Problems solved by technology

The difference in types of saponins in Panax notoginseng and Pingbian notoginseng will lead to differences in their functions and indications, and the two cannot be mixed
At present, scholars at home and abroad are focusing on their chemical composition, planting method, rapid identification method, conservation method, drying method, anti-inflammatory activity, anticancer activity, and blood lipid and blood sugar lowering activity. There is no report on the antithrombotic effect of Pingbian Sanqi

Abstract

The invention relates to a preparation method of total saponins of panax stipuleanatus and application of an anticoagulant drug, and belongs to the technical field of biological medicine. The preparation method comprises the steps that panax stipuleanatus powder is added into an extraction solvent, microwave extraction is carried out for 20-40 minutes at 60-100 DEG C, filtration is carried out toobtain residues and an extracting solution, then the residues are extracted 2-3 times in the same extraction condition, the extracting solutions are mixed, then decompression concentration is carriedout to obtain an extract, saturated n-butanol is used for extracting the extract to obtain a n-butanol extract, the n-butanol extract is separated by adopting MCI column chromatography, an ethanol / water solvent system is used for elution to obtain ethanol eluent, and the ethanol eluent is concentrated and dried to obtain the total saponins of the panax stipuleanatus. The total saponins of the panax stipuleanatus can be used for preparing a drug composition for treating thrombotic diseases and / or resisting blood coagulation.

Description

technical field [0001] The invention relates to a preparation method of Panax notoginseng total saponins and the application of anticoagulant drugs, belonging to the technical field of biomedicine. Background technique [0002] Thrombus is the deposition of fibrin and formed components of blood in blood vessels. Dysfunction of anticoagulant factors and fibrinolytic system can lead to diseases such as stroke, thrombosis and myocardial infarction. At present, the fatality rate of thrombosis is second only to nausea, tumor and myocardial infarction. Anticoagulants can inhibit the generation of thrombin and fibrin formation, thereby accelerating the dissolution of thrombus. The clinical drugs used for anticoagulation on the market have relatively large side effects and can easily induce diseases such as hemorrhage and hyperkalemia. However, natural anticoagulant drugs are rich in sources, have high efficiency and low toxicity, and have great potential in the treatment of throm...
