Brazil is in a privileged position regarding the generation and potential full use of biomass, since it has a large amount of plant residues of different natures. Among these, agro-industrial wastes occupy a prominent place, which present natural products that offer benefits to human health. Thus, this project has as main objective the development, optimization and application of green methods for the extraction of bioactive compounds from Passiflora peel (passion fruit), considering the principles of Green Analytical Chemistry. The methods based on ultrasonic extraction and microwave assisted extraction (MAE) for the isolation of flavonoids isoorientin and orientin of the raw material will be used and evaluated by means of metrics such as the Green Star, to verify the green character of each procedure which will be compared with a conventional extraction method (ultra-turrax).
