Abstract

The present invention features that based on the property of total salvianolic acid, which is a kind of weak acid, may be reacted with alkali to form salt with high stability and has high dissolvability in water; red sage is first extracted with alkali solution and then extracted with resin column, and safflower is ethanol refluxed to maintain its chalcone dimmer and other effective component and then acid solution extracted; and the safflower extract liquid and the red sage extract liquid are finally resin column extracted to raise the content of salvianolic acid, flavone and other effective components. The present invention provides a kind of red freeze dried sage-safflower powder for injection for clinical application in treating coronary heart disease, angina pectoris, cerebral vascular diseases and other diseases.

Description

[0001] Field [0002] The invention belongs to the field of traditional Chinese medicine pharmacy, and specifically relates to a danhong injection freeze-dried powder containing effective parts of salvia miltiorrhiza and safflower and a preparation method thereof. Background technique [0003] Salvia miltiorrhiza is the dry root and rhizome of Salvia miltiorrhiza, according to the existing literature: Salvia miltiorrhiza was first recorded in "Shen Nong's Materia Medica", and many herbal medicines have been recorded in successive dynasties.
