The purpose of this research was to obtain extracts of flavonoids from orange tangelo peelings (Citrus reticulata x Citrus paradisi) and apply them as natural antioxidant to the vegetable oil Sacha inchi (Plukenetia volubilis). The information was obtained from experimental tests which were made in seven steps: physical and chemical characterization of the orange tangelo and the sacha inchi oil; extraction of flavonoids by the Soxhlet extractor; detection of flavonoids in each extract through fine layer chromatography and paper chromatography; identification and quantification of flavonoids by high resolution chromatography liquid (HPLC); determination of the antioxidant capacity of each extract of flavonoid, and finally evaluation of the antioxidant activity in oil sacha inchi, of the extract with the higher level of antioxidant capacity using a multifactorial design with two factors: e...
