One of the valuable aromatics and medicinal plants of the Thymus L. genus is Thymus
striatus Vahl. The above-ground part of the plant in the flowering stage and drugs obtained from
it exhibited antibacterial properties. The essential oil contains thymol and carvacrol that
demonstrated antiseptic and fungicidal properties.
This study was aimed to investigate the content of essential oil and its components from
Thymus striatus cv. Yubileinyi that introduced from Nikitsky Botanical Garden to the Kherson
region of Ukraine. An investigation was carried out during 2019–2020 on the experimental
collection of aromatic and medicinal plants of experimental facility “Novokakhovske” of Rice
Institute (Kherson Region). Mass fraction of essential oil determined by the method of
hydrodistillation with Clevenger apparatus from fresh plant raw material. Essential oil
composition investigated on Agilent Technology chromatograph 6890N with mass-
spectrometric detector 5973 N.
Th. striatus cv. Yubileinyi evergreen plants that in Steppe zone conditions of South of
Ukraine formed large, compact shrub with a height of 30–35 cm and diameter of 70–75 cm.
Flower shoots rounded-rhomboid, pubescent. Leaves oblong-rhomboid with a length of 5–6
mm, the weight of 3–3.5 mm, tapering to base, well-defined petioles, cobweb-pubescent. Leaf
edges wrapped on the underside. Corolla from lavender to white color. These plants complete
the full development cycle in conditions of the Kherson region, bloom and fruit abundantly. Full
blooming was observed at the end of May – the start of June. During the investigation period
plants didn’t damage by pests and were not affected by diseases. The harvest of flower raw of
Th. striatus cv. Yubileinyi (plants of 3 year of growing) varied from 170 to 670 g, from one
rd
shrub. Mass fraction of essential oil was from 0.25 to 0.45 % FW or from 0.95 to 1.69 % DW. In
essential oil, obtained from plants growing in an experimental facility “Novokakhovske”,
identified 21 components. Basic components are thymol (57.27 %), para-cymene (10.18 %), γ-
terpinene 11.87 %, trans-sabinenhydrat 11.87 %.
Thus, Th. striatus cv. Yubileinyi can be perspective aromatic and essential oil plants in the
Kherson region. Obtained results can be used for further investigation on different biological
peculiarities of these plants for wide use.

Keywords: Thymus striatus, cultivar, essential oil.
