Comparative phytochemical study of herbs, rhizomes and roots of Sanguisorba officinalis L. in the Republic of Bashkortostan

The objects of research were grass, rhizomes and roots of S. officinalis. The analysis of raw materials was carried out on the basis of the Bashkir State Medical University. To assess the possible stocks of raw materials used the method of accounting sites and model copies. The qualitative and quantitative determination of biologically active substances was carried out in accordance with generally accepted and modified methods. Amino acid and elemental composition was determined by X-ray fluorescence method on the spectrometer "PacificScientific-6520". As a result of the resource study, it has been established that the possible stocks of raw material of the S. officinalis are quite high (grass is from 0.032 tons to 0.843 tons, rhizomes and roots are from 0.008 tons to 0.172 tons). In a comparative biochemical analysis, it was found that the herb of the S. officinalis is distinguished by a higher content of amino acids (8.01-8.27%), potassium (0.54-1.30%), sodium (0.19-0.28%) phosphorus (0.13-0.19%), zinc (24.18-53.12 mg/kg), iodine (0.12-0.21 mg/kg), organic acids (1.46-2.20%), ascorbic acid (0.315-0.521%), carotenoids (31.17-34.15 mg%), coumarins (0.285-0.324%). Rhizomes and roots are characterized by accumulation of more calcium (1.00-1.39%), iron (209.33-617.87 mg/kg), copper (9.82-13.54 mg/kg), manganese (356.13-385.57 mg/kg), polysaccharides (3.52-5.18%), saponins (2.93-3.69%), hydroxycinnamic acids (1.69-1.88%). Thus, it is possible to recommend the grass of the S. officinalis for waste-free harvesting of raw materials on a par with rhizomes and roots, which will solve the problems of integrated and waste-free processing of this plant as part of resource-saving technologies.
