The present invention relates to an industrialized method for simultaneously producing Stevia rebaudiana chlorogenic acid and stevioside. Stevia rebaudiana is used as a raw material, extracted with alcohol, and the state of the raw material solution is adjusted so that chlorogenic acid is in a free molecular state, After extraction and separation with a water-insoluble medium polar organic solvent, Stevia rebaudiana chlorogenic acid is concentrated in the organic layer, and Stevioside is concentrated in the aqueous layer. The method prevents hydrolysis of the chlorogenic acid component of Stevia rebaudiana compared to the traditional water extraction process, thereby securing the active ingredient content and efficacy of the Stevia rebaudiana chlorogenic acid product. Under the premise of not affecting the quality and production efficiency of stevioside products, it realizes effective separation, improves production efficiency, and the proportion of isochlorogenic acid in the obtained product is close to the raw material, reduces the water consumption of production, and It is a high-profit eco-friendly production process by reducing the emission of flocculation residues.
