Attempts to separate (-)-α-thujone, (+)-β-thujone epimers from camphor enantiomers by enantioselective HPLC with polarimetric detection.

J. Sep. Sci. 36(5) , 832-9, (2013)

In a first step, 26 chiral stationary phases (CSPs) have been screened for the separation of (-)-α-thujone, (+)-β-thujone epimers and camphor enantiomers by LC. The separations were monitored by a pol...

Long-term stability of thujone, fenchone, and pinocamphone in vintage preban absinthe.
