Abstract: In this study,Lonicera edulis was used to pigment by ultrasound-assisted ethanol extraction method.The extraction technology was optimized by using orthogonal test.Results showed that the opimal extraction conditions are as follows:extraction time 40 min,temperature 50 ℃,material to extraction solution 1:10;ultrasonic power 60 W and extraction stage 1.Compared with the traditional ethanol extraction method,the extraction rate of Lonicera edulis pigment is increased from 91.4% to 94.8% by this method,but the extraction time is shortened.

Key words: Lonicera edulis pigment, ethanol extraction, ultrasound-assisted
