It is proposed to modify the method of obtaining self-compacting masses by changing the nature of the compacting component ― from expensive and environmentally unsafe polystyrene to a burnable plantbased additive that can self-absorb shrinkage moisture from the molding material enclosed in a hydraulically closed volume. At the same time, part of the mixing water under pressure penetrates into the clay particles with pre-modified physicochemical properties of the surface, forming a semi-permeable shell. Ill. 3.

The application of chemicals in industry and agriculture has contributed to environmental pollution and exposure of living organisms to harmful factors. The development of new pharmaceutical agents enabled successful therapy of various diseases, but their administration may be connected with side effects. Oxidative stress has been found to be involved into etiology of numerous diseases as well as harmful action of drugs and chemicals. For some time, plant origin substances have been studied as potential protective agents alleviating toxicity of various substances and symptoms of diseases. The aim of the current review was to present the diversity of the research performed during the last five years on animal models. The outcomes showed a huge protective potential inherent in plant preparations, including alleviating prooxidative processes, strengthening antioxidant defence, ameliorating immune parameters, and reversing histopathological changes. In many cases, plant origin substances were proved to be comparable or even better than standard drugs. Such findings let us suggest that in the future the plant preparations could make adjuvants or a replacement for pharmaceutical agents. However, the detailed research regarding dose and way of administration as well as the per se effects needs to be performed. In many studies, the last issue was not studied, and in some cases, the deleterious effects have been observed.

The Past

The role of purified natural products in the prevention and treatment of countless diseases of bacterial, fungal, and viral origin cannot be overestimated. New antiviral drugs have been obtained from natural sources and transformed into preparations for prophylactic and therapeutic purposes. Flavonoids, polyphenols, saponins, proanthocyanins, polysaccharides, organic acids, proteins, polypeptides, and essential oils derived from plants, animals, or microorganisms can control and combat foodborne viral infections, including hepatitis A. The components of essential oils are characterized by numerous therapeutic and antioxidant properties and exhibit a broad spectrum of antimicrobial and antiviral activity. Due to these properties, they can be used to preserve meat, fruit, vegetables, and their products. Over the past two decades, much effort has been made to identify natural products, mostly of plant origin, to combat foodborne viruses. Natural plant extracts have several potential uses, not limited to increasing the safety of food products and improving their quality, but also as natural antiviral agents.

Active Substances

In modern food products, food additives of natural origin are increasingly used. The search for ef-fective antioxidants of plant origin is a widely studied topic at the present time. The study of this issue makes it possible to introduce the latest solutions in the fight against lipid oxidation in food products. The aim of this scientific work was to evaluate the radical-binding capacity of plant ex-tracts with different contents of active substances. As a result of a series of experiments using the DPPH method, the antioxidant properties of 14 samples were investigated. It was found that the greatest antioxidant activity among the tested extracts is possessed by extracts of green tea, apple, grape seed, sorghum. The rest of the samples are moderately active.
