Phloretin occurs in the form of two distinct glucosides, phloridzin and glycyphyllin, which are found in the root-bark of the apple, cherry, and plum-tree, and in the leaves of Smilax glycyphylla respectively (cf. Rennie, Jour. Chem. Soc., 1887, 634); whilst by catalytic hydrogenation of naringenin, in alcoholic solution with palladous chloride and hydrogen, Franck (Beitr. Phys., 1, 179; cf. Chem. Centrbt., 1914, ii., 253) obtained a dihydro-naringenin which he considered to be identical with phloretin.
