The valorization of agro-industrial residues is a key strategy not only to mitigate their environmental impact but also to obtain biomaterials and bioactive compounds of interest for the food, pharmaceutical, and nutraceutical industries. In this study, the feasibility of mangosteen (Garcinia mangostana) pericarp as a source of phenolic compounds was evaluated using ultrasound-assisted extraction (UAE). Two solvents (ethanol and ethanol/citric acid at pH 2.0, 3.5, and 4.0), two ultrasound frequencies (20 and 40 kHz), an extraction time of 30 minutes, and a solid-to-solvent ratio of 1:10 were tested. The highest total phenolic content (63.72 ± 3.43 mg gallic acid equivalents/g dry pericarp) was obtained with ethanol/citric acid at pH 3.5 and 20 kHz. 

Extract characterization (initially performed on the ethanol/citric acid extract at pH 3.5 and 20 kHz) was carried out using ultra-performance liquid chromatography coupled to mass spectrometry (UPLC-MS) and UHPLC-UV/Vis for the identification of anthocyanins and other polyphenols. The analysis revealed the presence of phenolic compounds, mainly anthocyanins and flavonols. Comparative quantification of the different extracts is currently underway to assess qualitative and quantitative variations in phenolic content as a function of extraction conditions. The results confirm the potential of mangosteen pericarp as a promising source of phenolic compounds with applications as nutraceuticals and natural colorants in the food industry.
