COMPARATIVE FTIR AND C-13 CP MAS NMR SPECTROSCOPIC INVESTIGATIONS ON SPOROPOLLENIN OF DIFFERENT SYSTEMATIC ORIGINS/

Comparative phytochemical investigations were carried out on sporopoll enins of the following plant species: Bryophyta-Reboulia hemisphaerica and Polytrichum strictum; Pteridophyta-Equisetum arvense, Selaginella selaginoides micro- and megaspores; Gymnospermae-Cycas circinalis; An giospermae-Typha angustifolia and Tulipa cv. ''Apeldoorn''. Although t he range of the analyses included species from the Bryophyta to the An giospermae, fundamental correspondences could be detected in the C-13 NMR and FTIR spectra concerning the occurrence of aliphatics, aromatic s, ether and carbonyl/carboxylic functions in varying degrees. While t he amount of aliphatics strongly dominated in the molecular structure of all other sporopollenins investigated here, it was found in sporopo llenin of Equisetum arvense in a much lower extent. Despite the differ ent morphology of Selaginella selaginoides micro- and megaspores, thei r sporopollenin spectra were nearly identical.
