Oyster mushroom is one of the popular mushrooms for Korean people and it is thus one of the mushrooms that were mostly cultivated in Korea in addition to winter and king oyster mushrooms. This study was carried out to compare the medicinal effects of fruiting body of Pleurotus ostreatus extracts, winter extracts, king oyster extracts. We analyzed comparing antioxidant activity , nitrite scavenging activity, anti-inflammatory efficacy and inhibiting cancer cell growth. Antioxidant activity of king oyster and Pleurotus ostreatus mushrooms through the analysis of DPPH showed to be short of 10%, but ASI 4149, F4 in winter mushrooms showed the highest level 20-30%. Nitrite scavenging activity of Pleurotus ostreatus mushrooms were also seen as a high efficacy effects in 30-40% similar to the positive control. also, No. 1, F6, F1 in winter mushrooms showed the highest level 30% to 40% and king oyster is about 20%.
Anti-inflammatory efficacy of ethanol extracts of ASI 2084 and methanol extracts of ASI 2003 in Pleurotus ostreatus mushrooms showed 31.0%, respectively. ASI 4065, 4074 in winter mushrooms showed are 20.2% and 13.6% respectively. king oyster showed an efficacy of less than 20%. Inhibiting lung cancer cell growth of oyster mushroom is less than 10%, Among that the ASI 2100 was the highest with 12.8%. seolseong, F9 of in winter mushroom showed highest levels 30% for Inhibiting stomach cancer cell growth. ASI 2887 in king oyster mushroom showed that 23% for Inhibiting stomach cancer cells growth
Physiological activities of 70% methanol, fermented ethanol and hot-water extracts of Pleurotus eryngii were investigated. Free radical scavenging activities of P. eryngii extracts were determined according to the elimination of DPPH radicals. Their nitrite scavenging activity and total polyphenol content were also determined. Amino acid analysis showed that phenylalanine (Phe) and glutamic acid (Glu) are most abundant essential and non-essential amino acids in the analyzed extracts. The hot-water extract of ASI 2394 represented the highest antioxidant activity with the DPPH radical scavenging rate value of 40.97±1.65%. ASI 2820 displayed the superior capacity to eliminate nitrate regardless of extraction solvents. The hot-water extract of ASI 2887 had the highest content of polyphenol. Our results showed that P. eryngii is well qualified as a functional food.
