  • Patent number: 8206760
    Abstract: Disclosed is a composition for the inhibition of transplant rejection and the treatment of skin diseases, comprising a cordyceps mycellia extract as an active ingredient. The cordyceps mycellia extract significantly suppresses the production of antibodies to transplants without side effects, such as weight change. Based on natural material, the composition is non-toxic and harmless to the human body and thus can be used as an immunosuppressant for organ transplantation. Also, it stops oozing from sores and is useful in the treatment of skin diseases, including atopy, allergic reactions, decubitus ulcers, pemphigus and smallpox.

  • Patent number: 6943007
    Abstract: There is disclosed novel Phellinus linteus Yoo. This mushroom is identified as novel as analyzed by restriction fragment length polymorphism and by microbiological features. A polysaccharide substance isolated from the fruiting bodies or mycelia the strain and other Phellinus spp. has an anticancer activity by inciting the cytotoxicity of T-cells and the antibody forming potency of B-cells. Also, the polysaccharide substance shows a potent activity against cancer metastasis. The polysaccharide substance, which can stimulate the immunity of the body, may be effective in the prophylaxis and treatment of immune-related diseases, such as cancers and AIDS, and in the study on the basic mechanism of the diseases.

  • Patent number: 6066748
    Abstract: The present invention teaches a method of extracting TAXOL.RTM. from the leaves of taxus cupidata plants. The process comprises a series of steps, including the concentration of the extracts obtained from the plant, the separation of the aqueous and chloroform phases, and several purification procedures. In addition, the present invention teaches a multi-step process wherein the virtual removal of chlorophyll is achieved prior to the introduction of the extract into the silica gel packing material. This prevents the deactivation of the silica gel packing material by chlorophyll in the extract solution.
