Abstract
Nowadays, the techniques for the analysis of glycosidic precursors in grapes involve
changes in the glycoside structure or it is necessary the use of very expensive analytical techniques.
In this study, we describe for the first time an approach to analyse intact glycosidic aroma precursors
in grapes by high-performance liquid chromatography with a diode array detector (HPLC-DAD),
a simple and cheap analytical technique that could be used in wineries. Briefly, the skin of Muscat
of Alexandria grapes was extracted using a microwave and purified using solid-phase extraction
combining Oasis MCX and LiChrolut EN cartridges. In total, 20 compounds were selected by
HPLC-DAD at 195 nm and taking as a reference the spectrum of phenyl
