Popis: The extraction of bioactives from Pleurotus eryngii was addressed using innovative extraction techniques. Microwave hydrodiffusion and gravity, which yielded less than 1% of the initial material, can be proposed as an initial stage to dehydrate the mushroom. Autohydrolysis or hydrothermal extraction using water under subcritical conditions allowed solubilization of up to 80% of the dry weight of the mushroom and produced an extract rich in monosaccharides and oligosaccharides, which also contained 2 g gallic acid equivalents (GAE)/100 g extract and showed antiradical capacity equivalent to 30 mg Trolox/g extract. Supercritical carbon dioxide is an alternative solvent with ability to selectively extract lipophilic fractions (
