Biosynthesis. Part XIX. Concerning the biosynthesis of (–)-camphor and (–)-borneol in Salvia officinalis

Salvia officinalis is selected after extractions and tracer experiments as a suitable species for biosynthetic work on bicyclic monoterpenes. [2-14C]Geraniol is synthesised and is shown to be incorporated specifically by S. officinalis plants into camphor and borneol by unambiguous degradation of the isolated terpenes. Comment is made on results which emphasise the dangers of reliance on g.l.c. purification of terpenes for radio-tracer work.
