Problems solved by technology

[0009] 2. Effects on blood and hematopoietic system
The patent also describes the preparation method of the composition. This invention adopts the method of separating and purifying the components first, and then mixing them. This not only discards many active ingredients, but also makes the preparation cost quite high
[0025] In addition, the total saponins of Panax notoginseng in the prior art contain 5 quantifiable components, with a total content of 65% to 80%, and a considerable proportion of unknown impurities. Many problems have been brought about in quality control and application, which increases the probability of adverse reactions such as skin allergies, chills, papules, palpitations, shortness of breath, etc.

Abstract

The invention provides a medicinal composition, which comprises the following components: ginsenoside Rb1, ginsenoside Rg1, notoginsenoside R1, ginsenoside Rd, ginsenoside Re, ginsenoside Rf, ginsenoside Rc, ginsenoside Rh1, ginsenoside Rb2 and ginsenoside Rg3. The invention also provides a preparation method for the medicinal composition. The medicinal composition has definite components; compared with the total notoginsenoside in the prior art, the medicinal composition has stable quality and good controllability; and results of experiments of acute toxicity, undue toxicity, hemolysis and the like show that the medicinal composition has higher safety and wide clinical application prospect.

Description

technical field [0001] The invention relates to the field of medicine, in particular to a pharmaceutical composition and a preparation method thereof. Background technique [0002] Panax notoginseng, ginseng and American ginseng belong to the genus Araliaceae, and all three are valuable Chinese medicinal materials. Modern studies on the chemical constituents of Panax notoginseng and ginseng have shown that Panax notoginseng saponins are similar to ginsenosides, both of which are mainly dammarane-type saponins, but the total saponins content of Panax notoginseng is high, and the meaningful ginsenoside Rb1 and Rg1 was higher than that of ginseng. [0003] Saponin is one of the main active components of Panax notoginseng. In addition, it also contains notoginseng, an effective hemostatic component, as well as polysaccharides, amino acids, volatile oils, flavonoids and trace elements. The monomeric saponins extracted and separated from Panax notoginseng include ginsenosides Rb...
