Sažetak
Russula cyanoxantha is one of the most common species of Russula in Europe. It is edible and delicious mushroom. Mushrooms are currently valued for biologically active substances as they contain many valuable compounds such as fatty acids, amino acids, proteins, carbohydrates, trace elements etc. Considering the growing interest for mushrooms, objectivity of this study was to investigate extracts from R. cyanoxantha. Two different extracts were prepared. Extraction yield of extract obtained using 50% ethanol was 37.67%. In this extract content of total phenolic compounds was determined as 26.66 mg GAE/g of extract. Antioxidant activity o this cyanoxantha ethanolic extract reach IC50 value at the extract concentration of 0.062 mg/ml. Also it was confirmed the extract is capable of reduction iron (III) and thus, is capable of donating electrons. Extraction yield of extracts obtained by supercritical carbon dioxide was 2.06%. High pressure carbon dioxide fluid extraction has been documented as an effective method for preparing bioactive products from plant materials. Asfatty acids are on of valuable mushrooms compounds the extract fatty acid profile was determined by GC/MS and GC/FID analysis. Most dominant fatty acid was essential linoleic with content of 41.61%.
