Abstract
Objective - to study the antioxidant activity of the extracts from fruiting bodies of fomitoid fungi growing in the Republic of Belarus.
Materials and Methods. Fruiting bodies of Piptoporus betulinus , Inonotus obliquus , and Fomes fomentarius were collected from silver birch; Ganoderma applanatum - from oak; Phellinus igniarius , Laetiporus sulphureus and Fomitopsis pinicola - from pine; and Ganoderma lingzhi was cultivated on an oak sawdust-based substrate. Total hydroalcoholic extracts were obtained using the remaceration method. For fractionated extracts, the crushed raw material was sequentially extracted in a Soxhlet apparatus using petroleum ether (40-70), chloroform, ethyl acetate, and 96% ethanol (rectified). The antioxidant activity of the extracts was assessed by determining the total phenolic content, radical-scavenging activity against DPPH●, ABTS+, and NO●, as well as chelating activity towards Cu²⁺ and Fe²⁺.
Results. It was found that among the extracts of polypore fungi fruiting bodies and their fractions, the level of radical-scavenging and chelating activity correlated with the total phenolic content. Among the studied fungi, the extracts of F. fomentarius and Ph. igniarius exhibited the highest antioxidant activity, surpassing the effect of chaga extract. Among the fractions, ethyl acetate extracts were the most effective.
Conclusion. The obtained results reveal new accessible natural raw material sources for the production of highly effective mushroom-derived antioxidants. The extracts of F. fomentarius and Ph. igniarius are of particular interest for further pharmaceutical development.
