Popis: Proceeding with a similar way as previous works, we characterised the presence of lignins in wines. This natural poly - mer was chosen as biomarker. It's a remarkably stable in time and typical wood component. We used the thioacidolysis reaction with ethanethiol and boron trifluoroetherate as reagents, to obtain some characteristic phenylpropane units from the lignin poly - mer. Identification was performed by mass spectrometry coupled with gas chromatography (GPG/SM) of thioacidolysis products in trimethylsili lated form. The aim of this study is the demonstration of wine aging in barrel before bottling.
