Abstract: The ultrasonic-assisted extraction of pigments from Acanthopanax senticosus Harms fresh fruit was optimized by employing a four-factor three-level Box-Behnken experimental design and response surface analysis. Results showed that the optimal extraction conditions were 37.5% ethanol as extraction solvent at a liquid/material ratio of 9:1 (mL/g), 170 W ultrasonic power and 43 min ultrasonic treatment time. The extract solution obtained under the optimal conditions revealed an absorbance of 0.791 at 525 nm.
