Natural phenols, bioavailable phenols, plant phenolics, low molecular weight phenols or phenoloids are small molecules containing one or more phenolic group. These molecules are smaller in size than polyphenols, containing less than 12 phenolic groups. They can be classified as simple phenols (monophenols), with only one phenolic group, or di- (bi-), tri- and oligophenols, with two, three or several phenolic groups respectively. They can be found in plants and have an antioxidant activity. They are the most widely distributed class of plant secondary metabolites and several thousand different compounds have been identified.
