A rapid microtitre plate Folin-Ciocalteu method for the assessment of polyphenols [PDF]
AbstractSeveral methods have been described for the determination of phenolic compounds in animal and plant products using the Folin-Ciocalteu (FC) assay. Most of these methods describe the use of this reagent and sodium carbonate in spectrophotometric methods. The macro FC assay was compared with two micro FC assays carried out on a microplate reader.

A Modified Folin-Ciocalteu Assay for the Determination of Total Phenolics Content in Honey
The Folin-Ciocalteu assay is a widely used method for measuring the total phenolic content (TPC) in honey, but it can be affected by the presence of reducing sugars in honey, which can lead to interference and an over-estimation of its TPC.
