Part of the hard resin of hops is capable of forming an insoluble lead salt and is termed the α hard resin. The remainder is termed the β hard resin and consists partially of xanthohumol. Both fractions have been examined further by ion‐exchange chromatography, and hulupinic acid has been characterized as a component of the a hard resin. The latter increases as hops age as does the amount of hulupinic acid.
