Abstract
Examination of the non-saponifiable constituents of the oxygenated fraction of hop essential oil has revealed the presence of 2-methyl butanol, linalool, methylnonyl ketone, methylundecyl ketone, geraniol, and the mono epoxides of caryophyllene and humulene as major constituents, together with three unidentified carbonyl compounds. Many other minor constituents are also present. Although geraniol is a major constituent of the non-saponifiable fraction, only traces of the free alcohol are present in the original oil.
