Feverfew (Tanacetum parthenium L.) is a shrub from Asteraceae family that spread all over Iran, which have several therapeutic properties like as anti-septic, antimicrobial and antioxidant properties. The main objective of this study was to evaluate the antioxidant activity of shoot extract of feverfew. After preparation of different extracts such as hexane, ethyl acetate and methanol of feverfew, their antioxidant properties were measured by two methods, DPPH and FRAP. BHT and vitamin C were used as positive control for comparison. In this study, the amount of phenols and flavonoids were also measured. The results showed that the total phenol and flavonoid content of the methanolic extract was higher than other extracts. However, it was a direct relationship between flavonoid and phenolic content and antioxidant activity. Antioxidant activity was dependent on concentration and the highest antioxidant activity was observed in methanolic extract and the lowest activity in the ethyl acetate extract. The more antioxidant activity of extracts was obtained in the higher concentration, Furthermore the results showed that flavonoids and phenolic compounds had a major role in the antioxidant activity and more studies are needed for the isolation and purification of specific active components of this plant.
