Abstract: This invention pertains to the field of plant extraction and separation technology, and provides a polysaccharide compound with a defined molecular structure that possesses antitumor efficacy. The polysaccharide compound is intended for the treatment of advanced cancer patients (those who are no longer candidates for surgery, have a life expectancy of only three to six months, and are still eligible for chemotherapy). The molecular formula is: (C30H50O25)n. The active ingredient, polysaccharide, is obtained through the extraction of effective components from Ganoderma lucidum under high temperature and high pressure. The polysaccharide with this active ingredient, characterized by its water solubility, is readily absorbed by the human body, offers antitumor effects, and has proven efficacy in the prevention of tumor development in humans.

Abstract: This invention pertains to the field of plant extraction and separation technology and provides a polysaccharide compound with a well-defined molecular structure. The polysaccharide compound is suitable for treating patients with advanced cancer (where surgical options are no longer viable, life expectancy is only three to six months, and chemotherapy remains feasible), including the following steps of: S1. dust removal, drying, and crushing of Ganoderma lucidum; S2. mixing with water in a sealed container and extracting an active ingredient under high temperature and high pressure; S3. removing the residues from the concentrated extract containing the active ingredient; and S4. formulating the residue-free concentrate to a specific concentration and isolating polysaccharide with the active ingredient by column chromatography. The polysaccharide with this active ingredient, characterized by its water solubility, is readily absorbed by the human body.

Abstract: This invention pertains to the field of plant extraction and separation technology, and provides a polysaccharide compound with a defined molecular structure that possesses antitumor efficacy and mitigates the toxic side effects of chemotherapy. The polysaccharide compound is intended for the treatment of advanced cancer patients (those who are no longer candidates for surgery, have a life expectancy of only three to six months, and are still eligible for chemotherapy). The molecular formula of the polysaccharide compound is: (C66H110O55)n. The active ingredient, polysaccharide, is obtained through the extraction of effective components from Ganoderma lucidum under high temperature and high pressure. The polysaccharide with this active ingredient, characterized by its water solubility, is readily absorbed by the human body, offers antitumor effects, and has proven efficacy in the prevention of tumor development in humans.

Abstract: This invention pertains to the field of plant extraction and separation technology and provides a polysaccharide compound, GLP-4, with a defined molecular structure, effective in treating emphysema and pulmonary fibrosis, and exhibiting antitumor effects. The molecular formula is: (C162H270O135)n. The polysaccharide compound is obtained by extracting from a residue of Ganoderma lucidum processed with alkaline solution under high temperature and high pressure, followed by column chromatographic separation. The polysaccharide compound features excellent water solubility and is readily absorbed by the human body. The polysaccharide compound shows superior efficacy in treating emphysema and pulmonary fibrosis compared to pirfenidone and is also effective for patients with advanced cancer (those who are no longer surgical candidates, with a life expectancy of only three to six months, and still eligible for chemotherapy).
