The experimental conditions of semi bionic extraction and ultrasonic-assisted semi bionic extraction of flavonoids from eucommia ulmoides were explored.For semi bionic extraction,the effect of extracting temperature,extracting time,and solid-liquid ratio on extraction efficiency was examined.For ultrasonic-assisted semi bionic extraction,the effect of ultrasonic time,ultrasonic temperature,and solid-liquid ratio on extraction efficiency was examined through the orthogonal test and single factor study.The experimental results showed that semi bionic extraction of 1∶20 (g∶mL) solid-liquid for 1.5 h at 60 ℃ yielded 325.0 mg/g flavonoid.The optimum conditions of ultrasonic-assisted extraction were extraction of 1∶40 (g∶mL) solid-liquid for 50 min at 65 ℃,and the content of flavonoids reached 264.4 mg/g.

Key words: eucommia ulmoides, flavonoids, semi bionic extraction, ultrasonic-assisted
