Phloretin is a dihydrochalcone, a type of natural phenols. It can be found in apple tree leaves[1] and the Manchurian apricot.[2]

Pharmacology

Phloretin inhibits the active transport of glucose into cells by SGLT1 and SGLT2, though the inhibition is weaker than by its glycoside phlorizin.[3] Orally consumed phlorizin is nearly entirely converted into phloretin by hydrolytic enzymes in the small intestine.[4][5] An important effect of this is the inhibition of glucose absorption by the small intestine[5] and the inhibition of renal glucose reabsorption.[4] Phloretin also inhibits a variety of urea transporters.[6][7] It induces urea loss and diuresis when coupled with high protein diets.

Phloretin has been found to inhibit GLUT2.

Metabolism

Phloretin hydrolase uses phloretin and water to produce phloretate and phloroglucinol.
