The steam distillation method was used to obtain samples of essential oil of some species of genus Agastache L. introduced in Belarus. More than 20 components have been identified and determined in the essential oils of Agastache pallidiflora ssp.neomexicana L., Agastache aurantiaca L., Agastache mexicana L., Agastache foeniculum L. by gas liquid chromatography. The quantitative composition of the samples of essential oils depends on the type of plant material. The main its components are limonene, 1.8-cineol, mentone, isomentone, methyl chavicol, methyeugenol. The main component of essential oils Agastache pallidiflora ssp. neomexicana L. и Agastache aurantiaca L is mentone (40–65 %). Essential oil Agastache foeniculum L. is enriched with pulegone and isomentone. Methyl chavicol and methyleugenol dominate in Agastache mexicana essential oil. Distribution of the enantiomers of limonene, menthone and pulegone are shown. Regardless of the plant species, the samples are optically pure in the (+)-pulegone. The nature of the distribution of the enantiomers of limonene and menthone is an individual characteristic of the studied Agastache L. essential oils.
