Zusammenfassung: | The invention relates to an extraction method of salvia plebeia general flavone extract. The extraction method comprises the following steps: after smashing an aboveground part of salvia plebeia, decocting with water, concentrating to obtain a salvia plebeia concentrate, enabling the salvia plebeia concentrate to pass through pretreated polyamide, washing a polyamide column, then using an eluent for elution, collecting a solution after elution, and concentrating to be dry, thus obtaining the salvia plebeia general flavone extract. Compared with the existing extraction method, the method for preparing general flavone in salvia plebeia provided by the invention has the following obvious advantages: firstly, polyamide resin has the characteristic of strong specificity, and can be used for effectively adsorbing and removing compositions of phenolic acids and saponins in extract, while macroporous resin does not have such capability; secondly, extraction solvent water is used for replacing ethanol so as to not onl |
