Abstract
Essential oils are used in perfumes, cooking and in pharmacy. A special study had
been done on essential oils issued from two plants of Lavendin and Rosemary, during
the annual biological cycle. The GC/MS technique was used and identification of
separated components was achieved by retention times in comparison with respective
standards and by mass spectra comparison. Quantitative determinations of camphor,
cineol, linalool, linalyl acetate in Lavendin, and camphor, -pinene, cineol in
Rosemary, were done by GC/FID. n-Dodecane was used as internal standard. The aim
of this study was to choose the optimum period of plant gathering, with respect to
the level of camphor and other major components. An increasing of the camphor is
observed in the leaves. Camphor, present in essential oils of Lavendin and Rosemary,
has new pharmaceutical applications, mainly as stimulant, cardiac and respiratory analeptic.
Key words: Camphor -- essential oils -- GC/MS -- GC/FID -- Lavendin -- Rosemary.
