摘要
Natural compounds with antioxidant activity can be useful for treatment of reactive oxygen species-related diseases, comprising atherosclerosis, inflammatory injury, cardiovascular disease, cancer, diabetes, Alzheimer's disease, cataracts, autism, and aging. The current study was perform to assay the antioxidant activity different fractions of methanolic extract of golden chanterelle mushroom Cantharellus cibarius, a mushroom found in the north of Iran. Different fractions of methanolic extract of this mushroom, including n-hexane, chloroform, ethyl acetate, n-butanol, and water, were evaluated for antioxidant activity using six in vitro assay systems. Mushroom fruit was obtained from the local market, Sari (northern Iran). The n-hexane fraction had higher amounts of flavonoids contents (40.01 ± 1.30 mg quercetin equivalent g−1 of extract) and the highest exhibition of nitric oxide scavenging activity (77.21 ± 1.48%). The highest content of phenol was observed in the n-butanol fraction, which was 40.97 ± 0.99 mg gallic acid equivalent g−1 of extract. Among all the fractions, the ethyl acetate fraction was found to show higher DPPH scavenging activity (33.43 ± 1.30%) and the aqueous fraction to display the most reducing power. The highest Fe2+ chelating activity was observed in the chloroform fraction and then in the n-hexane fraction (86.13 ± 1.61 and 80.68 ± 2.07, respectively). The results all together signify C. cibarius as a valuable source of natural bioactive compounds with antioxidant activity.
