摘要：

Gas chromatography (CC) data (linear retention indices and relative areas) and mass spectra (most representative m/z fragments) of 12 reducing trisaccharides as trimethylsilyl oximes (TMSO) and four non-reducing as trimethylsilyl (TMS) ethers have been described for the first time and related to their structural features. Some trends have been observed: earlier elution of non-reducing compounds and fructotrioses; aldotrioses hearing the reducing end with link in position 6 showing the highest retention. Abundance of several fragment tons and their ratios were useful for trisaccharide characterization; some of these features seem to be useful for the characterization of new trisaccharides.
