Elemental analysis of
thyme herb
Abstract
Abstract. In this work, for the first time, an elemental
analysis of thyme grass (creeping thyme, lat. Thymus serpyllum L.),
growing on the territory of the Chuvash Republic (Cheboksary), was carried out
using the X-ray fluorescence method. In the studied samples, among the 22
chemical elements detected, potassium, calcium, phosphorus, silicon and iron
had higher content. Macroelements by content in mg/kg can be arranged in the
following descending order: K (12410) > Ca (8960) > P (6000) >S (1480)
> Cl (1280). The content of
microelements in thyme herb samples in descending order looks like this: Si (7590) > Fe (350) > Mn (80) > Zn
(30) > Sr (20) > Cu, Br (10). Titanium (40 mg/kg), rubidium and chromium (10 mg/kg) were found in the
samples. There are no toxic elements (cadmium, lead, mercury and arsenic), as
well as silver, zirconium and vanadium in the samples. The elemental
composition of Chuvash thyme was compared with samples from the Goris region of
Armenia and medicinal and herbal raw materials from manufacturers Phytopharm
LLC (Krasnodar Territory, Anapa) and Zdorovye LLC (Moscow region). The absence
of heavy toxic metals and arsenic, the rich macro- and microelement composition
of Chuvash thyme herb make it possible to recommend it as a medicinal and
herbal raw material for the production of various preparations for traditional
and traditional medicine, cosmetology, perfumery, cooking, etc.
