โœฆ Synopsis

In the course of a study of the sesquiterpenes of the leaf oil of Alaska Cedar (Chamaecy-Paris nootkatensis)

1 we encountered a levorotatory calamenene which was clearly a mixture of the cis-and trans-isomer by NMR (see Figure ).

-This mixture could not be resolved into its components by any of six glc stationary phase used by us (each in columns with more than 20,000 theoretical plates) nor by careful chromatography on highly-activated AgNO3-Al203. A
