Краткое описание

In this research, the chemical composition and anticancer and antioxidant activity of the new medicinal mushroom Ganoderma tsugae var. jannieae CBS-120304 were evaluated. The chemical composition assay includes amounts of total carbohydrates and proteins, amino acids, fatty acids, micro- and macroelements, and vitamins. The investigated medicinal mushroom seemed to be a rich source of nutritional components. Mycelium accumulated more than 2-fold more total protein compared with the fruiting body and reached 37% and 16% of dry weight, respectively. Carbohydrate content in the fruiting body seemed to be conspicuously higher than in the mycelium (50% of dry weight) and reached 80% of dry weight. Quantification of the identified fatty acids indicated that, in general, palmitic acid, oleic acid, and linoleic acid were the major fatty acids. Toxic elements, such as silver, arsenic, cadmium, and mercury, were found only in trace amounts in mycelium and were not detected in the fruiting body. Furthermore, the 1,1-diphenyl-2-picrylhydrazyl free radical scavenging assay was used to evaluate antioxidant activity. The highest radical scavenging activity was 9.0 mg/mL (65.9%) by ethanol extract. In addition, mycelial extracts were tested to inhibit MCF7 breast cancer cells. Ganoderma tsugae var. jannieae ethyl acetate extract (GTEAE) extract showed high potential by inhibiting reporter activity by more than 70%. Results demonstrated that GTEAE had a strong effect on inhibitory protein κΒα level in the higher concentration used (200 gg/mL), which could be compared with the effect of parthenolide. Furthermore, GTEAE demonstrated strong inhibition of IκΒα phosphorylation.
