Essential oil composition and antibacterial activity of the different parts of Thymus maroccanus Ball: an endemic species in Morocco.

Three essential oils from three samples: stems, leaves and inflorescences of Thymus maroccanus Ball, obtained by hydrodistillation, were analysed by gas chromatography and gas chromatography coupled to mass spectrometry. The oils of stems, leaves and inflorescences afforded 68, 49 and 51 constituents, respectively. Quantitative and qualitative differences have been found between the analysed parts.

Quantitative analysis of some oligo-elements and heavy metals in some species of Thymus from Morocco.

In order to valorise natural substances, concentrations of 20 mineral elements were evaluated in five species of Moroccan thyme. These species which belong to the Lamiaceae family are Thymus leptobotrys, Thymus broussonetii, Thymus maroccanus, Thymus pallidus and Thymus satureioïdes growing in different regions of central and southern Morocco. Samples of plants were subjected to digestion and heavy metals were determined by inductively coupled plasma mass spectrometry.
