Fig. 1. Fruiting bodies of the wild mushrooms in this study (A, OK795; B, OK804; C, OK811; D, OK825; E, OK826; F, OK829; G, OK832; H, OK904; I, OK943; J, OK944).
Fig. 2. DPPH radical scavenging activities of wild mushroom extracts (1mg/ml concentrations). White bar indicates a positive control. The results are represented by the mean ± S.D. of values obtained from three replications (OK795, Amanita manginiana; OK804, Suillus granulatus; OK811, Leucopaxillus giganteus; OK825, Clitocybe robusta; OK826, Hypholoma fasciculare; OK829, L. giganteus; OK832, Leucopaxillus sp.; OK904, Lactarius chrysorrheus; OK943, Pholiota limonella; OK944, A. manginiana). Different letters are significantly different by Duncan’s multiple range test (p<0.05).
Fig. 3. Nitrite scavenging activities of wild mushroom extracts (1mg/ml concentrations). White bar indicates a positive control. The results are represented by the mean ± S.D. of values obtained from three replications (OK795, Amanita manginiana; OK804, Suillus granulatus; OK811, Leucopaxillus giganteus; OK825, Clitocybe robusta; OK826, Hypholoma fasciculare; OK829, L. giganteus; OK832, Leucopaxillus sp.; OK904, Lactarius chrysorrheus; OK943, Pholiota limonella; OK944, A. manginiana). Different letters are significantly different by Duncan’s multiple range test (p<0.05).
Fig. 4. Total polyphenol contents of wild mushroom extracts (1mg/ml concentrations). White bar indicates a negative control. The results are represented by the mean ± S.D. of values obtained from three replications (OK795, Amanita manginiana; OK804, Suillus granulatus; OK811, Leucopaxillus giganteus; OK825, Clitocybe robusta; OK826, Hypholoma fasciculare; OK829, L. giganteus; OK832, Leucopaxillus sp.; OK904, Lactarius chrysorrheus; OK943, Pholiota limonella; OK944, A. manginiana). Different letters are significantly different by Duncan’s multiple range test (p<0.05).
Fig. 5. The suppression rates of nitric oxide (NO) by the treatment of wild mushrooms extracts were determined by using NO assay. RAW 264.7 cells were incubated under 1 μg/ml concentration of lipopolysaccharide (LPS) and wild mushrooms extracts. White bars indicate positive and negative controls. The results are represented by the mean ± S.D. of values obtained from three replications (OK795, Amanita manginiana; OK804, Suillus granulatus; OK811, Leucopaxillus giganteus; OK825, Clitocybe robusta; OK826, Hypholoma fasciculare; OK829, L. giganteus; OK832, Leucopaxillus sp.; OK904, Lactarius chrysorrheus; OK943, Pholiota limonella; OK944, A. manginiana). Different letters are significantly different by Duncan’s multiple range test (p<0.05).
Fig. 6. The rates of cell viability after treating wild mushrooms extracts. Viability of RAW 264.7 cells harvest at 24 hr after 1 μg/ml concentration of LPS addition was determined using MTT assay. White bars indicate positive and negative controls. The results are represented by the mean ± S.D. of values obtained from three replications (OK795, Amanita manginiana; OK804, Suillus granulatus; OK811, Leucopaxillus giganteus; OK825, Clitocybe robusta; OK826, Hypholoma fasciculare; OK829, L. giganteus; OK832, Leucopaxillus sp.; OK904, Lactarius chrysorrheus; OK943, Pholiota limonella; OK944, A. manginiana). Different letters are significantly different by Duncan’s multiple range test (p<0.05).
