 Title    Reversed Phase High Performance Liquid Chromatography of Essential Oils  
 Abstract    A reversed phase high performance liquid chromatographic procedure for the separation of essential oils is described. Applying water-acetonitrile elution systems on octyl and octadecyl-silane-bonded silica, complex mixtures o f sequiterpenes and oxygenated volatile constituents can be resolved, comparably to the quality o f gas chromatographic analysis. Photometrical detection at different wavelengths can be an important parameter in optimizing the separation of essential oil constituents. The application o f the described method is demonstrated with naturally occurring mixtures of terpenes from leaves of Cistus ladanifer.

 Title    Further Oxygenated Compounds in the Essential Oil of Cistus ladanifer L. (Cistaceae)  
 Abstract    Benzyl benzoate, cis-ocimenone and a new acetophenone derivative, 2-hydroxy-6-methyl aceto-phone, could be isolated by chromatographic methods from the essential oil o f Cistus ladanifer. Structural elucidation by NMR and MS are described. In addition pinocarvone, campholene alde­ hyde and tagetone were identified by their mass spectra.
