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: (CHO). The active ingredient, polysaccharide, is obtained through the extraction of effective components fromunder 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.
