General description
Vescalagin, an ester derivative of open-chain D-glucose, is a C-glycosidic ellagitannin widely present as a principal phenolic metabolite in various plant species.
Application
Vescalagin may be used as an analytical standard for the determination of the analyte in oak tannins, chestnut bark samples (Castanea sativa Mill.), wine, fruit samples, and vegetable tanning agents by liquid chromatography (LC) based techniques.

Commercial vegetable tanning agents that are derived from plants and consist of condensed or hydrolyzable tannins were analyzed by electrospray ionization-tandem mass spectrometry (ESI-MS/MS) to identify their major constituents and to study their collision-induced dissociation. In the condensed tannin wattle

A new method for the analysis of ellagitannins observed in oak-aged wine is proposed, exhibiting interesting advantages with regard to previously reported analytical methods. The necessary extraction of ellagitannins from wine was simplified to a single step of solid phase
