Tabernaemontana cell cultures have also been studied as a source for dimeric indole alkaloids (for review, see Ref. 730). Although the plants produce considerable amounts of dimers, so far only small amounts of conodurine-type dimers and monogagaine could be found in callus cultures of T. elegans (731). Cell suspension cultures of this species produced various monomers, whereas only traces of yet unidentified dimers could be found (732).
