Effect of extraction solvent. (A) Effect of the1-undecanol volume on the analytical signal in the determination of thymol (5.0 mg L−1) and carvacrol (5.0 mg L−1). Experimental conditions: disperser solvent (acetone) = 0.50 mL; (NaOH 1.0 M) pH 7.0; % NaCl = 7.0%; sample volume = 5.0 mL; ultrasound duration time = 10.0 min; centrifugation duration time (800 rpm) = 7.5 min (n = 3). (B) Effect of the dilution of the analytes on the optimization of the extraction solvent (1-undecanol) volume in the determination of thymol and carvacrol.
