Abstract

The invention belongs to the technical field of plant drugs, and particularly relates to a method for extracting danshensu with high-purity from Salvia miltiorrhiza, which comprises the following steps: extracting solution is extracted from the Salvia miltiorrhiza medicine material containing danshensu by using a hot dripping method; the pH value of the extracting solution is adjusted by acid, the impurities are cleared and concentrated in a pressure reducing way; the eluting is carried out by using a macro porous adsorption resin and the danshensu is enriched; then concentration is carried out at low temperature, freezing and drying are carried out into solid; finally, ethanol is used for heating and dissolving, and the filter liquor is concentrated at low temperature after being filtered and precipitated, a crystallization is precipitated and the danshensu is obtained and the purity of the danshensu is more than 90 percent. The method for extracting danshensu with high-purity from Salvia miltiorrhiza has simple technology, high extracting efficiency, little pollution and low production cost, which can be controlled and is suitable for mass production.
