摘要
The paper presents results concerning ultrasonically assisted extraction of bioactive compounds from roots of valerian. Pulsed ultrasonic field was applied. The investigation was accomplished by varying irradiation time and sonic power. The results were compared with classical (silent) extraction. The study included evaluation of the coefficient of rehydratation, yield of extraction, dry matter content in extract and residue, and unit energy consumption. The utilisation of pulsed ultrasound was proved to be a more efficient technique than the classical method for extraction of bioactive components from dried valerian roots.
