The invention discloses hirudo polypeptide with functions of antithrombus and brain nerve cell protection and application of the hirudo polypeptide, and relates to the fields of traditional Chinese medicine, natural medicine and health care products. The structure of the hirudo polypeptide is presented as a formula I, human umbilical vein endothelial cell expressing vascular hemophilia factor (vWF) and a plasminogen activator inhibitor-1(PAI-1) can be significantly lowered at the low concentration of the hirudo polypeptide, the survival rate of nerve cells after oxygen and glucose deprivationis increased, platelet aggregation in vitro is inhibited, the plasma recalcification time is prolonged, formation of thrombi in vivo is reduced, neurobehavior after cerebral infarction of a rat is improved, encephaledema is relieved, the area of cerebral infarction is reduced, the toxicity is low, good application prospects are achieved, and the hirudo polypeptide can be used for preparing medicine or health care products for treating or adjuvant therapy of cardiovascular and cerebrovascular diseases such as atherosclerosis, thrombi and cerebral post-stroke nerve function deficit. The formulaI is NH2-Leu-D-Leu-Ser-Gly-Val-R whitmantide A: R=D-Leu-Gly-COOHwhitmantide B: R=D-Leu-Gly-Gly-COOH whitmantide C: R=COOH.

The invention discloses a perinereis aibuhitensis anticoagulation peptide and use thereof. The amino acid sequence of the perinereis aibuhitensis anticoagulation peptide is Pro-Val-Glu-Arg-Lys. The perinereis aibuhitensis anticoagulation peptide is high in anticoagulation activity, has an antithrombus effect, and has a preferable medical application value.

The invention discloses high-purity mannan. The high-purity mannan is produced by beta-mannase controllable enzymolysis of konjak refined powder and is purified to obtain a polysaccharide system of which the weight average molecular weight is 20000-25000Da. After the polysaccharide system is applied to a product for reducing blood glucose, the blood glucose can be obviously reduced by eating the product; and after the polysaccharide system is subjected to derivatization treatment, the polysaccharide system has anti-coagulation and anti-thrombus effects and is an important heparitin raw material.
