NMR Study of the Phenolic Component Composition of Plant Metabolomes

Dimethylsulfoxide (DMSO) extracts of medicinal plants were studied by PMR spectroscopy in order to assess the possibility of using this method for the identification and quantitative determination of polyphenolic compounds (flavonoids, tannins, etc.). Dependences of polyphenol-hydroxyl proton chemical shifts on the nature and position of aromatic substituents were studied.
