BIOLOGICAL ACTIVITY OF EXTRACTS FROM THE MYCELIUM OF MEDICINAL MUSHROOM INONOTUS RHEADES
Journal Title: International journal of ecosystems and ecology science (IJEES) - Year 2018, Vol 8, Issue 3
Abstract
The search for bioactive natural compounds potentially having antitumor activity - important problem of modern science. We have previously demonstrated high in vitro antiradical activity of water ethanol extracts (WEE) from the mycelium of Inonotus rheades. In the present study we evaluated the effect of 30% and 70% of WEE from mycelium I. rheades on the cell culture of human tumor cells HEp-2. 50% cell death is achieved after 24-h incubation in 53 µg/ml 70% WEE (dry weight), whereas 30% WEE at 550 µg/ml only, i.e. an order of magnitude difference between the concentrations, which indicates that high cytotoxic activity was shown WEE a radical change in the qualitative composition of extractives with increasing ethanol concentration. Incubation of cells with 250 mM H2O2 resulted in approximately 40% cell death, whereas pre-incubation with both 30% and 70% of WEE resulted in 100% survival of cells in a large range of concentrations. This indicates a WEE protective effect under oxidative stress. Thus, WEE of the mycelium I. rheades in high concentrations exhibit cytotoxic activity. At the same time, a wide range of concentrations extracts can neutralize the oxidative stress and cell death caused by the addition of H2O2.
