phlo·rid·zin

(flō-rid'zin),
A dihydrochalcone occurring in many parts of the apple tree; used experimentally to produce glycosuria in animals.
Synonym(s): phlorizin

phlorhizin

, phlorizin, phloridzin (flōr′ĭ-zĭn, flŏ-rīz′ĭn) (flōr′ĭd-zĭn, flŏ-rid′zĭn) [Gr. phloios, phloos, bark + rhizo- + -in]
A glycoside present in the bark of some fruit trees. It is a powerful inhibitor of sugar transport in some animals.

rebaudiana natural products exert an inhibitory effect on monosaccharide transport in the intact rat liver, as is the case for phlorizin and phloretin in the renal tubules (Ishii et al., 1987).
The kinetic parameters (Kii and Kis) of the intact NE G-6-Pase for the phlorizin inhibition using glucose-6-phosphate (G-6-P) and M-6-P as substrates, were very similar.
Enzymes involved in this first reaction are lactase phlorizin hydrolase (a beta-glucosidase) and/or gut microbiota-derived betaglucosidase, depending on the nature of the glycoside [2, 6].
HPLC analysis indicated that the major polyphenols in the SFE extracts consisted of chlorogenic acid, caffeic acid, syrigin, procyanidin B2, (-)-epicatechin, cinnamic acid, coumaric acid, phlorizin and quercetin, of which procyanidin B2 had the highest content of 231.77 mg/kg.
Orally consumed phlorizin is mainly converted into phloretin by hydrolytic enzymes in the small intestine, and inhibits glucose absorption by the small intestine and renal glucose reabsorption as a glucose transporter 2 inhibitor (Idris and Donnelly 2009).
