Problems solved by technology

Many medical workers hope to develop salvianolic acid A and salvianolic acid B into new traditional Chinese medicines, especially the combination of salvianolic acid A and salvianolic acid B, but there are great doubts: (1) salvianolic acid A and salvianolic acid B are compounds with strong antioxidant activity in nature. They are easy to be oxidized, unstable in aqueous solution, and easier to degrade during high temperature sterilization. Therefore, their stability has become a technical barrier that is difficult to overcome. Whether the combination can avoid degradation and oxidation and make the two more stable; (2) Salvianolic acid A and salvianolic acid B belong to the active ingredients of the same traditional Chinese medicine, and their pharmacological activity and other properties are similar. Is there a certain internal relationship between the two combinations? , whether the combination can play a greater role through a certain combination, rather than a simple combination of 1+1=2; (3) Salvianolic acid A and salvianolic acid B enter the body through a certain combination, and their absorption and distribution Whether there are new changes in , metabolism, etc.; and many other problems have plagued medical researchers, and the combination of the two cannot be developed into a clinically safe and effective pharmaceutical preparation
[0004] Chinese patent "A method for extracting phenolic acid components from the traditional Chinese medicine Salvia miltiorrhiza and its freeze-dried powder injection" (application number 03132382.0) discloses the preparation of freeze-dried powder injection by combining salvianolic acid A and salvianolic acid B, but its main It is to study how to extract salvianolic acid A and salvianolic acid B from Salvia miltiorrhiza, and the combination of salvianolic acid A and salvianolic acid B has only been studied briefly through pharmacological experiments: the more the amount of salvianolic acid B in the combination, the better the pharmacological effect; The research is just a simple superposition of the active ingredients of Danshen, and the in-depth study of the combination of active ingredients has no practical significance

Abstract

A medicinal composition for the orally taken medicines in the form of tablet, capsule, particle, micropill, dripping pill, etc contains danshinolic acid A and dashinolic acid B. Its preparing process and quality control method are also disclosed.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine pharmacy, in particular to a pharmaceutical composition containing salvianolic acid A and salvianolic acid B as effective components of traditional Chinese medicines and a preparation method for oral preparation thereof. Background technique [0002] The active ingredients of traditional Chinese medicine are monomeric compounds extracted from traditional Chinese medicine. On the basis of retaining the functions of traditional Chinese medicine, they have the characteristics of high content, strong activity, and clear targets. Under the guidance of TCM theory, the development of active ingredients into clinically safe and effective TCM preparations is of great significance in the modernization of TCM. [0003] The chemical components of Danshen can be mainly divided into water-soluble components and fat-soluble components. As we all know, the traditional application method of Da...
