Brit.

/flɒˈrɛtɪk/, U.S.

/flɔˈrɛdɪk/

Origin: Formed within English, by derivation; modelled on a French lexical item. Etymons: phloretin n., -ic suffix.

Etymology: < phloret- (in phloretin n.) + -ic suffix, after French phlorétique (in acide phlorétique: J.-S. Stas 1838, in Ann. de chim. et de physique 69 386). Compare German Phloretinsäure (1839).

Chemistry.

1. phloretic acid n. an acid, (HOC₆H₄)CH₂CH₂COOH, resulting (together with phloroglucinol) from the decomposition of phloretin.

ΚΠ

1840 Penny Cycl. XVIII. 98/2 Phlorizin is by various processes, described by M. Stass, converted into phlorizein, phloretin, and phloretic acid.

1959 Science 10 July 104/3 A combination of overlapping moieties (phloretic acid and phlorpropiophenone) was used.

1984 Xenobiotica 14 918 Synthesis of the glycine conjugate of phloretic acid was difficult due to the lability of the amide bond.

†2. phloretic ether n. an ester of phloretic acid. Obsolete.
