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
Fruit tree Fruit tree A fruit tree is a tree which bears fruit that is consumed or used by humans and some animals — all trees that are flowering plants produce fruit, which are the ripened ovaries of flowers containing one or more seeds. In horticultural usage, the term 'fruit tree' is limited to those that provide fruit for human food.
