Abstract
Microemulsion electrokinetic chromatography has been applied to the an alysis of hop acids in extracts of different hop cultivars. With this new analytical method, the 6 main hop bitter acids are completely sepa rated. within 10 minutes. Quantitative analyses of extracts from Saaz, Nugget and Wye Target cultivars have been compared to those obtained with reversed-phase high-performance liquid chromatography. The cohumu lons and colupulone ratios are in good agreement. Microemulsion electr okinetic chromatography however is much faster and provides, in additi on, data for the adhumulone and adlupulone ratios.
