Optimization of water-based ultrasonic-microwave assisted extraction (UMAE) of bioactive compounds from Garcinia mangostana pericarp.

Overall, the synergistic effect of ultrasonic and microwave extraction resulted in a significantly higher amount of bioactive compounds when compared to conventional decoction extraction (p≤0.001). These results demonstrated the advantages of UMAE for preparing GM pericarp extract for the food, cosmetic and pharmaceutical industries.
