Quality Numerical Indicators of Raw Materials of Sanguisorba Officinalis L. Growing on Overburden Dumps of Kuzbass Coal Surface Mines

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.
