.
Results: the Mean total antioxidant capacity (TAC) for methanolic leaves extract was 72.18 ± 4.18 micro mol ferrous sulfate and 90.31 ± 5.27 mg of vitamin C per gram of dry weight, which is considerably higher than other extracts (p0.05) while, the ethanol extract of the leaves and flowers were different significantly (p
