Multivariate optimization of supported liquid membrane extraction of biogenic amines from wine samples prior to liquid chromatography determination as dabsyl derivatives

Accumulation of Biogenic Amines in Wine: Role of Alcoholic and Malolactic Fermentation

“…Therefore, the elaboration of the appropriate derivatization procedures is still relevant, permitting chromatographic separation with satisfactory selectivity and accuracy. Among various reagents used for this purpose, the most popular were dabsyl chloride [32], dansyl chloride [33], benzyl chloride [34], 9-fluorenylmethoxycarbonyl chloride [35], o-phthaldialdehyde [36], fluorescein isothiocyanate [37], 1,2-naphthoquinone-4-sulfonate [38], 6-aminoquinolyl-N-hydroxysuccinimidyl carbamate [29] and diethyl ethoxy methylene malonate [39]. However, the use of a derivatization agent is often affected by restrictions or disadvantages, e.g., the reaction with dansyl-chloride is slow and not specific, o-phthaldialdehyde reacts only with primary amines, 1,2-naphthoquinone-4-sulphonate requires reaction conditions characterized by high pH and temperature and other reagents exhibit short detection wavelengths and low stability [20].…”

Structural effects on metal ion migration across polymer inclusion membranes: Dependence of transport profiles on nature of active plasticizer

“…4F), a drastic change in the distribution of the plasticizer in the mixture is observed as TBEP homogeneous profile changes to a non-uniform one. Although it was not possible to monitor CYANEX 272 distribution in such a mixture due to band overlapping, taking into account the strong chemical interaction observed for mixtures of similar organosphosphorous compounds [35], it is expected that an important amount of CYANEX 272 will be associated with TBEP. Through this assumption, percolation results make sense in a similar way as explained for NPOE and it is possible to rationalize why TBEP presents a percolation threshold value.…”

Influence of oenological practices on the formation of biogenic amines in quality red wines

“…Due to the complexity of wine, generally the analysis of BAs is accompanied by the use of techniques of pre or post column derivatisation, which permit a significant advance in the sensitivity on eliminating interferences. Among the different reagents used are: dansyl chloride (Csomos and Simonne, 2002;Anli et al, 2004;Caruso et al, 2002), o-phthalaldehyde (Herbert et al, 2001(Herbert et al, , 2004Gló ria et al, 1998;Iñ iguez-Crespo and Vá zquezLasa, 1994;Busto et al, 1997;Mafra et al, 1999;Vidal-Carou et al, 2003;Leitão et al, 2005;Moreno-Arribas et al, 2003;Martínez et al, 2000;Lavizzari et al, 2006;Del Prete et al, 2009), dabsyl chloride (Romero et al, 2000;Romero et al, 2002) and 6-aminoquinolyl-N-hydroxysuccinimidyl carbamate (Jimé nez- Moreno et al, 2003;Torrea and Ancín, 2001;Torrea and Ancín, 2002;Martínez et al, 2000).…”
