Techniques for resveratrol silylation

Current separative strategies used for resveratrol determination from natural sources

“…It was also reported that a small amount of MeOH with BSTFA (around 1 : 3) enhanced the derivatization yield after comparing different silylation methods. 72 The electron ionization (EI) molecular ion was monitored at m/z 444 in SIM mode for quantitative determination, and ions at m/z 445 and 446 ( 30 Si-isotope containing species) are recorded as qualifiers. Of course direct injection (i.e.…”

Rapid determination of trans-resveratrol in vegetable oils using magnetic hydrophilic multi-walled carbon nanotubes as adsorbents followed by liquid chromatography–tandem mass spectrometry

“…The most commonly used technique is gas chromatography-mass spectrometry (GC-MS), which provides good sensitivity and specificity. To increase the thermal stability and volatility of trans-resveratrol, reaction with N,O-bis-(trimethylsilyl)-trifluoroacetamide (BSTFA) or acetic anhydride is required prior to analysis (Antonelli, Fabbri, & Lercker, 1996;Indyk, 1990;Montes, GarciaLopez, Rodriguez, & Cela, 2010;Tokusoglu et al, 2005). After the derivative is injected into the chromatographic system, high temperature (250-300°C) of ion sources might result in isomerization and degradation of the analyte.…”

Solid-phase microextraction—On-fibre derivatization with comprehensive two dimensional gas chromatography analysis oftrans-resveratrol in wine

“…Antonelli et al [8] reported an on-resin extraction method for resveratrol analysis, with derivatization carried out by adding excess silylating reagent to the final dried extracts.
