[5] [7] In total, between 50,000 [8] and 130,000 [9] phytochemicals have been discovered. Phytochemists study phytochemicals by first extracting and isolating compounds from the origin plant, followed by defining their structure or testing in laboratory model systems, such as in vitro studies using cell lines or in vivo studies using laboratory ...
Other tests measure the antioxidant capacity of a fraction. Some make use of the ABTS radical cation which is reactive towards most antioxidants including phenolics, thiols and vitamin C. [25] During this reaction, the blue ABTS radical cation is converted back to its colorless neutral form. The reaction may be monitored spectrophotometrically.
[3] [4] [5] By non-antioxidant mechanisms still undefined, polyphenols may affect mechanisms of cardiovascular disease or cancer. [ 6 ] The increase in antioxidant capacity of blood seen after the consumption of polyphenol-rich (ORAC-rich) foods is not caused directly by the polyphenols, but most likely results from increased uric acid levels ...
Lamaison and Carnet have designed a test for the determination of the total flavonoid content of a sample (AlCI 3 method). After proper mixing of the sample and the reagent, the mixture is incubated for ten minutes at ambient temperature and the absorbance of the solution is read at 440 nm. Flavonoid content is expressed in mg/g of quercetin.

Lycopene is an antioxidant commonly found in tomatoes — it has been shown to prevent cell damage and provide myriad benefits to the body, including but not limited to helping improve sperm count.
The Folin–Ciocâlteu reagent (FCR) or Folin's phenol reagent or Folin–Denis reagent, is a mixture of phosphomolybdate and phosphotungstate used for the colorimetric in vitro assay of phenolic and polyphenolic antioxidants, also called the gallic acid equivalence method (GAE). [1] It is named after Otto Folin, Vintilă Ciocâlteu, and Willey ...
7. It has anti-aging properties. Although there’s no shame in aging, moringa is packed with antioxidants like flavonoids and polyphenols, which may combat premature wrinkles and keep your skin ...
