Microwave-assisted ionic liquids pretreatment followed by hydro-distillation for the efficient extraction of essential oil from Dryopteris fragrans and evaluation of its antioxidant efficacy in sunflower oil storage

► A novel MILP-MHD technique is first developed for the extraction of essential oil. ► Optimization and modeling the method by central composite design and kinetics. ► Procedure benefits: higher yield, shorter duration and safe constituents. ► A potential and green technique for the fragrances isolation and flavor industries. ► A potent natural antioxidant to prevent the oxidation of edible oils in storage.
