This paper dwells on the uvological characteristics of cultivar Vitis vinifera L. ‘Red Aladasturi’ grape raw materials growing in the viticulture and winemaking zone of Imereti (Georgia), as well as biologically active compounds and antioxidant activity of hydrophilic extracts and liquid concentrates of its solid matters (stone and skin). Research also covered hydrophilic extracts of grape skin and stone thickened by the vacuum of ‘Red Aladasturi’ grapes raw materials, as well as the concentrates produced from their composition. For research, there were used gravimetric, extractive, spectral and chromatographic methods. We processed samples of grapes raw materials according to the following pattern: identifying qualitative indicators of grapes raw materials; passing grapes raw materials through the DMCSI-type grape clustercomb divider; pressing-out the combless must in a basket press and separation of juice; vacuum sublimation drying of juiceless sweet pomace with an initial moisture content of 45–65% to a final moisture content of 9–10%; separation of the ‘Red Aladasturi’ cultivar’s skin and stone dried to the moisture content of 9–10%, using tea sorting machine designed by G. Lominadze; crushing separately the skin and stone in a micro-mill (TP2 Hammer Mill) until the fraction of 50–100 µm. we have blended the obtained grape-stone ethanol and fluid extracts containing 74–75% of solid maters at an equal ratio (1:1:1) and assessed biologically active compounds and antioxidant activity in this composition. It has been established that the bio-flavanoid liquid concentrate ‘Red Aladasturi’ is strong antioxidant  (55.31–57.45%), and one tablespoon or 8–9 ml of it contains 110–127 mg of flavanoids, which is 105–110% of a full day of rations per person per day.

The article presents Data on the content of biologically active compounds (BAC) and the total phenolic antioxidants activity (TPA) evaluated for leaves and inflorescences of Achillea millefolium, Anthemis tinctoria, Artemisia absinthium, A. dracunculus, Leucanthemum vulgare, Pyrethrum balsamita, P. macrophyllum, Tanacetum vulgare. The leaves and inflorescences of the plants contain flavonols, catechins, tannins, carotenoids, pectin substances. High content of phenolic compounds was found in Artemisia dracunculus and Achillea millefolium (352.34 – 398.99 mg/g of DW). The highest level of catechins was registered in inflorescences (8.01 mg/g) and leaves (4.58 mg/g) of Artemisia absinthium. The content of pectin substances in the studied plants was quite high, with the biggest share of protopectins (50.6 – 95.9 mg/g). The maximum quantity of pectins was found in the leaves and inflorescences of Leucanthemum vulgare (11.2-12.7 mg/g), protopectins – in the leaves of Tanacetum vulgare (95.9 mg/g). The highest content of carotenoids was found in the leaves of plants, except for Leucanthemum vulgare. The highest antioxidant activity was recorded for water-ethanol extracts from leaves of Achillea millefolium (up to 1.09 mg/g) and inflorescences of Artemisia dracunculus (0.94 mg/g) plants due to the increased content of phenolic compounds, in particular flavonols and tannins, compared to the other species.

The article presents Dara on the content of biologically active compounds (BAC) and the total phenolic antioxidants activity (TPA) evaluated for leaves and inflorescences of eight species from the Rosaceae family: Padus avium, Malus baccata, Alhemilla vulgaris, Potentilla inquinans, Filipendula vulgaris, F. palmata, Sanguisorba officinalis, S. alpina. It was determined that leaves and inflorescences contain flavonols, catechins, tannins, carotenoids, saponins, pectin substances. Usually, woody plants tend to accumulate less BAC and TPA than herbs. The highest level of flavonols and tannins was registered in inflorescences of F. vulgaris (12.25% and 45.02 %). The content of pectin substances was quite high, with the biggest share of protopectins (4.4-10.65%). The maximum quantity of catechins (4.76%) was found in the leaves of F. palmata, saponins – in the inflorescences of M. baccata (20.77%). The highest content of carotenoids was found in the leaves of plants, most notably in P. inquinans (1.00 mg/g). The highest antioxidant activity was recorded for water-ethanol extracts from inflorescences (up to 7.77 mg/g) and leaves (2.11 mg/g) of F. vulgaris and A. vulgaris plants due to increased content of phenolic compounds, in particular flavonols and tannins, compared to the other species.

In this study, we determined the effect of hormonization treatment on yield quantity and quality, content of biologically active compounds, and antioxidant activity in fruits and raisins of ‘Einset Seedless’ grapevine. Field studies were conducted in 2017 at Nobilis Vineyard (50°39′ N; 21°34′ E) in the Sandomierz Upland. Analytical studies were carried out in the Laboratory of the University of Life Sciences in Lublin. Hormonized fruits and raisins, which were dried at 40 °C in a food dryer for 7 days, were the experimental material. It was shown that the application of the hormonization treatment had a significant effect on yield size and quality. The hormonization treatment and the form of plant material analyzed had a significant effect on the content of biologically active compounds and the antioxidant activity in ‘Einset Seedless’ grapevine fruits and raisins. The concentration of applied gibberellic acid had a significant effect on the levels of acidity, content of anthocyanins, and antioxidant activity determined with the FRAP and DPPH methods. The application of the multivariate analysis technique showed that, in the fresh fruits and raisins, the level of biologically active compounds and antioxidant activity in the case of the 200 mg∙GA3∙L−1 concentration and in the control combination was similar but differed significantly in the case of the 300 mg∙GA3∙L−1 application.
