Molecular Composition Study of Mumijo from Different Geographic Areas Using Size-Exclusion Chromatography, NMR Spectroscopy, and High-Resolution Mass-Spectrometry

摘要

Four mumijo samples originated from different mountain ranges were studied using size-exclusion chromatography (SEC),Fourier-transform ion cyclotron resonance mass spectrometry (FTICR MS),1H and 13C NMR spectroscopy.All the used analytical techniques demonstrated that the mumijo samples studied consist of a "high-molecular" fulvic-like and a low-molecular components.The second component is shown using FTICR MS and NMR methods to be predominantly a range of vegetative and animal metabolites.
