Objective: To optimize the extractive condition of flavonoids from Morus alba. Methods: UV were established to determine total flavonoids,U( 94) Uniform design form was selected as the experiments' schedule,the total flavonoids was used as evaluation indicator to and the extraction solvent concentration,extraction time,solid-liquid ratio and particle size was used as the 4 influencing factors. Results: The uniform design experiment show that ethanol concentration of 90%,the extration time of 8 hours,the sol...
