Endogenous cytokinins in mycelia of medicinal mushrooms Hericium coralloides and Fomitopsis officinalis grown in vitro were identified using high-performance liquid chromatography coupled with mass spectrometry. High amounts of zeatin-type cytokinins and isopentenyladenine were found. The qualitative composition and quantitative content of cytokinins were species-specific traits of mushrooms.

The article presents the results of the investigation of the effect of biomass powder of the fungus Ganoderma lucidum on T-cell-mediated immunity in normal and immunosuppressed mice CBA/Ca. Delayed-type hypersensitivity assay was used. Experimental immunodeficiency was established with intraperitoneal injection of the immunosuppressant cyclophosphamide at a single dose of 150 mg/kg on the first day of the experiment.

The content of proteins, lipids, and amino and fatty acids was investigated in mycelium and culture broth of medicinal mushrooms Cordyceps sinensis, Pleurotus ostreatus, and Schizophyllum commune. Seven essential amino acids were present in the proteins of all mushroom samples, with aspartic (6.34%-14.
