Zusammenfassung:The invention discloses a muskroot-like semiaquilegia root glycopeptide as well as a preparation method and application thereof, and particularly discloses a galacturonic acid-containing glycopeptide SA02C extracted from muskroot-like semiaquilegia root tuber, a preparation method of the galacturonic acid-containing glycopeptide SA02C, and application of the glycopeptide SA02C in preparation of drugs for preventing and/or treating neurodegenerative diseases, particularly Alzheimer's disease, and particularly for preventing and/or treating the neurodegenerative diseases. The invention also relates to application of the compound in a medicine for inhibiting the generation and/or aggregation of A beta 42. The glycopeptide SA02C is prepared from the following components in percentage by weight: 71 to 75 percent of polysaccharide and 25 to 29 percent of protein; in the polysaccharide, the molar ratio of galacturonic acid to rhamnose to glucose to galactose to xylose to arabinose is (60-72): (4.2-8.2): (2-6): (5-9)
