Nomenclature of Lignans and NenKgnans http //www.chem.qnuil.acuk/iupac/ lignan/... 

Last, but by no means least, our system of nomenclature and numbering can be applied not only to lignans and neolignans (i.e. Cg-Cs-dimers) but also to Cg-C3-oligomers without any change of concept. Several trimers (Fig. 7.3.8) and tetramers (Fig. 7.3.9) have already been isolated and it is easy to foresee that many more will be described in the future. 

Thus although based on biogenetic reasoning, supported at times by biomi-metic interconversions or even only by mechanistic speculations, we consider the nomenclature and numbering proposed in the present work to constitute the best classificatory criterion in the lignan-neolignan domain of secondary metabolites.
