Abstract: The extraction technology of flavonoids in Ginkgo biloba leaves was studies in this paper. In comparison with the soxhletextraction technology, The results showed the supersonic method was superior to the soxhlets technology. It was found that theextracting conditions with 40KHZ supersonic waves for 10 min and static balance for 12h were optimum.

Key words: Ginkgo biloba leaves , Flavonoids , Supersonic wave , Extraction technology
