It belongs to the group of dihydrochalcones, a type of flavonoids. ==Occurrence== Phlorizin, or phloridzin is a naturally occurring flavonoid produced in some plants. It is found primarily in ''Malus'' (apple) species although trace amounts exist in other species. In ''Malus'' it is most abundant in vegetative tissues (leaves, bark, etc...) and seeds. Closely related species, such as pear (''Pyrus communis''), cherry and other fruit trees in the ''Rosaceae'' do not contain phloridzin.〔Gosch, C., Halbwirth, H., & Stich, K. (2010). Phloridzin: biosynthesis, distribution and physiological relevance in plants. ''Phytochemistry'', ''71''(8), 838–843.〕 Trace amounts have been reported in strawberry 〔Hilt, P., Schieber, A., Yildirim, C., Arnold, G., Klaiber, I., Conrad, J., … Carle, R. (2003). Detection of phloridzin in strawberries (Fragaria x ananassa Duch.) by HPLC-PDA-MS/MS and NMR spectroscopy. ''Journal of Agricultural and Food Chemistry'', ''51''(10), 2896–2899.〕 and it is responsible for the petal color in ''Dianthus caryophyllus''.〔(Isosalipurposide on PubChem )〕 Phloridzin, a phytocemical belongs to a class of polyphenols. It may be present with other polyphenols such as quercetin, catechin, epicatechin, procynidins, rutin etc. These polyhydroxy compounds have been proved to be potent antioxidants.〔http://www.chemkind.com/chemicals-p_3685039_phloridzin.htm〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「phlorizin」の詳細全文を読む スポンサード リンク
