AB  - Chaga (Inonotus obliquus) is a parasitic fungus, which has been used in traditional medicine in Russia and other northern European countries in the treatment of cancer, gastrointestinal andliver diseases. It has been a subject of intensive researchrecently, confirming many of its health-beneficial effects. In order to obtain a product that would allow modified and prolonged release of the Chaga's active metabolites, hot water Chaga extract was immobilized using calcium - alginate. The extract, which was predominantly composed of carbohydrates (57 %), also contained a relatively high amount of antioxidants/phenolic compounds (130 mg gallic acid equivalents per g of dry extract) and exhibited pronounced radical scavenging activity. It showed significant antibacterial activity as well, inhibiting growth of tested bacterial strains at concentrations of 1.25-20 mg/mL. Entrapment efficiency was about 80 %, and the extract-alginate system showed pH-dependant extract release; there was negligible release at pH 1.75 (gastric pH), and the release gradually increased with the increase in pH, reaching similar to 43 % of immobilized extract at pH 8.5 after 90 min. Such a product could be used as a dietary supplement, adjuvant in therapy of gastrointestinal diseases or as a food additive.

AB  - Puffballs are fungi that produce globose fruiting bodies that undergo autolysis, transforming their insides into a spore bearing, powdery mass. Mature fruiting bodies are traditionally used to treat open skin wounds. In this study, methanol extracts of two puffball species, Handkea excipuliformis and Vascellum pratense, were examined and compared in order to provide insight into the changes these mushrooms undergo during maturation, with respect to their potential use in skin care and wound treatment. Some compounds involved in skin care and regeneration were quantified, and it was found that maturation increases the concentrations of almost all of these compounds. Antioxidant activity was also more pronounced in mature fruiting body extracts, which was in correlation with the higher content of antioxidants. Tyrosinase inhibition was vastly improved with autolysis, correlating with the higher phenolic content in mature fruiting body extracts. Antimicrobial activity was negatively affected by autolysis in the case of H. excipuliformis, whereas autolysis had little effect on the antimicrobial activity of V. pratense. Autolysis generally improved the biological activity and increased the concentrations of compounds involved in skin care, which justifies the traditional use of puffballs and makes them good candidates for various potential cosmetic and medicinal skin-care products.
