Abstract

An efficient extraction and purification technique based on ultrasonic microwave-assisted extraction (UMAE) method was established to obtain phenolics-enriched fraction from jackfruit by-products (JPEF). Optimisation of the extraction parameters for maximum extraction yield of JPEF was carried out using response surface methodology (RSM). Results demonstrated that the optimum conditions were: ethanol concentration of 63%, solvent-to-solid ratio of 34 mL/g, microwave power of 160 W and irradiation time of 20 min. Under the optimal extraction conditions, the phenolics extraction yield was 8.14 mg GAE/g DW. Compared to conventional extraction methods, UMAE provided higher extraction efficiency and activity. The results demonstrated that UMAE is a green method and have great potential for the extraction of active components and antioxidants from natural products.
