Abstract:

This work is focused on the determination of proline in 24 Czech mead samples using reversed-phase high performance liquid chromatography (RP-HPLC) coupled with fluorescence detector (operating at excitation wavelength λex = 264 nm and emission wavelength λem = 497 nm). Sample pre-treatment including solid phase extraction of mead by Strata SCX SPE column and a derivatization of the extract acquired by dansyl chloride was performed and thoroughly optimised. Derivative of proline was separated using Ascentis Express C18 column (150 × 3 mm, 2.7 μm) in the combination with binary mobile phases that had consisted of 0.1% TEA (pH 3.0) and 100% acetonitrile. The method proposed could be used for evaluation of mead quality and its authenticity.
