Spectrophotometry

Total polyphenols analysis

TECHNIQUE

Total polyphenols can be determined by colorimetric analysis with Folin-Ciocalteu reagent. Generally, given the complexity of the samples is necessary to eliminate interferences (oxidable compounds) filtering them through solid phase extraction cartridge (SPE). The results are expressed in milligrams of gallic acid equivalents per liter of sample.

ANALYSIS

We perform qualitative and quantitative analysis of polyphenols and carotenoids in a wide variety of food and biological matrices (citrus, grapes, wine, urine, plasma, etc.).
