Characterization Of Pesticide Residues And Quantitative Study Of Phenolic Compounds Of Two Grapefruit Species: Citrus Paradisi Yellow And Citrus Paradisi Blood
Main Article Content
Citrus fruits and their juices are an important source of bioactive compounds; called secondary metabolites, including phenolic and non-phenolic compounds. Several studies have demonstrated the antioxidant properties of these citrus fruits. Grapefruit, scientifically called citrus paradisi, is one of those citrus fruits consumed primarily for its medicinal and antioxidant properties due to the presence of flavonoids, vitamin C and tannins. A characterization in phenolic compounds of two species of grapefruit, namely; citrus paradisi yellow and blood, was carried out by a quantitative study preceded by an assay of pesticide residues in order to enhance the value of the samples tested.
The results obtained showed the presence of a single pesticide; AZOXYSTROBINE with a content that does not exceed the required European standard (15 mg / kg of dry matter). In contrast, the characterization study of polyphenols demonstrated very potent antioxidant activity due to the presence of important phenolic compounds which may be the source of highly sought-after therapeutic properties and successful use in the medical and cosmetic fields.
