In agreement with the above data, cis-, trans-thujone andcamphor have been identified as characteristic metabolitesin the essential oils from all the samples of sage we haveinvestigated (Table 2) and their total amount in micropropagated plants (MPA and MPF) fully satisfy the officialrequirements.The comparison of the compositional profiles of theessential oils of the analyzed samples of sage gives,however, the opportunity of some considerations on themetabolism and physiology of the plant.
