| Abstract: | With the content of flavonoid as index,the ultrasonic-assisted extraction of flavonoids from eucommia leaf is investigated.The effects of alcohol concentration,ratio of solid to liquid,ultrasonic wave time and ultrasonic wave temperature on the extraction of flavonoid are studied respectively.The extraction process is optimized through orthogonal test.The optimum conditions of flavoid extraction are pointed out as follows：alcohol concentration 65%,ratio of solid to liquid 1∶25,ultrasonic wave time 35 min and ultrasonic wave temperature 65℃.Under the above conditions,the extraction rate of flavonoids can come up to 2.28%. |
