| titleOfInvention | A kind of preparation method of high-purity Rosaiwei |
| abstract | The invention discloses a preparation method of high-purity Rosaiwei. The rhizome of Rhodiola rosea is extracted by refluxing with an ethanol solution, and then extracted with petroleum ether and ethyl acetate respectively, and the extract is concentrated to obtain a crude extract of Rosaiwei; The crude extract of Rosaiwei is separated and enriched by macroporous adsorption resin and eluted with ethanol to obtain Rosaiwei eluate; Rosaiwei crude product is purified by preparative high performance liquid chromatography to obtain Rosaiwei refined product; Rosaiwei refined product is vacuum dried to obtain high-purity Rosaiwei. The Luosaiwei separated and extracted by the invention has high purity, the purity is more than 98.5%, and can be used as the standard sample of the Luosaiwei. |
