Ultrasonic wave assisted extraction and microwave assisted extraction are emerging in recent years extractive techniques.From dried material, extract target compound and roughly be divided into two steps: the 1) infiltration of material, the i.e. expansion of material and aquation; 2) the solubility target compound is by diffusion, the mass transport process of infiltration from the material to the solvent.Studies show that ultrasonic wave both can promote the expansion and the aquation of dried material, can promote mass transport process again.We find by Electron Microscopy in the laboratory that ultrasonic wave can make plant cell wall produce hole, helps the stripping of target compound in the cell, can promote mass transport process.In addition, ultrasonic wave can also reduce raw meal particle size, thereby increases the contact area of material and solvent, helps the extraction of target compound.That the ultrasonic wave assisted extraction has is easy to operate, with low cost, extraction time short, be easy to amplify advantage such as production.Ultrasonic wave extraction element commonly used at present comprises sonde-type extraction element and water-bath type extraction element.The former probe sphere of action is limited, is unfavorable for amplifying producing; The ultrasonic vibration that the latter produces can must just can be passed to sample by medium and sample bottle, and this indirect ultrasonic wave mode of action may influence extraction efficiency.
