Abstract

The invention discloses an application of an active peptide compound in rhizoma sparganii to the preparation of anticoagulant and/or antithrombotic drugs. The active peptide compound has the structural formula (I) shown in the specification. The invention firstly provides the peptide compound obtained from the rhizoma sparganii by separating and purifying and the application of the peptide compound. The compound has a trend prolonging effect for the prothrombin time (PT), activated partial thromboplastin time (APTT) and thrombin time (TT), has favorable anticoagulation activity and provides a powerful basis for the development of natural antithrombotic drugs.

Description

technical field [0001] The invention relates to the technical field of medicine, and more specifically, relates to the application of a peptide active 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 sh...
