Phlorizin Phlorizin Phlorizin (also referred to as phloridzin; chemical name phloretin-2'-β--glucopyranoside) is a glucoside of phloretin, a dihydrochalcone, a family of bicyclic flavonoids, which in turn is a subgroup in the diverse phenylpropanoid synthesis pathway in plants. Phlorizin is found primarily in unripe "Malus" (apple), root bark of apple, trace amounts have been found in strawberry. 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 phloridzin. Phloridzin is a phytochemical that belongs to the class

"dasycalyx" Pehr Kalm, who was one of the twelve men whom Linnaeus called his apostles and sent forth to explore the vegetable world, wrote from America: Malus coronaria Malus coronaria, also known by the names sweet crabapple or garland crab, is a North American species of "Malus" (crabapple). It grows primarily in the Great Lakes Region and in the Ohio Valley, with outlying populations as far away as Alabama, eastern Kansas, Long Island, and Ontario. "Malus coronaria" often is
