Gas‐liquid partition chromatography of the mixture of fatty acids obtained by oxidizing the α‐soft resin of hops constitutes a rapid and accurate method for the determination of the cohumulone, humulone and adhumulone contents of the resin. The proportions of the corresponding colupulone, lupulone and adlupulone in the “β‐acids” may be determined similarly or, alternatively, by the use of liquid‐liquid partition chromatography.
