As the extract solvent, Acetone is used primitively to extract Silymarin since their  introduction to China in 20th century. Compare to the Silymarin extracted by Ethanol and the Silymarin extracted by Ethyl Acetate, the price for the Silymarin extracted by Acetone is the cheapest, and the consuming of this specification is the biggest in the whole world. But because Acetone has some toxicity, it is un healthful, so in the future, it will be replaced by the Ethanol or the Ethyl Acetate gradually.
