Abstract: To study a new extraction method of mistletoe flavonoids by ultrasonic technology. Orthogonal test was used to evaluate the influence of the 3 factors, including the concentration of ethanol, the extracting time by ultrasonic, and the rate of solid and liquid. The results showed that the optimum extraction is as follows: adding 80% ethanol into mistletoe, extracting 30min; the rate of solid and liquid 1:40.

Key words: mistletoe, flavonoids, ultrasonic extraction
