Optimization of Ultrasonic-Enzyme Synergistic Extraction of Proanthocyanidins from Jujube: Purification, Characterization, and Bioactivity Study.

As can be seen from Table S1 , in the regression model, p < 0.01 indicates that the difference between the quadratic regression equation models is highly significant.

Effects of Ultrasound Time, Power, and Temperature From Figure 1 D, the yield of proanthocyanidins showed a trend of increasing and then decreasing with increasing ultrasound time, and when the ultrasound time exceeded 30 min, the yield of proanthocyanidins instead began to decrease, which was attributed to the fact that excessive prolongation of the ultrasound time triggered the oxidation or degradation of proanthocyanidins [ 19 ].
