Abstract

The invention relates to a method for extracting medicine for treating human cardiovascular diseases from thalictrum robustum. The method comprises the following steps that thalictrum robustum is subjected to ultrasonic extraction and cation exchange resin desorption, wherein the solvent of the ultrasonic extraction is ethanol, the ultrasonic frequency is 25 to 35 kHz, the cation exchange resin desorption adopts sodium hydroxide water solution, and hydrochloric acid is adopted for desorption in desorption solution. According to the method, through ultrasonic extraction and cation exchange resin active ingredient adsorption, the finally obtained extracts can be used for effectively preventing and treating hypertensive diseases. The method has the advantages that the steps are simple, the influence on the activity of active ingredients is small, and the active ingredients of the extracts cannot be weakened, Compared with the existing extracting method, the method obtains the outstanding progress.

Description

technical field

[0001] The invention belongs to the field of medicine preparation, and in particular relates to a method for extracting medicine for treating human cardiovascular diseases from Tangsongcao bracken. Background technique

[0002] At present, there are many methods for extracting medicines from plants of the genus Echinacea, for example: the method disclosed in CN101278989A, which is to add Echinacea to a polar organic solvent for extraction, stir with water into a crude extract suspension, and pass through the adsorption resin successively. Separate the separation column and cation exchange resin to obtain total saponins; use 1-10% NaOH aqueous solution or organic solvent to analyze the cation exchange resin, and then acidify the analysis solution with hydrochloric acid or sulfuric acid to obtain the total alkaloid extract; the above organic Solvents include methanol, ethanol, and the like.

[0003] This method is not very ideal for extracting the effective co...
