title: GC-MS analysis of essential oils from Salvia officinalis L.: comparison of extraction methods of the volatile components.
abstract: In this paper, comparison of the volatile components composition in the samples obtained by hydrodistillation and solid-phase microextraction of Salvia officinalis was described. Different sample preparation techniques showed considerable differences in volatiles composition, especially with respect to sesqui- and diterpenoids. The comparison of the sage essential oil obtained by hydrodistillation in the Deryng and Clevenger type apparatus, according to the pharmacopoeial methods (FP VI and VII), showed the presence of the same terpenoids in both essential oils, however, the relative percentage composition of the components were different. These differences are caused by the different extraction times used in both methods. Since each essential oil to be admitted to medicinal use should meet requirements regarding the composition of major chemical components, the minimum time for the hydrodistillation of the essential oils from sage should be 1 h.
