Ultrasound-Assisted Extraction of Total Saponins from Aralia taibaiensis : Process Optimization, Phytochemical Characterization, and Mechanism of α-Glucosidase Inhibition.

The optimal extraction conditions identified here established a basis for future scale-up of ultrasound extraction parameters with the potential for obtaining maximum yields. In vitro enzyme inhibition experiments investigated the mechanism of the TSAT interaction with α-glucosidase and further explored whether araloside A may be the main contributor to the good inhibition of α-glucosidase activity by TSAT.
