Table 5

Comparison of the EEs obtained using 40% ethanol and DES-F under the optimized conditions.

	Liquid-solid ratio	Water content	Exaction time	Extraction efficiency
				Predicted	Measured
DES-F	31.18	32.74	43.10	17.68
DES-F	31.00	33.00	43.00		17.37 ± 0.64
40% ethanol	31.00	40%	43.00		13.70 ± 0.08

Measured values are represented as mean ± standard deviation.
