Accumulation of Reducing Sugars by Small-leaved Linden Flowers (Tilia cordata Miller, 1768) in the Voronezh Region of Russia

Introduction . Small-leaved linden flowers are mainly used for aquatic extracts, and their pharmacological benefit is based on water-soluble polysaccharides. Aim. The aim of this study was to investigate the rate accumulating all reducing sugars in small-leaved flowers, collected agro- urbo-cenoses Voronezh region. Materials methods. 51 sites were selected collecting from linden, which a widespread deciduous tree species Russia. In order determine total level samples, we measured glucose levels using method described Pharmacopeia article "Linden Flower". Correlation coefficients analyzed examine detail effect major pollutants (heavy metals arsenic) accumulation flowers. Results discussion. All samples medicinal plant raw materials benign terms sugar levels. Samples control (protected) areas contained 13.31 16.89 %, 6–8 times more than lower numerical value established by Pharmacopoeia article. agrocenoses region, concentration varied 6.12 16.68 3–8 given urbocenoses found compared protected (2.35–13.49 %). showed noticeable negative impact cadmium, chromium, cobalt, copper, zinc, as well moderate lead mercury Conclusion. lowest concentrations detected harvested along streets large cities highways, roads railways. This suggests that anthropogenic factors might negatively these areas. At same time, it possible saccharide complexes have reacted with heavy instead complexing agent when quantitatively determined. would underrepresenting materials.
