Clary Sage Oil

The oils of the inflorescences of a Sicilian spontaneous biotype of clary sage that was grown in the vicinity of Sparacia (Sicily, Italy) were analyzed using GC-FID and GC/MS by Carrubba et al. (2002). As expected, the inflorescence oils that were obtained by hydrodistillation were found to be rich in linalool and linalyl acetate as shown in T-1. The authors also showed that the leaf oils produced from flowering plants were determined to possess the following range in composition:

delta-elemene (0.39–0.40%)

alpha-cubebene (< 0.01%)

alpha-copaene (5.3–5.8%)
