  • Patent number: 9765062
    Abstract: The present invention relates to a method for producing silymarin. The method comprises: pressing silybum marianum seeds to obtain silymarin powder, and soaking the silymarin powder by using alkaline water; extracting, by using acetone, the silymarin powder soaked by using alkaline water, and performing filtering and concentration on the extracted liquid to obtain a concentrated solution; and performing extraction on the concentrated solution by using a non-polar solvent, performing separation to obtain a non-polar solvent layer and an acetone layer, and concentrating and drying the acetone layer to obtain silymarin. The method can greatly improve the extraction efficiency and the yield, shorten the extraction time, needs simple processes and low cost and thoroughly remove residual oil, so that the product has a low impurity, high product quality and a high purity; and the method is applicable to industrial production and has a great application prospect and economic value.
