Ethanol extraction is a widely employed technique for separating and purifying active compounds from plant materials. This method utilizes ethanol (alcohol) as a solvent to extract target compounds from raw materials, yielding purer products. Ethanol extraction finds extensive applications in pharmaceutical preparation, natural product purification, as well as the manufacturing of flavors and fragrances.
