This method can be coupled with the use of insoluble matrix, polyvinyl polypyrrolidone (PVPP; binds tannin-phenolics) for measurement of tannins (see below). The results can be expressed as tannic acid equivalent.
Folin's reagent or sodium 1,2-naphthoquinone-4-sulfonate is a chemical reagent used as a derivatizing agent to measure levels of amines and amino acids. The reagent reacts with them in alkaline solution to produce a fluorescent material that can be easily detected. This should not be confused with Folin-Ciocalteu reagent, that is used to detect WebNov 23, 2024 · Abstract. A single-laboratory validation of a method using Folin & Ciocalteu’s phenol reagent (Folin-C reagent) for determination of total phenolic content …
Webabsorption depends on the concentration of phenolic compounds. The reduced Folin-Ciocalteu reagent is detectable with a spectrophotometer in the range of 690 to 710 nm. The reaction temperature has been used to reduce the time necessary to attain the maximum color (T= 37°C). Generally, gallic acid is used as the reference standard WebMar 9, 2005 · Polyphenols, widely spread in our diet by the consumption of plant food products, are commonly determined using Folin-Ciocalteu reagent that interacts with other different reducing nonphenolic substances and leads to an overestimation of polyphenol content. In this paper we report an optimized Folin-Ciocalteu method to specifically …
