|Opis:||The main purpose of this thesis was to obtain and analyze the biologically active compounds from the extracts of different types of Polyporaceae family mushrooms. We focused on several different types of mushrooms gathered at various locations across Slovenia, on various types of fruiting bodies and different altitudes. We compared the influence of certain types of habitat on the efficiency of extraction and fatty acid content. We tried to explore the efficiency of conventional extraction with hexane, followed by the characterization of the extracts according to the type of FA by gas chromatography. We performed 31 conventional extraction on different mushrooms from the aforementioned family. Out of these 31, we analyzed 10 of the species most commonly found in Slovenia, which were showing various healing effects. We determined the total phenolic content and antioxidant activity using the DPPH• method, where we researched the amount of biologically active substances (phenols, polysaccharides and proteins).
The preparations made from various medicinal mushrooms (syrups, capsules, teas, oil extracts) help battle viruses and bacteria, improve digestion, help with allergies and overcoming stress and are very effective in the treatment of infections, influenza, diabetes, heart disease. Due to their antioxidant activities and the high levels of polysaccharides, triterpenes and other active ingredients, many mushrooms help in the fight against cancer; they also help remove toxins, strengthen the immune system and detoxify the body, regulate cholesterol levels, lower blood pressure and levels of lipids and improve the general well-being. We concluded that the extracts were rich in FA, phenols and other compounds that are excellent free radical scavengers. The results show a very low percentage of the DPPH• free radical inhibition. Consequently, we can claim that the FA do not have as many antioxidative properties as some phenolic compounds.|
