Characterization of Grape Cane Stilbenoids and Their Photo-Degradation Products by HPLC-DAD Coupled With Trapped Ion Mobility Spectrometry and High-Resolution Tandem Mass Spectrometry. [PDF]

Rapid Commun Mass Spectrom
ABSTRACT Rationale Bioactive (E)‐stilbenoids in vine extracts are prone to light‐induced transformation into the respective (Z)‐isomers and further degradation products, often resulting in a loss of bioactivity. We sought to study stilbenoid degradation beyond that of the well‐researched resveratrol due to the high diversity of stilbenoids in nature ...
