GC-MS analysis of the volatile profile and the essential oil compositions of Tunisian Borago Officinalis L.: Regional locality and organ dependency

摘要

Seeking to explore new local natural resources, volatile profile as well as essential oil compositions of Tunisian Borago officinalis L. were analyzed. The current study aims at investigating the effects of the geographic origin and the plant part (flowers, leaves, and rosettes leaves) on the volatile profile of Borago officinalis L. The aerial parts were collected from three bioclimate zones in Tunisia namely Tunis, Bizerte, and Zaghouan. The essential oils were extracted by hydro distillation. The chemical composition of the latter was determined by gas chromatography coupled to mass spectrometry. Furthermore, an experimental procedure combining solid phase microextraction and gas chromatography coupled to mass spectrometry was implemented to study the volatile profile of Borago officinalis L. It was set up to assess the influence of different plant organs obtained from various sites on the aromatic profile.
