Optimization of ultrasound-assisted extraction method for phytochemical compounds and antioxidant activities of sour jujube extracts.

ABSTRACT: Ultrasonic-assisted extraction is a rapid and effective extraction method that uses ultrasound energy and solvents to extract target compounds from various plant matrices. In this study, the ultrasonic-assisted extraction conditions of sour jujube were optimized. A five-level central composite design (CCD) with four variables was used to evaluate ultrasonic treatment variables influencing the total saponin content (TSC), total flavonoid content (TFC), and total phenolic content (TPC) extracted from sour jujube. The solvent concentration, extraction time, ultrasonic power, and solid-to-liquid (S/L) ratio were optimized using aqueous ethanol and methanol solutions as extraction solvents. A central composite design (CCD) was used for an in-depth study, and then the optimal value that could pr
