Tripleurospermum inodorum (L.) Sch. Bip. is not used in Russian official medicine, however, this plant is extensively used in folk medicine. Previously, we proved the effect of scentless chamomile extracts on the growth suppression of such microorganisms as Staphylococcus aureus, Escherichia coli, and Candida albicans. It is topical to study the composition of polysaccharides and free sugars, which can have an antimicrobial effect, according to the literature data. The analysis has indicated that scentless chamomile flowers are richer in polysaccharides (2.58±0.04) than the herbs (1.68±0.05); the flowers also contain more sucrose and glucose. In terms of fructose content, herbs and flowers of scentless chamomile practically do not differ.

At the same time highly active substances belonging to new natural and synthetic drugs classes has been coming in medicinal practice. NMR spectroscopy approach has wide opportunities in increasing number of drugs analysis which must meet constantly increasing demands.

Nanotechnology is the most perspective direction in the modern science and technic. The great interest in entire world has been observing to nanoparticles properties and their fields of use investigation. Cerium dioxide is a perspective oxide material which has wide use in different branches of industry due to its unique physical and chemical properties. Burst of interest to cerium oxide nanoparticles development and use in biology and medicine takes has been taking place recently. Scientists in many countries have been carrying out cerium oxide nanoparticles efficiency of use against various diseases.
