Abstract A supercritical fluid chromatographic method combined with Fourier-transform infrared spectroscopy detection (SFC–FTIR) was developed for determination of varietal differences in essential oil constituents in hops (Humulus lupulus). Infrared spectra (IR) of the major constituents of essential oil of hops were taken as films deposited on AgCl discs and compared with those obtained after chromatographic separation in the IR flow-cell with supercritical carbon dioxide (scCO2). Spectra from AgCl discs were comparable to those in scCO2, but in scCO2 most of the bands appeared approximately 8–10 cm−1 to higher wave numbers. Open-tubular SFC–FTIR analysis of the essential oil of 4 different hop varieties was performed. The SFC–FTIR chromatograms showed differences in the location and relative intensity of the peaks depending on the variety, which was further confirmed by consideration of their FTIR spectra.

Abstract The essential oil of strobiles from Humulus lupulus L. var. neomexicanus Nels. & Cockerell, grown in the semi-arid climate of Central Colorado, was isolated by steam distillation. A characteristic seasonal dependence of oil production was observed over two vegetation periods. - The main components of the essential oil were identified structurally by means of GC and GC-MS analysis. About 40 different compounds, including monoterpenoic hydrocarbons and alcohols, ketones, methylesters of saturated and unsaturated carboxylic acids were detected. Other sub­ stances were esters of short chain acids with monoterpene alcohols, plus sesquiterpene hydro­carbons.
