remarks - This spectrum also shows a typical polysaccharide pattern with only minor indications for the presence of other plant materials. However, this polysaccharide pattern appears to be somewhat more complex than that of cotton (Spectrum E.l) and flax (Spectrum E.2). For instance, the relatively high peak intensities at m/z 114 and 128 may well be derived from hemicellulose constituents (compare with the relatively high intensities of m/z 114 and 128 in the spectra of wood (Spectrum E.ll) and cork (Spectrum E.12).
