Abstract
Distilled spirits contain numerous phenolic constituents which are extracted, in part, from the wood cask during maturation. Such compounds may provide information on authenticity and quality of the products. Analyses have so far focused on the determination of the volatile constituents by GC, including GC-MS. Few HPLC methods for whisky analysis have been published. However, they are time-consuming [1] or afford only limited resolution [2]. This prompted us to explore the potential of Ultra High Performance Liquid Chromatography (UPLC) for the analysis of whiskies. UPLC is a recent development of HPLC relying on small size particles, which increase significantly resolution and considerably reduce separation time [3]. Using a HSS T3 column (2.1×100mm; 1.8µm, Waters) and a gradient of methanol in water containing 0.1% TFA over 60min, more than 15 compounds, including phenolic acids, aldehydes, phenols and furans could be identified from their chromatographic and UV properties, and by comparison with authentic samples. In addition, several lignans were identified after semipreparative isolation and 1H NMR measurement using a 1mm TXI microprobe (Bruker) [4].
