Abstract

Mushrooms are increasingly being studied for the development of new dietary supplements and drugs, which necessitates the analysis of their chemical profiles to assess their nutritional and health benefits. This research focused on the mycelium of edible mushrooms, Laetiporus sulphureus and Flammulina velutipes. The study aimed to enhance the production of health-promoting secondary metabolites using elicitors salicylic acid (SA) and methyl jasmonate (MeJa) and to evaluate the extraction of organic compounds and bioelements with pro-health properties into artificial digestive juices from both the mycelium and sporocarps. The extracts were analyzed using HPLC-DAD for organic compounds and flame atomic absorption spectrometry (FAAS) for bioelements. The results showed that the elicitors increased the synthesis of secondary metabolites, with MeJa at 50 µmol/L being the most effective in F. velutipes. The high extraction of bioelements and selected metabolites into artificial digestive juices suggests good potential bioavailability, indicating that these mushroom materials, with elevated medicinal substances, could be used in health-promoting preparations.
