ABSTRACT

The inflammatory response caused by the immune system can be defensive, but a long-term inflammatory response may lead to the development of many different chronic diseases. In this study, 4 extracts were prepared from Hypsizygus marmoreus and Pleurotus eryngii fruiting bodies and used to evaluate their effects on inflammation-related mediators in RAW 264.7 cells. The 4 extracts contained substantial amounts of phenolic compounds (5.10-9.96 mg/g extract) and flavonoids (1.92-5.13 mg/g extract). With the extracts added, the production of nitric oxide and the proinflammatory interleukin (IL)-6 could be effectively suppressed, whereas the production of the proinflammatory tumor necrosis factor-α and IL-1Β could be relatively suppressed. In addition, production of the anti-inflammatory cytokine IL-10 could be increased. Overall, these mushrooms might be capable of amending inflammatory responses.
