Ultrasound extraction, with its unique advantages of low extraction temperature, high extraction rate and short extraction time, is used to extract the effective content of Chinese medicinal materials, oil, various animals and plants. It is a modern high-tech means to replace traditional shearing process and achieve efficient, energy-saving and environmental protection extraction. The superiority of ultrasonic extraction of Chinese medicinal materials is based on the special physical properties of ultrasound. It mainly reduces the interaction force between the target extract and the sample matrix through the fast mechanical vibration wave generated by piezoelectric transducer to achieve solid-liquid extraction separation. The simple method and mechanism of ultrasonic extraction of Chinese medicines and natural medicines are as follows: adding extraction solvent (water, ethanol or other organic solvents) into the container, crushing or cutting Chinese medicines into granules according to need, and putting them into the extraction solvent; adhering the transducer oscillator to the outer wall of the container or sealing the oscillator in the stainless steel box and putting it into the container; opening the ultrasonic generator
, and extracting the oscillator to the container. Ultrasound is emitted in the solvent, which can effectively break the cell wall of medicinal materials and dissolve the active ingredients into the extracting solvent. On the other hand, it can accelerate the molecular movement of the extracting solvent, and make the extracting solvent and the effective ingredients in medicinal materials contact quickly, dissolve and mix with each other.
