Citrus Extract Powder
citrus extract powder Brief Introduction Polyphenols are a structural class of natural, synthetic, and semisynthetic organic chemicals characterized by the presence of large multiples of phenol units. The number and characteristics of these phenol substructures underlie the unique physical, chemical, and biological (metabolic, toxic, therapeutic, etc.) properties of particular members of the class. The term polyphenol derives from poly-, from the ancient Greek word and the word phenol which refers to a chemical structure/substructure formed by attaching to an aromatic phenyl or benzenoid ring an alcohol-type hydroxyl (-OH) group (giving rise to the "-ol" suffix). The term "polyphenol" has been in use since 1894.
