Description	A rapid method for qualitative and quantitative analysis of 17 phenolic acids (gallic acid, 3,5-dihydroxybenzoic acid, protocatechuic acid, chlorogenic acid, gentisic acid, 4-hydroxybenzoic acid, caffeic acid, vanillic acid, syringic acid, 3-hydroxybenzoic acid, 4-coumaric acid, sinapic acid, ferulic acid, 3-coumaric acid, 2-coumaric acid, salicylic acid and trans-cinnamic acid) in different beverages was developed using ultra performance liquid chromatography (UPLC) coupled with tandem mass spectrometry (MS/MS). The analytes were detected in multiple reaction monitoring (MRM) mode and quantified using internal standards of deuterium-labelled 4-hydroxybenzoic (2,3,5,6-D4) and salicylic (3,4,5,6-D4) acids. Limits of detection (LODs) ranged from 0.15 to 15 pmol and the response was linear to 1000 pmol injected. Mean method precision of 4.4 RSD% (range, 2.0–9.1%) was obtained, and a mean accuracy (bias) of 1.1% (range, 14.5 to 17.5%). The applicability of this analytical approach was confirmed by the ...

(en) Byla vyvinuta rapidní metoda pro analýzu 17 fenolických kyselin v nápojích pomocí ultraúčinné kapalinové chromatografie (UPLC) spojené s tandemovou hmotnostní spektrometrií (MS/MS). Analyty byly detekovány v MRM módu a jeich kvantifikace byla založena na interních deuteriem značených standardech kyselin 4-hydroxybenzoové (2,3,5,6-D4) a salicylové (3,4,5,6-D4). Limity detekce (LODs) se pohybovaly v rozmezí 0,15 – 15 pmol/nástřik a odezva byla lineární do 1000 pmol/nástřik. Průměrná přesnost stanovení byla 4,4 RSD% (rozsah 2,0 – 9,1%) a průměrná správnost 1,1 % (rozsah -14,5 – 17.5%). Použitelnost vyvinuté metody byla potvrzena analýzou reálných vzorků bílého vína, grapefruitového džusu a zeleného čaje. Dvanáct fenolických kyselin bylo stanoveno v analyzovaných nápojích v koncentracích od 40,8 do 9046 μg L-1 a výsledky byly srovnány s daty z předchozích studií. (cs)
