        The objective of this study was to determine the anti-diabetic effect of the water extract of Neolentinus lepideus in a diabetic mouse model. Seven-week-old C57BL/KsJ-db/db mice were fed either a control diet (CD) or diet supplemented with 1% or 5% of N. lepideus water extract (NLWE1 or NLWE5) for 10 weeks. Oral administration of NLWE significantly decreased the body weight gain compared to that of CD-fed group. Mice in the NLWE group had significantly lower levels of fasting serum glucose, fatty acids, and low-density lipoprotein cholesterol compared to those in the control group. These effects were accompanied by reduced fatty liver and improved glucose tolerance in the NLWE group. Taken together, these results suggest that N. lepideus might have potential as a dietary supplement to control diabetes.

        The purpose of this study is to investigate the physiological activities of the water and ethanol extracts from three strains of Hypsizygus marmoreus. Anti-oxidant and anti-tumorigenic activities were carried out. As the anti-oxidant test ORAC(Oxygen Radical Absorbance Capacity) assay was performed. Nitrite scavenging activity and MTT assay were conducted to confirm the anti-tumorigenic activities. HeLa and A549, MCF-7 cell lines were used for MTT assay. GONJI No.6 ethanol extract showed highly effects on anti-tumorigenic activities among three strains. But water extracts were not shown anti-tumorigenic activities. As a result of the anti-oxidant activity the Hypsizygus marmoreus(from Japan) water extract showed highest radical absorption activities on ORAC assay.

        This study was conducted to investigate the physiological activities of the water and ethanol extracts from three strains of Hypsizygus marmoreus. Largely, anti-hypertensive, anti-inflammatory, anti-diabetic, anti-tumorigenic activities were carried out. In addition, β-glucan contents were also measured. Mangadak 2 ho has the 36%(w/w) β-glucan contents, it is highest value of all strains. And it also showed highest inhibitory activities of angiotensin converting enzyme. GONJI No.6 highly inhibited releasing of nitric oxide from Raw 264.7. Anti-diabetic activity, the Hypsizygus marmoreus(from Japan) showed highest inhibitory activity on amyloglucosidase. MTT assay was performed on the anti-tumorigenic test. The cancer cell were used to HeLa, A549. repectively.

        This study was conducted to investigate the physiological activities of the water and methanol extracts from Auricularia auricula-judae(black and brown) and Auricularia polytricha. Largely, anti-oxidant, anti-tumorigenic, anti-inflammatory, anti-diabetic activities were carried out. DPPH scavenging activity was performed on the anti-oxidant test. MTT assay and nitrite scavenging acitivity were performed on the anti-tumorigenic test. The cancer cell were used to HeLa, A549, HT-29 and MCF-7 and normal cell was used as control. lastly, in the anti-inflammatory and anti-diabetic activities, NO assay and α-amyloglucosidase inhibition were performed, repectively.

        This purpose of this study was to analyze the nutritional composition about Auricularia spp., which has been used to Auricularia auricula-judae(black and brown) and Auricularia polytricha. First, the contents of total polyphenol and beta-glucan were analyzed. Subsequently, the contents of free sugars, amino acids and organic acids were analyzed by HPLC. In addition, the content of vitamin D from these strains was also measured and the D3 of this vitamin D was anlyzed. In conclusion, Auricularia spp. showed evident differences in the nutritional composition.

        This study was conducted to investigate the physiological activities of the ethanol extracts from 3 different strains of Hericium erinaceum. In addition, the β-glucan and polyphenol contents from these strains were also measured. As a result, total polyphenol contents were the highest in 1ho(39.07 mg%) strain and lowest in 2ho(17.59 mg%). β-glucan contents ranged from 17.69 to 18.26%. In the physiological activities, Inhibition effects of DPPH radical and Nitrite ranged from 3.29 to 9.6% and 1.52 to 5.27%, respectively. Inhibitory effects of nitric oxide production ranged from 23.72 to 33.47%. The highest inhibitory activities on α-amyloglucosidase activity and angiotensin I converting enzyme were 39.30% and 14.10%, respectively. Lastly, the cytotoxic activities of ethanol extracts from all the strains on A549, HT-29 and HeLa cell was shown the highest effect in A549 cell.

        In this study, the anti-oxidant, anti-tumorigenic, anti-hypertensive, anti-thrombic, anti-diabetic, and anti- inflammatory properties of 18 different species of genus Pleurotus were investigated. In addition, the amino acid, β-glucan, and polyphenol contents were also measured. The β-glucan and polyphenol contents were the highest in Pleurotus cornucopiae var. citrinopileatus (yellow Pleurotus) of all species. The yellow Pleurotus also exhibited the highest physiological activity as assessed by the DPPH IC, Cytotoxic activity, ACE activity and so on. To confirm the mechanism for the physiological activity of the yellow Pleurotus, we performed further examinations within ICR mice. The yellow Pleurotus reduced glucose, triglyceride and total cholesterol levels in the ICR mice blood for 4 weeks after feeding, and also significantly lowered both GOT and GPT levels. Taken together, our data indicates the yellow pleurotus is a promising functional food ingredient.
