The invention relates to a Grifola frondosa polysaccharide ZZK component and a preparation method thereof. The fruit body in Grifola frondosa is used as the raw material and is subjected to drying, crushing, extraction, purification and other processes, thus being separated into a beta glucomannan (ZZK). The beta glucomannan (ZZK) comprises the main monosaccharides of glucose and mannitose, has a weight-average molecular weight of 380-750 thousand Daltons and has remarkable antineoplastic activity. |
