High-performance liquid chromatography coupled with fluorescence detection for the determination of trans-astringin in wine.
In this study a high-performance liquid chromatography (HPLC) method was developed for the determination of trans-astringin in wine using fluorescence detection. This is the first time the occurrence of trans-astringin has been reported in wine. The method allows analysis of both red and white wine samples with no prior treatment. The quantification threshold is 0.03 mg/l. Levels of trans-astringin in the French wines analyzed ranged from 0.09 mg/l to 0.29 mg/l. The reproducibility of the method was measured and the CV was less than 4.8% for both red and white wines.
