This invention relates to the field of biomedicine, specifically to the application of banana fruit extract in the preparation of anticoagulant or antithrombotic drugs. The banana fruit extract provided by this invention contains flavonoids, polyphenols, polysaccharides, hydroxyanthraquinones, triterpenoids, and other components. Flavonoids and polyphenols have been widely proven to have anti-inflammatory and antioxidant effects, which can synergistically enhance the anticoagulant effect. The high potassium content of banana fruit can indirectly improve vascular function by regulating sodium-potassium balance. The banana fruit extract provided by this invention can inhibit platelet production or promote platelet metabolism, prolong clotting time, and inhibit platelet aggregation. Its natural plant components interfere with platelet aggregation by inhibiting the production of thromboxane A2, achieving anticoagulant and antithrombotic effects. The mechanism of action of banana fruit extract differs from traditional anticoagulants such as heparin, reducing the risk of bleeding. Its natural component characteristics provide a direction for the development of novel plant-derived anticoagulant drugs.
