Abstract

Medicinal plant materials quality assessment of the Sanguisorba officinalis L. growing on the Kedrovsky coal mine dumps in Kemerovo region is given. The analysis of obtained burnet raw material quality indicators (moisture, total ash, insoluble in hydrochloric acid, quantitative content of tannins, heavy metals, radionuclides) showed that this vegetable raw material match with the requirements of PhI.2.5.0078.18 “Sanguisorba officinalis L. rhizome and roots”. Tannins average content in the burnet rhizomes and roots was 15.708 ± 0.307%, which is within the normal range (up to 14%). It was found that the heavy metals (Pb, Cd, Hg) content does not exceed the MPC adopted for medicinal plant raw materials (G.Ph.A.5.5.000.0009.15). The obtained indicators for the artificial radionuclides (Cs-137, Sr-90) content showed that their quantity in the raw material is also within the normal range and their actual content is several times less than the normalized one. From the point of radiological safety view the studied raw materials are not dangerous since they accumulate 0.36% Sr-90 and 0.42% Cs-137 from the levels established by regulatory documentation. Therefore, the burnet medicinal plant raw material harvested at the Kedrovsky open-pit coal mine on the territory of waste dump does not represent a danger to human health.

Highlights

A Rosaceae family (Rosaceae) representative (Sanguisorba officinalis L.) is found among the herbaceous plant on the Kuzbass coal mines rock dumps
The objects of study were the greater burnet rhizomes and roots collected in the summer season in the period 2017-2018 on the “Yuzhny” rock waste of Kedrovsky coal mine in Kemerovo region
The Sanguisorba officinalis L. raw material harvested on the “Yuzhny” rock waste of Kedrovsky coal mine analysis showed that its rhizomes and roots, according to all studied parameters: moisture, total ash, ash insoluble in hydrochloric acid, the content of tannins, comply with the requirements of PhI 2.5.0078.18 "Sanguisorba officinalis L. rhizome and roots" and does not pose a danger to human life and health

Summary

Introduction

A Rosaceae family (Rosaceae) representative (Sanguisorba officinalis L.) is found among the herbaceous plant on the Kuzbass coal mines rock dumps. The burnet thicket is marked mainly on meadows, in inter-dump depressions, on the dumps tops in the rock heaps of Kedrovsky mine cut territory. The plant prefers mainly loams [1,2]. It does not form commercial thickets, the local population produces a medicinal plant raw material harvesting of Sanguisorba officinalis L. The burnet rhizomes and roots (Rhizoma cum radicibus Sanguisorba) are pharmacopoeial raw materials.
