During the period 1995Β±1997 we have monitored the essential leaf oils of 16 taxa to see if their oil compositions were essentially stable. The results indicate that during the period of observation the compositions of all the essential oils were quite stable except for two species, which exhibited a
The essential oils from Salvia aurea L., Salvia ianthina Otto et A. Dietr., Salvia iodantha Fernald and Salvia cinnabarina M. Martens et Galeotti were analysed by means of GC/MS. A total of 89 components were identified and the variation of composition during the year of the first three species was
