Solanum xanthocarpum fruits are used as the test material, and the extraction process of chlorogenic acid is studied in detail by using the ultrasonic-assisted ethanol extraction test method. Values of four group parameters for the volume solubility of ethanol aqueous solution, ratio of liquid to the material, ultrasonic time, ultrasonic temperature were adjusted, and then the proposed extraction process parameters of chlorogenic acid from single-factor experiments and the corresponding results were optimized. The optimized parameters were ethanol concentration 65%, ratio of liquid to material 50 mL/g, ultrasonic temperature 60 ℃ and ultrasonic time 40 min. On the basis of the above single factor optimization results, the final quadratic multiphase mathematical model was obtained further by optimization from the Box-Behnken response surface method. The extraction process parameters were ethanol concentration 64.7%, liquid-to-solid ratio 55.8 mL/g, and ultrasonic temperature 56.0 ℃ for 40.5 min, and the optimal extraction rate of chlorogenic acid was 6.81%. The extract of S. xanthocarpum fruits had good antioxidant capacity to DPPH and ABTS free radical scavenging with IC50 values of 55.7 mg/L and 20.1 mg/L, respectively.
