Abstract
The Calamintha species, fam. Lamiaceae, originally from West and South Europe, were cultivated at SCDL Bacău. The essential oils were extracted by hydrodistillation; the separation and identifying of theirs components were made using a gas-chromatograph equipped with masspectrometrical detector. The obtained data emphasized a great variation of the composition of the essential oils. So, the essential oil from C. officinalis contained mainly pulegone and p-menthone; the one extracted from C.grandiflora contained germacrene D and β-cariophyllene; the essential oil from C. mentifolia contained rose furane; C. sylvatica provided an essential oil containing pulegone and isomenthone and the main components of the oil obtained from C. nepeta were estragol and menthone.
