摘要:
The aim of this study was to assess the possible antioxidant activities of 80% methanolic extract from the Inula graveolens L. plant. It was found that the methanolic extract has the highest content of phenolic (1.63%, calculated as gallic acid) and flavonoid (0.52%, calculated as quercetin) equivalents per 100 g of dry mass. The methanolic extract possesses strong antioxidant activity (64.28%) as well as strong reducing power (increasing as the extract concentration increases) and ferrous ion chelating (96%) abilities. Moreover, the methanolic extract shows the highest free radical-scavenging activities for superoxide anion and hydroxyl radical, reaching 93.43% and 91.38%, respectively.
