Abstract

The steam-volatile constituents from several varieties of hops have been studied using conventional and capillary gas-chromatographic separation of constituents, followed by characterization of the constituents by one or more of the following physical methods: infra-red absorption spectra, mass spectra, and nuclear magnetic resonance spectra. Evidence was found for the identities of 40 compounds. These results have been used in a quantitative comparison by capillary gas chromatography of the steam-volatile constituents from five European hop varieties.
