TABLE 5.

Experimental values and predicted values of response variables at optimum extraction conditions

Response variables Optimum extraction conditions Experimental value Predicted value
X 1 X 2 X 3 X 4
YTFC 72% 35 ml/g 41 min 500 W 9.10 ± 0.13 8.89
YDPPH 80.33 ± 0.41 79.27
YOH 24.28 ± 0.22 25.19

Note: X 1: ethanol concentration (%); X 2: solvent‐to‐material ratio (ml/g); X 3: ultrasonic time (min); X 4: ultrasonic power (W). The experimental results were all expressed as mean ± standard deviation (n = 3).
