Abstract
In the present study, the composition of the hop strobilus extract by using different extraction methods under different solvent conditions was analysed and compared. Several separation methods were applied to obtaining detailed information about the hop extract: capillary zone electrophoresis (CZE), high-performance liquid chromatography-mass-spectrometry (HPLC-MS/MS) and gas chromatography–mass-spectrometry (GC–MS). The electropherograms of different extracts varied dramatically. The oxidation reaction of the hop strobilus extract was examined.
