REMARKS - In contrast to bog peat (Spectrum F.14), sphagnum peat exhibits an almost strictly polysaccharide pattern with strong peaks at m/z 114 and 128 indicating the presence of sugar residues other than hexose, e.g. pentose and deoxyhexose. The absence of a typical lignin pattern such as in bog peat is explained by the lack of true lignins in Sphagnum moss (Spectrum E.16). The only lignin-like constituent of Sphagnum moss, sphagnol (ref. 85), apparently gives rise to the nonmethoxylated (a 1kyl)phenol series at m/z 94, 108, 120 ana 134. Also note the absence of pyrolytic methane (m/z 16).
