Forms: 1800s– phlorhizin, 1800s– phloridzin Brit.

/flɒˈrɪdzɪn/, U.S.

/flɔˈrɪdzɪn/, 1800s– phloridzine, 1800s– phlorizin, 1800s– phlorizine, 1900s– phlorrhizin.

Origin: Either (i) a borrowing from French. Or (ii) a borrowing from German. Etymons: French phloridzin; German Phloridzin.

Etymology: < French phloridzin (L. de Koninck and J.-S. Stas 1835, in Bull. de l'Acad. Royale des Sci. et Belles-Lettres de Bruxelles 2 5; also as phloridzine , phlorizine , phlorhizine ) or its etymon German Phloridzin (L. de Koninck 1835, in Ann. der Pharm. 15 76; Phlorrhizin is suggested there by the editor as the proper form of the word) < ancient Greek ϕλοιός bark (see phloem n.) + ῥίζα root (see rhizo- comb. form) + German -in -in suffix¹.

Chemistry.

A crystalline compound, C₂₁H₂₄O₁₀, which is a glucoside of phloretin, occurs widely in apple and other fruit trees, and acts biochemically as an uncoupler.
