Flavonoids and Polyphenols

<p>Applications Labelled Ferulic acid (4-hydroxy-3-methoxycinnamic acid or, in IUPAC nomenclature, 3-(4-hydroxy-3-methoxy-phenyl)prop-2-enoic acid) which is a highly abundant phenolic phytochemical which is present in plant cell walls. It may have significant health benefits through its antioxidant and anti-cancer activity, and may also serve as a precursor in the manufacturing of useful aromatic compounds. Used as an antioxidant.<br>References Smart, M.G., et al.: Aust. J. Plant Physiol., 6, 485 (1979), Chen, C., et al.: J. Food Lipids, 2, 35,1995, Benzie, I., et al.: Anal.
