“…However, owing to polarity, hydrophilicity and low volatility, carbohydrates have to be converted into volatile and stable derivatives, i.e. acetate or trimethylsilane (TMS) derivatives (Adam and Jennings, 1975; Bartolozzi et al ., 1997; Guignard et al ., 2005; Li and Schuhmann 1980; Low and Sporns, 1988; Molnár‐Perl and Horváth, 1997; Molnár‐Perl and Szakács‐Pinter, 1985; Molnár‐Perl et al ., 1984, 1990; Morita and Montgomery, 1978; Rojas‐Escudero et al ., 2004; Schäffler and Du Boil, 1981; Silva and Ferraz, 2004; Toba and Adachi, 1977) before GC analysis. Generally, silylation is the most common and versatile method for the derivatisation of organic compounds containing active hydrogen atoms and resulting in products with reduced polarity (fewer dipole–dipole interactions), enhanced volatility and increased thermal and catalytic stability necessary for optimal sensitivity and resolution (Halket and Zaikin, 2003).…”

SummaryThis paper describes the separation and quantitation of mono-di-and trisaccharides in model solutions. Optimized conditions for identification and determination of common sugar constituents in several natural matrices by GC-MS, from one solution by one injection, are given. Applying a 52 min temperature program to a 30 m capillary column and taking advantage of the stable ratios ofthe syn-and anti oximes eluting either alone or together with one or two other anomers: provides the basis of calculation for co-eluting compounds. Saccharides (5-200 ng), such as fructose, glucose, sucrose, trehalose, cellobiose, maltose, turanose, gentiobiose, palatinose, melibiose, isomaltose, erlose, raffinose, melezitose, maltotriose, panose and isomaltotriose, in the presence of each other in various ratios, have been measured as silyloxime compounds with a reproducibility of < 5 R.S.D. %. The possibility of measuring all these saccharides as their TMS methoximes is also presented.

Rapid methods of analysis for the simultaneous determination of acids and sugars in fruits and vegetables using trimethylsilylation and gas chromatography are reported. The methods have been shown to be generally applicable, rapid, simple and cheap. Typical applications are shown involving the determination of a range of organic acids and sugars in carrot, potato, cucumber, tomato, apple, pear, grape, strawberry and citrus fruits.
