Abstract
This work aimed to evaluate the optimum conditions for efficient extraction of phenolic acids, namely gallic acid (GA) and tannic acid (TA) from Aleppo oak by ultrasonic-probe assisted extraction (UPAE) method. Furthermore, an extensive study on kinetic, antioxidant activity and cost evaluation aspects in comparison with classical hydro-distillation extraction (CHDE) method was also examined. Sonication demonstrated a superior effect on the extraction of target compounds in which the UPAE method was seven times more efficient compared to the classical hydro-distillation extraction (CHDE) method. Result revealed that under optimized optimum condition of 40% duty cycle and 70 °C extraction temperature, GA and TA were yielded at 870.90 ± 0.03 mg GAE/g and 3157.97 ± 0.05 mg TAE/g, respectively. Kinetic analysis affirmed the extraction rate as controlling factor in extracting phenolic acids. Strong antioxidant activity was observed at a IC50, 26.57 ± 0.03 μg/mL. Besides, the cost assessment study indicates that the extraction process requires US$ 0.25 and US$ 0.06 per mg/g extracts produced for CHDE and UPAE, respectively. Notably, findings revealed that UPAE method is four-fold more cost-effective compared to the CHDE method, providing a new direction for extracting active compounds from complex plants.
