Abstract: Russula mushroom is mostly found in Northeastern part of Thailand. It has been used as foods and for the treatments of various diseases for a long time. However, less information of the anti-inflammatory activity of R. mushroom is revealed. The aim of this study was to evaluate the phytochemical constituents the anti-inflammatory mediator effect of Russula mushroom extracts including R. alboareolata (Nam-Pang in Thai), R. medullata (Ko-Kab-Yang in Thai), R. virescens (Khai-Domg in Thai) and R. helios (Ko-Reng-Som in Thai) on lipopolysaccharide-induced RAW 264.7 cells. The extract was prepared by maceration of dried mushrooms with 95% ethanol. Phytochemical components of extracts were analyzed by high performance liquid chromatography (HPLC) technique. It was found that all extracts possessed similar specific chromatographic fingerprints that exhibited peaks which corresponded to oleanolic acid. Results of water-soluble tetrazolium salt (WST-1) assay exhibited IC50 value of R. alboareolata (760.97 ± 28.95 µg/mL), R. medullata (484.44 ± 07.43 µg/mL), R. virescens (907.14 ± 52.37 µg/mL) and R. helios (514.78 ± 14.35 µg/mL) indicating their slight-cytotoxic effect. In inflammatory inhibition, R. alboareolata extract exhibited the highest in nitric oxide inhibition and prostaglandin E2 inhibition on lipopolysaccharide-induced RAW 264.7 cells at 78.80 ± 6.70 % and 66.62 ± 9.53 %, respectively. Including COX-2 inhibition, this extract showed the highest % COX-2 inhibition at 57.41 ± 2.27. These results suggest that the R. alboareolata extract is potential of anti-inflammatory activity on RAW 264.7 without affecting.
