The differences in composition presented between the extracts reported in the literature and in the present study may be due variety, degree of ripeness of the fruit used and the method of extraction. An important factor is the solvent used for the extraction of phenolic compounds, because solvents with different polarity extracted different compounds in varying quantities [25]. Another factor to consider is the hydrolysis with acids and bases [26], a step that was performed to development of the ethanolic extract, in where the tannins present in the mango seed could be hydrolyzed to simpler compounds such as gallic acid.
