Abstract

An application of ruscorectal and / or its heteroside prepared from ruscorectal and saccharide chain in preparing the medicine for preventing and treating thrombotic diseases is disclosed.

Description

technical field [0001] The invention relates to the application of ruscogenin and its saponins derived from traditional Chinese medicines in the preparation of medicines for preventing and treating thrombosis diseases, specifically the application of ruscogenin and ophiopogon saponins in the preparation of medicines for preventing and treating venous thrombosis diseases. technical background [0002] Thrombotic disease is a common disease and frequently-occurring disease, clinically, venous thrombotic disease is especially common, and the lower extremities and pelvic cavity are its predilection sites. The acute phase of deep vein thrombosis (DVT) in the lower extremities is characterized by pain, swelling, and superficial varicose veins in the affected limbs. Insufficiency, superficial dermatitis, and induration caused by fibrosis, etc., can cause gangrene and loss of working ability in severe cases, and even cause sudden death due to pulmonary embolism due to emboli falling...
