Abstract

The gas chromatographic (GC) separation of a series of anomeric peracetylated alkyl- and arylglucosides on Apiezon L (2% and 3%) supported on Chromosorb W AW DMCS was studied. The 3% phase loading showed satisfactory separations of anomers of most of the glycosides. High-performance liquid chromatography, particularly in the reversed-phase mode with Radial-Pak C 18 , proved better for the separation not only of those compounds which could be separated by GC but also of those, such as p -biphenylyl- and cetyltetra-O-acetyl-D-glucosides, which presented difficulties in GC on Apiezon L.

Abstract

Barker and co-workers had described the C-1-H deformation bands in the ranges 844 ±8 cm−1 and 891 ±7 cm−1 as characteristic bands for the α and β anomers, respectively, of hexo- and pento-pyranoses and -pyranosides, and their derivatives. Later, Audichya and co-workers reported the presence of the 844 ±8-cm−1 band for both anomers of some aryl d -glucoside derivatives, making the applicability of the earlier findings doubtful. Examination by us of the i.r. spectra of some aryl glycoside derivatives suggested that the origin of the band at 844 ±8 cm−1 for the β anomers of the p-substituted-aryl glycoside derivatives studied by Audichya et al. could be a CH, out-of-plane deformation-mode of the substituted aromatic ring. Also, their further claim of a characteristic band in the region 961-957 cm−1 for α anomers is shown to be of little diagnostic value. The relative intensities of bands in the COC stretching region, 1100-1000 cm−1, and a band near 300 cm−1 in the COC deformation region, found only for the β anomers, are shown to be helpful in differentiating the anomers of some peracetylated alkyl and aryl glycosides.
