• The purpose of this study was to determine chemical composition of the oil of T. serpyllum subsp. serpyllum plants collected in various localities in Lithuania and to define the chemotypes within this subspecies growing wild in Lithuania.
• Material and methods • In total 26 T. serpyllum subsp. serpyllum individual plants (samples) were collected at the flowering stage in July from 14 different sites in Lithuania. • The oils were isolated from the selected individual plants by hydrodistillation in a Clevenger-type apparatus (European Pharmacopoeia) during two hours. GC and GC/MS carried out the analyses of the essential oils.

Range of the amount (%) of the main components essential oil in different Thymus serpyllum subsp. serpyllum samples
Two dimensional dendrogram obtained in the cluster analysis of the essential oils of samples of Thymus serpyllum subsp. serpyllum: (E)- -ocimene, -cadinol, cis-p-menth-2 -en-1 -ol, 1, 8 -cineole, germacrene B
• This study proved that T. serpyllum subsp. serpyllum plants from the Northern climatic area don’t accumulate volatile phenolic compounds thymol and carvacrol in more remarkable amounts.
