Flavonoids and Polyphenols

<p>Stability Light Sensitive<br>Applications Minor constituent of wine, correlated with serum lipid reduction and inhibition of platelet aggregation. Resveratrol is a specific inhibitor of COX-1, and it also inhibits the hydroperoxidase activity of COX-1. It has been shown to inhibit events associated with tumor initiation, promotion and progression.<br>References Powell, R.G., et al.: Phytochemistry, 35, 335 (1994), Jeandet, P., et al.: J.

<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.

<p>Applications Ferulic Acid 4-O-β-D-Glucuronide is a metabolite of Ferulic Acid (F308910) and Caffeic Acid (C080000). Ferulic Acid 4-O-β-D-Glucuronide is one of the circulating metabolites in human plasma after coffee consumption.<br>References Su, M. et al.: Zhong. Zian. Ying.

<p>Applications Isovitexin is known as a flavones, a class of flavonoids. Isovitexin have been studied for their antiradical activities in the process of metabolisms. Isovitexin have also been studied for beneficial effcts against atherosclerosis, osteoporosis and certain cancers.<br>References Cermak, R., et al.: Expert. Opin. Drug. Metab.
