Abstract

This thesis comprises besides the characterisation of new oligomeric flavenoids from the core wood of the indigeneous Colophosphermum mopane, an investigation into the C/sub 4/-functionalisation of flavan-3-ol analogues. The first peltogynoid biflavenoid and prototypes of a new series C-ring isomerised condensed tannins, namely the phlobatannins, were isolated. Besides /sup 1/H- nmr-parameters for structure analysis, the natural phlobatannins were characterised and the unique ring isomerisation was investigated.
