  • Publication number: 20210130767
    Abstract: The invention relates to a rare edible fungus new strain and an artificial cultivation method and use thereof, in particular to a new species Pholiota glutinosior of genus Pholota and its artificial cultivation method and use. The new strain of genus Pholiota of the present invention is collected from the Guangdong Chebaling National Nature Reserve, and is identified as a new strain of genus Pholiota, and the original strain is obtained by tissue separation, and is named as HMGIM-W140054, deposited on Jun. 3, 2019, at China Center for Type Culture Collection (CCTCC, Wuhan, China), with the accession number CCTCC NO: M 2019414. The new strain of the invention has been artificially domesticated and cultivated, exhibits a strong and significant inhibition rate against Staphylococcus, and has a high content of histidine, crude polysaccharide and potassium. It is rich in nutrients and has high cultivation yield, and is a new species with high development prospects.

  • Patent number: 10155822
    Abstract: A Grifola frondosa polysaccharide F2 with hypoglycemic activity, process for preparation and use thereof. The process for preparation of Grifola frondosa polysaccharide F2 is as follows: The fruit bodies of Grifola frondosa were homogenized to a fine powder and extracted with hot water. The mixture was filtered and precipitated with absolute ethanol. The precipitation was obtained. The said precipitation was applied on DEAE Sepharose Fast chromatographic column, equilibrated with Tris-HCl (10 mM, pH=8.0), collecting the efficient eluting peak to obtain the fraction F1; eluted with Tris-HCl (10 mM, pH=8.0) which contains 0.1M NaCl, fraction F2 was obtained; then concentrated under reduced pressure, dialyzed and lyophilized, Grifola frondosa polysaccharide F2 was obtained. This isolates a new Grifola frondosa polysaccharide F2 with hypoglycemic activity from the fruit bodies of Grifola frondosa. The Grifola frondosa polysaccharide F2 can be used in manufacturing a drug for treating diabetes.

  • Publication number: 20110244556
    Abstract: The present invention relates to a method for preparing Ganoderma spore oil which is in the field of biotechnology. The method includes using Ganoderma spore powder and Ganoderma powder (obtained from grinding fruiting bodies) as raw materials, applying enzymatic Ganoderma sporoderm broken methods, one-step granulation, supercritical CO2 extraction method, as well as centrifugation and refining. The light yellow oleaginous substances obtained posses a variety of physiological functions such as strengthening immunity, protecting the liver and inhibiting tumor cell growth, etc. Ganoderma spore oil prepared with the present technology contains not only spore extracts, but also extracts from Ganoderma fruiting bodies and mycelium by CO2 supercritical extraction, with more types of triterpenoids. The inhibitory effects of Ganoderma spore oil is a onefold higher than spore oil prepared from the physical preparation of the sporoderm-broken spore.

  • Patent number: 7614989
    Abstract: An exercise machine includes a bench and board section including a stationary bench having first and second opposite ends, and a board having first and second opposite ends, with the first end of the board pivotally mounted adjacent the second end of the stationary bench, each of the bench and board being formed substantially from a single piece which can selectively support a torso of a person and legs of the person, and a resistance device in contact with the single piece board and which applies a resistance to pivotal movement of the board, while permitting the board to swing up and down against a resistance applied by the resistance device.
