PALMEIRA, S. M. V.; GOIS, L. M.  and  SOUZA, L. D.. Extraction of phenolic compounds from mango peels. Lat. Am. appl. res. [online]. 2012, vol.42, n.1, pp. 77-81. ISSN 1851-8796.

Scientific studies have shown that mango peel is a rich source of phenolic compounds, which present antioxidant activity. In order to contribute to the future applications of this material, this paper aims the optimization of the extraction process of phenolic compounds from mango peels. The following process parameters were evaluated in this study: mango variety, peel drying time, ethanol concentration and solvent temperature. A two-level, four-factor full- factorial design (2⁴) was used in the design of the experiments and in the analysis of the results. With the preliminary results a star experimental design around the central point was performed to obtain a response surface. A maximum extraction yield of 33.7% of total phenolics was obtained for the "Espada" variety, with ethanol concentration of 70% and 10 hours of mango peel drying time.
