Research on Controllable Effects of HI Ultrasonic Radiation to Active Composition in Hippophae
The controllable cavitation effects of high intensity ultrasound are introduced. The effects are used for active component extraction of biomaterials. The research aims: combining with extraction of the total flavones from hippophoe leaves, the effects to chemical structure of active components with HI ultrasonic radiation are deeply explored. The research contents: ①the reaction mechanism of HI ultrasound to plants and ②the effects of cavitation to active composition of hippophae will be discussed. The research methods: ①through the theory and experiment research, the characters of HI ultrasonic energy ere introduced, and then ②the chemical structures of total flavones from Hippophoe leaves extracted with ultrasound are tested by means of HPLC. The results: ①the characters of ultrasonic energy could be controlled and ②at the reasonable conditions, the active ingredients of plant medicine will not be destroyed by ultrasound.
