Phlorizin is found primarily in unripe Malus [2] root bark of apple, [3] and trace amounts have been found in strawberry. [4] In Malus, it is most abundant in vegetative tissues (such as leaves and bark) and seeds. Closely related species, such as pear (Pyrus communis), cherry, and other fruit trees in the Rosaceae do not contain phlorizin. [5]
The main source of polyphenols is dietary, since they are found in a wide array of phytochemical-bearing foods.For example, honey; most legumes; fruits such as apples, blackberries, blueberries, cantaloupe, pomegranate, cherries, cranberries, grapes, pears, plums, raspberries, aronia berries, and strawberries (berries in general have high polyphenol content [5]) and vegetables such as broccoli ...

In the European Union, two health claims were authorized between 2012 and 2015: 1) flavanols in cocoa solids at doses exceeding 200 mg per day may contribute to maintenance of vascular elasticity and normal blood flow; [62] [63] 2) olive oil polyphenols (5 mg of hydroxytyrosol and its derivatives (e.g. oleuropein complex and tyrosol) may ...
The phenolic unit can be found dimerized or further polymerized, creating a new class of polyphenol. For example, ellagic acid is a dimer of gallic acid and forms the class of ellagitannins, or a catechin and a gallocatechin can combine to form the red compound theaflavin , a process that also results in the large class of brown thearubigins in ...
“Daily consumption of moderate amounts (defined in this review as two to three cups or 300 mg/day) has been associated with several health benefits, such as better cognitive function and reduced ...
