Various studies on the effect of mushroom, a member of phytonutrients, on inflammatory diseases have been reporter over the years, Among various species mushrooms, King oyster mushroom (Pleurotus eryngii) and winter mushroom (Flammulina velutipes) are popular dietary ingredients for Asian cuisine. The extracts from all the three mushrooms were used to determine the antioxidative effect and the cytotoxicity. Result analysis were repeated more than three times to get an average${\pm}$standard deviation, and statistical significance were confirmed by SPSS. As a result, total phenol content of the king oyster mushroom and the winter mushroom were $19.66{\pm}0.10mg/g$ and $22.08{\pm}1.10mg/g$, respectively. Also, the total flavonoid content was $15.21{\pm}1.31mg/g$ for the king oyster mushroom and $20.50{\pm}4.52mg/g$ for winter mushroom. The results in winter mushroom showed higher values in total phenol and flavonoid content than in the king oyster mushroom. All samples of extracts showed free radical DPPH (1,1-diphenyl-2-picrylhydrazyl) scavenging activity with their 10 mg/mL concentration. These results indicate that the extract of the king oyster mushroom (Pleurotus eryngii) and the winter mushroom (Flammulina velutipes) may be possible phytonutrients with the anti-inflammatory and the anti-cancer effect.

Mushroom is very important to rural dwellers due to the various economic, health and nutritional benefits that can be derived from its consumption, sales and utilization. Hence, this experiment was carried out with a view to evaluating the influence of locally available substrate i.e., sawdust of different wood species on the cultivation of Pleurotus ostreatus (oyster mushroom). Pleurotus ostreatus was grown on sawdust (indigenous and exotic species) using two pretreatment methods, which included hot water treatment to remove (a water-soluble extract) and non-extracted sawdusts (substrate). The result of this study showed that there was a significant difference in the effect of different wood species selected. Parkia biglobosa produced a better yield (71.06 g), followed by Anogeissus leiocarpus (53.17 g) and Gmelina arborea (51.39 g) in a non-treated unextracted states. In the treated samples, Parkia biglobosa has the highest yield (50.61 g) followed by Anogeissus leiocarpus (49.28 g) and Gmelina arborea (45.00 g). Thus, Parkia biglobosa and Anogeissus leiocarpus produced a higher yield of mushroom either in a treated or non-treated state and they could be recommended for growing oyster mushroom (Pleurotus ostreatus).

Body fat-reducing ability of oyster mushroom (Pleurotus ostreatus) water extract (OMWE) was investigated of mice by supplying it drinking water. OMWE(2.95% solid content ) was prepared by extracting a low grade of the mushroom at 12$0^{\circ}C$ for 10min. The solid material of OMWE was composed of 65.2% reducing sugar, 0.23% crude fat, 0.5%total protein, 1.2% ash and 32.9% others. OMWE was appropriately diluted with drinking water. Seventy two male ICR mice(25$\pm$1 g, 7~8 weeks of age, 6 mice/cage, 18 mice/treatment) housed in polycarbonate cages containing $\beta$-chips were adopted in a temperature-and humidity-controlled facility with free access to water and diet. One week later, the mice were subjected to one of the treatments for 36days : 0 (control), 10, 50 and 100% OMWE. Drinking wter with or without OMWE was supplied twice (40ml each, 80ml in total ) daily per cage. Body weight and fed intake were recorded every three days. At the end of the experiment, mice were sacrificed to determine the chemical composition (fat, protein, ash and water). Body weight of mice treated with OMWE (10, 50 and 100%) at day 36 was 35.9, 35.9and 35.5g per mouse , respectively, and not significantly reduced as compared to that (36.5g/mouse) of control mice. Average body fat of 0,10,50 and 10% OMWE -treated mice was 14.3, 13.1, 10.7 and 12.0% , respectively. Body fat reduction by 50% OMWE treatment was 25.2% (p<0.05) relative to control. OMWE did not affect feed intake. The contents of body protein and ash were increased with respect to body fat decrease, while water content was not changed much. These results suggest that OMWE could reduce body fat of the mice without body weight change, giving the best effect by 50% OMWE.

느타리버섯은 한국사람들에게 인기있는 버섯이며 새송이버섯, 팽이버섯과 더불어 대부분 많이 재배되어지는 버섯이다. 느타리버섯의 항산화 효능과 폴리페놀 함량을 비교 분석하였다. 항산화 효능을 분석한 결과 열수추출에서는 ASI 2099가 가장 높게 나타났으며, 주정과 메탄올 추출물에서는 ASI 2122가 가장 높게 나타났다. 폴리페놀 성분은 대부분 7~10 mg/g 이었으며, 추출용매별 함량차이는 크지 않았다.

Objective: The aim of this study was to investigate antioxidant activities of cinnamon (Cinnamomum cassia) extracts (extracted with different solvents) at various concentrations and to determine product quality of raw chicken patties added with different levels of cinnamon powder (CP) and oyster mushroon powder (OMP) during storage. Methods: After cinnamon was made into oven dried CP and extracted with water and different levels (50%, 80%, and 100%) of ethanol, antioxidant activities of these extracts were determined. CP and OMP were combined at different levels and added to raw chicken patties. Physicochemical properties and microbial counts were measured during refrigerated storage. Results: Cinnamon ethanol (80%) extract showed the highest (p<0.05) by 2,2-diphenyl-1picrylhydrazyl-radical scavenging activity and reducing power. Cinnamon water extract (CWE) had the highest iron chelating ability (p<0.05), while CP 100% ethanol extract had the highest content of total phenolic compound. Then, CP and OMP were applied to chicken patties at different levels (0.1% to 0.2%). After the addition of CPs, pH, L* (lightness), 2-thiobarbituric acid reactive substance, and volatile basic nitrogen values were decreased, whereas a* (redness) and b* (yellowness) values were increased. Microbial counts of total bacteria and Enterobacteriaceace were decreased with the addition of CP 0.2% regardless of the OMP level. Conclusion: The addition of CP in combination with OMP can increase the shelf-life of chicken patties during storage.
