The separation of hop-derived compounds with several high-performance liquid chromatography techniques was studied. A system employing ion-exchange materials was developed which clearly resolves beta-, alpha-, and iso-alpha-acids in less than 2 h without gradient elution. Adsorption and partition columns can also separate the major groups of hop compounds. Reverse-phase partition chromatography is capable of resolving the cis- and trans-iso-alpha-acids.
