| Abstract: | Hop oil was investigated by gas chromatography coupled to a mass spectrometer. Almost all substances were obtained by preparative gas chromatography in amounts sufficient for N.M.R. spectral identification. Hop oil was separated into hydrocarbon- acid- alcohol- and ketone-containing fractions using adsorption chromatography, saponification, alkaline extraction and extraction with Girard T reagent. Fifty-three substances were identified of which sixteen have not been recorded previously as occurring in hop oil. |
