Teucrium divaricatum Sieb. ssp. villosum (Celak.) Rech. fil. is a medicinal plant used in Lebanon. The hydrodistillation of the aerial parts of T. divaricatum yielded 0.27% (wt/wt) of essential oil; gas chromatography and gas chromatography/mass spectrometry analysis enabled the identification of 60 compounds representing 94.5% of the total oil. On the whole, the oil was constituted mainly by sesquiterpenes (64.6%), particularly sesquiterpene hydrocarbons (50.0%). The most abundant compounds were (E)-caryophyllene (30.1%) and caryophyllene oxide (6.1%). The in vitro activity of the essential oil against some microorganisms in comparison with gentamicin by the broth dilution method was determined.

Abstract

Teucrium divaricatum Sieb. ssp. villosum (Celak.) Rech. fil. is a medicinal plant used in Lebanon. The hydrodistillation of the aerial parts of T. divaricatum yielded 0.27% (wt/wt) of essential oil; gas chromatography and gas chromatography/mass spectrometry analysis enabled the identification of 60 compounds representing 94.5% of the total oil. On the whole, the oil was constituted mainly by sesquiterpenes (64.6%), particularly sesquiterpene hydrocarbons (50.0%). The most abundant compounds were (E)-caryophyllene (30.1%) and caryophyllene oxide (6.1%). The in vitro activity of the essential oil against some microorganisms in comparison with gentamicin by the broth dilution method was determined. The oil exhibited a good activity as an inhibitor of growth of Gram-positive bacteria.
