Optimizing the extraction of phenolic compounds from Bixa orellana L. and effect of physicochemical conditions on its antioxidant activity

For this work, the surface response methodology was applied in order to optimize the extraction using solvents of phenolic compounds present in Bixa orellana L. seeds through a central composite design that evaluated the effect of the factors: extraction time (36 to 60 h) and the solvent ml/g seed ratio (2/1 to 4/1), for the response variable total phenol content extracted from the seed. The levels on the factors that...
