Secondary Ion Mass Spectra of Triterpenoidal Oligoglycoside
Mass spectrometric behavior of triterpenoidal oligoglycosides isolated from Panax ginseng C. A. Meyer have been investigated and the structures of four new triterpenoidal glycosides (MG-Rb,, MG-Rb2, MG-Rc, and MG-Rd) were determined using secondary ion mass spectrometry.
