The phloroglucin ester of paraoxyhydratropic acid, found in the leaves of apple trees.
A bitter white crystalline compound gotten by the decomposition of phlorizin, and formerly familiar with a point instead for quinine.
A crystalline compound, C15H14O5, created by hydrolyzing phlorizin with dilute acids. It melts at 253–255° C., and it is turned into phloretic acid and phloroglucinol by boiling with caustic potash. It's a febrifuge.
