RESUMO

The composition of six samples of essential oil (EO) extracted from leaves, flowers and seeds of several plants of Hyptis fruticosa Salzm. ex Benth., Lamiaceae, was investigated by GC/MS and GC/FID. 1,8-Cineole, spathulenol, α-pinene, β-pinene were the major constituents. Ten constituents that have not been previously described in the composition of the oil of H. fruticosa were identified. Hydrocarbons sesquiterpenes represented the main group, followed by hydrocarbons monoterpenes. The results were submitted to Cluster Analysis which allowed three groups of EO to be distinguished with respect to the content of α-pinene/β-pinene, 1,8-cineole and spathulenol. Growth stages of the plants and geographical parameters seem to be important factors determining the variability of the oil. Sesquiterpenes were mainly produced in the seeds.
