Gc. Galletti et al., PYROLYSIS-GAS CHROMATOGRAPHY ION-TRAP MASS-SPECTROMETRY OF THE TOOTH BRUSH TREE (SALVADORA-PERSICA L), Rapid communications in mass spectrometry, 7(7), 1993, pp. 651-655
Chemical characterization of 'tooth brush' tree (Salvadora persica L.)
sticks was carried out using a pyrolysis/gas chromatograph coupled to
an ion-trap detector mass spectrometer. Electron impact and chemical
ionization mass spectra, along with chromatographic profiles obtained
by both flame ionization and nitrogen/phosphorous detectors,enabled th
e structure of some eighty pyrolysis fragments to be proposed. These w
ere mainly lignin and polysaccharide derivatives of phenolic and furan
ic natures, respectively. However, compared with the pyrograms of othe
r well-studied lignocellulosic materials, S. persica showed several un
ique nitrogen-containing compounds, some of which were tentatively ide
ntified as pyrrolidine, pyrrole and piperidine derivatives on the basi
s of their mass spectra and chromatographic elution order.
