Phloridzin, a dihydrochalcone, is found in all parts of the apple tree (Malus sp.) except the mature fruit. It is the predominant phenolic compound in leaves with a dry weight of 18% (Petkovsek et al., 2009).
At Aphios®, Phloridzin is extracted from apple wood using segmentation chromatography.
Dietary consumption of Phloridzin has been shown to reduce blood glucose levels (Masumoto et al., 2009). Phloridzin is shown to induce experimental glycosuria by blocking the reabsorption of glucose from the kidney (Shapiro, 1946). The anti-diabetic action is through the competitive inhibition of the sodium-dependent blood transporters (SGLT1 and SGLT2) of metabolites such as glucose (Ehrenkranz et al., 2005).
Additionally, Phloridzin activates a cascade of enzymes, including tyrosinase, by blocking the activity of protein kinase C (Shoji et al., 1997). As a result, it is involved in inhibiting the growth of tumor cells (Shoji et al., 1997) and provides increased protection against ultraviolet radiation through the activation of melanogenesis (Jung et al., 2009).
