Abstract

The simultaneous determination of organic acids (succinic, malic, pimelic, tartaric, shikimic, citric, quinic, cafeeic and chlorogenic acids), sorbitol and sugars (arabinose, rhamnose, fructose, galactose, glucose, sucrose, maltose and raffinose) as trimethylsilyl (TMS)-oxime and TMS derivatives in a single solution has been developed. The optimum conditions for the simultaneous derivatization and the rapid quantitative evaluation of the nineteen compounds by capillary gas-liquid chromatography are reported in this paper. Reproducibility data reveal that {slanted equal to or greater-than}0.02 μg of acids in the presence of {slanted equal to or less-than}12 μg of sugars can be determined with a relative standard error (R.S.E.) of {slanted equal to or less-than}11.2%, whereas the m ain constituents are determined with an R.S.E. of {slanted equal to or less-than}3.6%.
