High Performance Liquid Chromatography Analysis of Colupulone Oxidation Products in Hops and in Beer. M. Verzele, N. Van de Velde, and C. Dewaele, Laboratory for Organic Chemistry, State University of Ghent, Krijgslaan, 281 (S.4), B-9000 GENT, Belgium. J. Am. Soc. Brew. Chem. 41:0057, 1983.
Tricyclo oxycolupulones, oxidation products of colupulone, occur in hops and in beer. This is shown by high performance liquid chromatography on a high-efficiency reversed-phase column. The concentration of these compounds in the beers analyzed varied between 30 and 200 µg/L.
