Online Energy-Resolved Mass Spectrometry Enables Differentiation of Glycosylation Sites and Sugar Moieties Supporting More Accurate Identification of Ginsenoside Isomers
{{output}}
Structural characterization of natural saponins is highly challenging by tandem mass spectrometry, lacking evidence for differentiating multiple glycosylation sites and diverse sugar moieties. Optimal collision energy (OCE) in collision-induced dissociation ha... ...
