Abstract:

Euryale ferox planted in Suzhou was used as the raw material to extract flavonoids by ultrasonic extraction. The optimal extraction processing conditions for flavonoids from Euryale ferox were explored by orthogonal experiments. Results indicated that the impacts of factors on extraction rate from strong to weak were ultrasonic power, ethanol concentration, extraction temperature and extraction time. The optimal extraction processing parameters were ultrasonic power of 200 W, 80% ethanol as extraction solvent, extraction temperature of 40 ℃ and extraction time of 60 min. The extraction rate of flavonoids was 0.146 mg/g under the optimal extraction conditions.

Key words: Euryale ferox planted in Suzhou, flavonoids, ultrasonic extraction
