Problems solved by technology

[0004] However, the chemical composition of trigonium is complex, containing compounds such as flavonoids and flavonoid glycosides, phenylpropanoid glycosides, steroids and their glycosides, organic acids, although modern chemical and pharmacological studies have partially clarified the connection between chemical components and clinical applications , but there are still many active ingredients that have not been found, and many pharmacological studies only stay at the stage of extracts, which limits the further promotion and application of triangular compounds

Abstract

The invention discloses applications of a peptides compound in rhizome sparganii in preparing anticoagulant and/or antithrombosis medicaments. The structural formula of the peptides compound is shown in the formula (I). The peptides compound obtained by separating and purifying rhizome sparganii, and applications thereof are provided for the first time, the compound plays a role in prolonging the prothrombin time (PT), activated partial thromboplastin time (APTT) and thrombin time (TT), has good anticoagulation activity, and provides a powerful basis for developing natural antithrombosis medicaments. The formula (I) is as shown in the specification.

Description

technical field [0001] The present invention relates to the technical field of medicine, and more specifically, relates to the application of a peptide compound in a triangular prism. Background technique [0002] Trigonum trigonum Sparganium stoloniferum The dried tuber of Buch.-Ham was first recorded in "Supplement to Materia Medica", and now it is recorded in "Chinese Pharmacopoeia". In addition to raw products and vinegar products used alone in traditional Chinese medicine, curcuma and astragalus are often used to enhance the curative effect. [0003] Modern pharmacological research shows that among the 35 commonly used drugs for promoting blood circulation and removing blood stasis, Sanleng ranks in the top 10 in terms of action strength, and is widely used in the treatment of cardiovascular and cerebrovascular diseases, tumors and various gynecological diseases. Especially for gynecological difficult diseases such as uterine fibroids and endometriosis, Sanleng has s...
