✦ Synopsis
The hop acids, the essential oils and the flavonoids of the hop (Humulus lupulus L.) varieties Saaz, Nugget and Wye Target have been studied for cultivar identification. Optimised reverse phase-high performance liquid chromatographic separations were carried out for the analysis of the hop acids and the flavonoids, whereas capillary gas chromatography was applied in order to characterize the essential oils. Appropriate handling of the quantitative chromatographic data by principal component analysis provided a clue to differentiate hop varieties.
