Abstract: Objective: To make comprehensive utilization of Chaenomeles sinensis (Thouin) Koehne. Methods: Box-Behnken experimental design and response surface methodology were used to optimize ultrasonic-assisted extraction conditions of simultaneous extraction for flavonoids and polysaccharides from Chaenomeles sinensis (Thouin) Koehne. Results: The optimal extraction conditions were ultrasonic power of 480 W, extraction time of 35 min, extraction temperature of 73 ℃ and materialliquid ratio of 1:90 (g/mL). Under these optimal conditions, the total yield of flavonoids and polysaccharides was up to 15.62%, an increase of 21.46% when compared with hot water extraction. Conclusion: The total yield of flavonoids and polysaccharides during the simultaneous extraction from Chaenomeles sinensis (Thouin) Koehne is improved by ultrasonic-assisted extraction.

Key words: Chaenomeles sinensis (Thouin) Koehne, flavonoids, polysaccharides, ultrasonic-assisted extraction, extraction rate
