PROGRESS in instrumental methods of analysis during the past 10 years, particularly in the new field of gas chromatography, has provided the chemist with powerful tools for the separation and identification of complex mixtures. Nevertheless, it is often advantageous to fractionate the mixture prior to gas chromatography analysis in order to simplify ...

EVALUATION OF HOPS V. THE ESSENTIAL OIL OF HOPS
Journal of the Institute of Brewing, 1957The aromatic constituents of hops have been analysed by gas chromatography. The essential oil comprises a mixture of hydrocarbons and of oxygenated materials, these two main fractions being readily separated by chromatography on silica gel. The hydrocarbons, which account for 70–80% of the total oil, comprise mainly myrcene, caryophyliene and humulene ...

Journal of the Institute of Brewing, 1966
Methyl geranate has been identified with some certainty in oil from Bullion hops by comparison of infra-red absorption and mass spectral patterns with those of authentic methyl geranate. It has also been found that methyl geranate varies considerably in concentration in oils from different varieties, being almost completely absent from some varieties.

THE STABILITY OF HOP OILS IN LIQUID CARBON DIOXIDE EXTRACTS OF HOPS
Journal of the Institute of Brewing, 1983Portions of extracts obtained by treating three varieties of hops with liquid carbon dioxide were stored in the cold and at ambient temperature for 18 months. During this period the composition of nop oils remained stable, except for the formation of two terpene methyl sulphides in extracts from all three varieties.
