Popis: | The methanol and acetone extracts prepared from Apium graveolens were tested to determine their antioxidant activities by using the ferric reducing antioxidant power (FRAP), the iron chelation activity, the 1,1-diphenyl-2-picrylhydrazyl radical (DPPH) scavenging activity and the superoxide radical scavenging activity. The contents of total phenolic compounds in the two extracts were measured using a Folin-Ciocalteu assay. As a result, methanol showed the best antioxidant effect in comparison with acetone extract. Superoxide scavenging activity in A. graveolens rose above 80% at 1000 mg/ml for both acetone and methanol extracts. The FRAP was more important with methanol extract (65%) compared with that of acetone extract (40%). The dosage of the polyphenolic components showed that phenol acids, tannins and flavonoids concentrations were higher in methanol extract than in acetone extract. |
