“…However, mass spectra of tetrasaccharides are more difficult to interpret because of the lower number of available standards and the accumulation of identical fragments coming from four sugar rings in the same molecule (Table 1). Peaks 28-34 (except for peak 33) were clearly derivatives of sucrose, as shown by the presence of m/z fragments 437 and 451 (Kamerling et al, 1972). Nystose was identified as peak 28 by comparison with the commercial standard.…”

“…1 were identified as raffinose and 6-kestose by comparison with data from the corresponding standards and from the literature (Kamerling, Vliegenthart, Vink, & de Ridder, 1972;Sanz et al, 2004). Peak 3 was an unresolved mixture of 1-kestose and neo-kestose, as shown by the different m/z ratio 437/ 451 obtained in the fronting and tailing part of the peak (>1 and <1, respectively) (Kamerling et al, 1972).…”

Gas chromatographic–mass spectrometric characterisation of tri- and tetrasaccharides in honey

et al. 2010

a b s t r a c tA GC-MS method has been used to characterize tri-and tetrasaccharides in honey after their derivatization into trimethylsilyloxime derivatives. Based on retention data and mass spectra, a total of 25 trisaccharides were characterized; 12 being unequivocally identified using standards and two of them detected for the first time in honey. Erlose and panose were the major trisaccharides in the 12 honeys under analysis, their concentrations ranging 30-1214 mg 100 g À1 of honey and 17-863 mg 100 g À1 of honey, respectively. The GC-MS method also allowed the analysis of tetrasaccharides. Besides nystose, another nine tetrasaccharides were characterized; six of them were sucrose derivatives. Tetrasaccharides were present in concentrations lower than 230 mg 100 g À1 of honey.

This review describes the mass spectral fragmentation of trimethylsilyl (TMS) and related alkylsilyl derivatives used for preparing samples for analysis, mainly by combined gas chromatography and mass spectrometry (GC/MS). The review is divided into three sections. The first section is concerned with the TMS derivatives themselves and describes fragmentation of derivatized alcohols, thiols, amines, ketones, carboxylic acids and bifunctional compounds such as hydroxy‐ and amino‐acids, halo acids and hydroxy ethers. More complex compounds such as glycerides, sphingolipids, carbohydrates, organic phosphates, phosphonates, steroids, vitamin D, cannabinoids, and prostaglandins are discussed next. The second section describes intermolecular reactions of siliconium ions such as the TMS cation and the third section discusses other alkylsilyl derivatives. Among these latter compounds are di‐ and trialkyl‐silyl derivatives, various substituted‐alkyldimethylsilyl derivatives such as the tert‐butyldimethylsilyl ethers, cyclic silyl derivatives, alkoxysilyl derivatives, and 3‐pyridylmethyldimethylsilyl esters used for double bond location in fatty acid spectra. © 2019 Wiley Periodicals, Inc.

“…The derivatization procedure described previously gives for these compounds single peaks of their octakis-TMS ethers, whose corresponding mass spectra have already been described [12,13]. They showed characteristic ions at m/z 435,437 and 451.…”

SummaryTwenty-three disaccharides have been analysed by GC-MS as their O-trimethylsilyl oximes. The relationships bel',,veen their mass spectral fragmentation and their structural characteristics have been studied in order to use GC-MS information for quahtative purposes. The presence of some structural features, such as the 1 -2 or 1 -6 linkages, can be estimated from the relative intensity of fragment ions. The method has been applied to the determination of the components present in the disaccharide fraction obtained from lactose treatment with 13-galactosidase from K. fragilis.
