Szukana fraza: [Abstrakt = "he pink oyster mushroom – a popular arboreal edible mushroom, as it showed a profile of indole and phenolic compounds composition similar to that of Fomitopsis officinalis. Results During the first stage of the project, in vitro cultivation of Fomitopsis officinalis was optimized in the conditions of the Department of Pharmaceutical Botany, Faculty of Pharmacy, Jagiellonian University Medical College mushroom laboratory\; and, the species identity of the obtained material was confirmed. Subsequently, it was shown that\: 1\) a precursor for serotonin \(5–hydroxy–L–tryptophan\), a precursor for dopamine \(phenylalanine\), and a flavonoid with antioxidant properties \(catechin\) are present in Fomitopsis officinalis grown in vitro, but not in the fruiting bodies of Fomitopsis officinalis of natural origin\; 2\) Fomitopsis officinalis from in vitro cultures contains\: 2 times more provitamin D2 \(ergosterol\) and zinc, 3 times more iron and slightly more magnesium than the fruiting bodies of Fomitopsis officinalis of natural origin\; 3\) fortification of Fomitopsis officinalis with zinc or magnesium sulphates has a positive effect on the bioavailability of 5–hydroxy–L–tryptophan, while fortification with magnesium – on the bioavailability of phenylalanine\; 4\) digestion of the fruiting bodies leads to a \~2.5–fold decrease in their antioxidant activity, while the activity"]
