It is generally known that specimens of Carex species plants are resistant to insects and contain a variety of stilbene compounds. Some stilbene oligomers obtained from four kinds of Carex plants were analyzed by mass spectrometry. The electron impact mass spectra, secondary ionization mass spectra, and B/E linked scan spectra were measured to investigate their fragmentations.
Key words: Stilbene oligomer, Structure determination, EIMS spectra, SIMS spectra, B/E linked scan spectra
