We describe a reversed-phase HPLC method that uses gradient elution and diode array
detection to quantitate eight biologically active phenolic constituents of wine: the cis and trans …

Using a solid-phase extraction followed by direct-injection gas chromatography-mass
spectrometry, the concentration of trans-resveratrol was measured in a representative selection of …

We have developed a normal-phase high-performance liquid chromatographic method to
measure the glucosides of cis- and trans-resveratrol as well as the free isomers in commercial …

Employing gradient elution HPLC with direct injection of 20 µL of sample and diode array
detection, the (+)-catechin and (-)-epicatechin concentrations were determined in >800 red …

A method to measure cis-resveratrol in wine, as well as frans-resveratrol simultaneously,
has been developed. One milliliter of wine is subjected to solid phase extraction on a Cis …

We have developed a novelmethod to measure the concentration of the trihydroxystilbene
trans-resveratrol suitable for the analysis of wine and other biological materials. Solid-phase …

We have developed a GC/MS method to simultaneously measure the concentrations of 15
biologically active phenolic components of wine: vanillic acid, gentisic acid, m- and p-…

Using an HPLC method with diode array detection, we have measured the concentrations
of flavan 3-ols (catechin and epicatechin), trihydroxystilbenes (the cis and trans isomers of …

Using analytical methods based upon high performance liquid chromatography, the quercetin
and p-coumaric acid concentrations were analyzed in 872 and 547 commercial red wines, …

A gas chromatographic-mass spectrometric method has been developed and validated for
the analysis of cis- and trans-resveratrol simultaneously in matrices such as wine and grape …
