Silver birch, Betula pendula Roth, is one of the most common trees in Europe. Due to its content of many biologically active substances, it has long been used in medicine and cosmetics, unlike the rare black birch, Betula obscura Kotula. The aim of the study was therefore to compare the antioxidant properties of extracts from the inner and outer bark layers of both birch trees towards the L929 line treated with acetaldehyde. Based on the lactate dehydrogenase test and the MTT test, 10 and 25% concentrations of extracts were selected for the antioxidant evaluation. All extracts at tested concentrations reduced the production of hydrogen peroxide, superoxide anion radical, and 25% extract decreased malonic aldehyde formation in acetaldehyde-treated cells. The chemical composition of bark extracts was accessed by IR and HPLC-PDA methods and surprisingly, revealed a high content of betulin and lupeol in the inner bark extract of B. obscura. Furthermore, IR analysis revealed differences in the chemical composition of the outer bark between black and silver birch extracts, indicating that black birch may be a valuable source of numerous biologically active substances. Further experiments are required to evaluate their potential against neuroinflammation, cancer, viral infections, as well as their usefulness in cosmetology.

Xylotrophic Basidiomycetes

The search for new natural sources of biologically active substances is a major issue in pharmaceutical industry. Xylotrophic basidiomycetes are common in forests worldwide, but as a prospective raw source of biologically active compounds they have not been studied as extensively as plants and other groups of fungi. The study is aimed to determine the chemical composition and antioxidant activity of extracts from 10 species of tinder fungi growing on birch and common in the forests in Russia. The chaga muchroom (Inonotus obliquus), traditionally used in medicine, was chosen as a standard species. Extracts from fruiting bodies were obtained with water or 95 % ethanol. They contained 4 to 8 types of free amino acids including 2 to 6 essential ones. Perennial basidiocarps were shown to be richer in phenolic compounds and poorer in amino acids than annual ones. Alkaloids and saponins were found in perennial basidiocarps of two species, saponins were also found in annual basidiocarps of one species. Water and alcohol extracts differed in composition and concentration of extractives, and showed different antioxidant (inhibition of lipid peroxidation) and antiradical (ABTS‑test, inhibition of NO production) activity. This way it was shown that the nature of the solvent extraction agent is important for the manifestation of biological activity. In most tests, water extracts from chaga showed better antioxidant properties; extracts from Piptoporus betulinus and Fomitopsis pinicola were also effective as antioxidants, which may be promising avenues for future research

The most important phytonutrients of sea buckthorn ( Hippophae rhamnoides L.) berry are carotenoids, flavonoids, anthocyanins, sugars, organic and amino acids, water and fat-soluble vitamins, tannins and pectin substances, phospholipids, macro- and microelements. In the Chelyabinsk region it is almost impossible to find well-groomed industrial plantings of sea buckthorn, since its main areas (600 hectares) are concentrated in amateur and home gardens. To form a healthy diet, it is important not only to ensure the safety of horticultural products, but also to raise the priority of signs that determine consumer demand, namely the quality and chemical composition of fruits, their saturation with the necessary micronutrients. While studying food and biologically active substances of sea buckthorn berries of the "Velikan" variety growing in different garden agrocenoses of the Chelyabinsk region it has been determined that sea buckthorn berries cultivated in the garden "Lokomotiv-1" (Chelyabinsk) contain more flavonoids (by 21.4 %), proteins (by 17.4 %), mineral elements - Al (in 5.3 times), V (3.4 times), Cu (3 times), Ti (2.4 times), Ca and Fe (1.9 times), Mn (1.5 times), in berries obtained in the garden "Dizelist-1" (Chelyabinsk region, Troitsk) contains more sugars (by 15.1 %), as well as Mo and Sr (2-2.3 times), Se (1.4 times), Cr (by 76.2 %), etc. In terms of Se content, the studied fruits exceed the clarke values by 4-6 times; in terms of Pb content, they turned out to be as close as possible to the upper limit of MPC according to the requirements of the Technical Regulations of the Customs Union. The study of the mineral composition of sea buckthorn is especially important in the context of the ecological disadvantage of the Chelyabinsk region due to the pollution of the environment with heavy metals.

The worldwide cocoa bean shell (CBS) generation is estimated at around 900,000 tons. In their composition, this coproduct showed several bioactive compounds like methylxanthines or polyphenolic compounds. Thus, the aim of this work was to investigate the effects of different particle sizes on the chemical composition, physico-chemical, bioactive compounds content, and antioxidant properties of flours obtained from cocoa (Theobroma cacao L.) bean shells. The flours obtained from CBS with different particle sizes had high content of dietary fiber (61.18–65.58 g/100 g). The polyphenolic profile identified seven compounds being epicatechin and catechin (values ranged 4.56–6.33 and 2.11–4.56 mg/g, respectively) as the most abundant compounds. Additionally, the methylxanthines theobromine and caffeine were quantified with values ranging from 7.12 to 12.77 and 4.02 to 6.13 mg/g, respectively. For the fatty acid profile, the principal compounds identified were oleic, stearic and palmitic acids. CBS had antioxidant capacity with all methods assayed. For DPPH, ABTS and FRAP assays values ranged between 2.35–5.53, 3.39–11.55, and 3.84–7.62 mg Trolox equivalents/g sample, respectively. This study suggests that cocoa bean shells may constitute a valuable coproduct for the food industry due to its high content in valuable bioactive compounds.

The results of investigation of oenotannins content in the seeds of different grape varieties are presented in the paper. It was demonstrated that the oenotannins content depends on the grape variety as well as on the geographycal zone of grape cultivation. A new procedure for water sollubilization of oenotannins by depolimerization has been elaborated. The mechanism of the oenotannins depolimerization has been reveiled by mass-spectrometric studies. It has been established, that the depolimerization process brings about formation of carboxilic acids and organic peroxides. The presence of the carboxilic and peroxidic groups was detremined on the basis of IR spectral analysis. It was demonstrated that the antioxidant properties of modified tannins are higher then those of initial unmodified ones.
