The chemical composition of the
essential oil of the Sardinian Rosmarinus officinalis L. obtained by
hydro distillation and steam\hydro distillation was studied using GC-FID
and MS. Samples were collected at different latitude and longitude of
Sardinia (Italy). The yields ranged between 1.75 and 0.48% (v/w,
volume/dry-weight). A total of 30 components were identified. The major
compounds in the essential oil were alpha-pinene, borneol, (-) camphene,
camphor, verbenone, and bornyl-acetate. Multivariate analysis carried
out on chemical molecular markers, with the appraisal of chemical,
pedological, and random amplified polymorphic DNA data, allows four
different clusters to be distinguished. The antimicrobial and antifungal
tests showed a weak activity of Sardinian rosemary. On the other hand,
an inductive effect on fungal growth, especially toward Fusarium
graminearum was observed.
