Method for extracting herbaceous plants for external application by using small molecule cutting technology

Abstract

The invention discloses a method for extracting herbaceous plants for external application by using small molecule cutting technology. The method comprises the following steps: crushing herbaceous plants, adding a first solvent into the crushed herbaceous plants for grinding so as to obtain slurry, filtering the slurry and recovering a filtrate; separating the first solvent and a solute in the recovered filtrate and subjecting the separated solute to micro laser irradiation; and dissolving the irradiated solute in a second solvent to form a solution, successively stirring and standing the solution, separating the second solvent from a solute and recovering the solute which is an element-level active component. Through the micro laser irradiation and cutting of the solute after separation of the first solvent, the solute reaches the element level and maintains its activity and efficacy.
