The efficiency of using combinations of retention indices and partition coefficients ( K p ) with a hexane: acetonitrile system has been demonstrated by taking as an example the essential oil from Artemisia pallens Wall. Preliminary partition of the components between the two partly mixing liquids provides information by which components can be attributed to the appropriate homologous series. The use of group constants ( j ), which are functions of both partition coefficients and GC retention indices, in the practice of identifying the components of essential oils is reported for the first time.
