Abstract
The antioxidant and inhibitory effects of methanol and aqueous extracts from Hymenogaster aromaticus, Ramaria aurea, and Rhizopogon luteolus against cholinesterase, tyrosinase, alpha-amylase, and a-glucosidase are reported here, to our knowledge for the first time. Antioxidant activities were investigated using different assays, including 2,2-diphenyl-1-picrylhydrazyl, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid), ferric ion-reducing antioxidant power, cupric ion-reducing antioxidant capacity, phosphomolybdenum, and metal-chelating assays. In general, the highest antioxidant and enzyme-inhibitory effects were observed in methanol extracts, which had the highest concentrations of phenolics. (+)-Catechin, benzoic acid, and p-hydroxybenzoic acid were determined to be the main phenolics in H. aromaticus components both in methanol and in aqueous extracts, whereas the other 2 species present very different phenolic fingerprints, also at smaller quantities. These results suggest that these mushroom species may be considered sources of natural agents.
