Abstract:

The species Thymus comosus grows spontaneously in the Romanian flora, at altitudes of 400-700 m, and it is harvested for obtaining the collective herbal drug Serpylli herba.
The content of essential oil of this species was assessed and the chemical composition of the essential oil was analysed by gas-chromatography coupled with mass spectrometry. A content of 0.09 - 0.1 % essential oil was established. The main compounds identified in T. comosus essential oil were: caryophyllene-oxide (54.82 %), camphene (10.73 %), β-bourbonene (5.90 %), eudesmol (3.65 %), α-pinene (3.67 %).
