Abstract: The functional component in propolis is mainly composed of flavone. The functional component is extracted withalcohol traditionally and it is low-efficiency process. Ultrasound technology can be used in the extraction process under thefollowing conditions: power 750W, propolis:alcohol 1:15(W:V), time 15mins. The extraction ratio and the content of total flavoneare improved significantly.

Key words: propolis, ultrasound, extraction
