Aim. The aim of the work was to evaluate the anti-radical activity of extracts of ginseng's underground and overground organs Panax ginseng C.A. Mey, depending on various factors – age of plants, collection time and cultivation conditions. Methods. Extracts obtained from various plant organs were evaluated in the model system with cation-radicals ABTS. At the same time, the amount of extractive substances and phenolic compounds was determined. Results. Samples of leaves and roots of ginseng of 1, 2, 3, 5, 9 years of vegetation from the collection of the Central Botanical Garden of the National Academy of Sciences of Belarus were analyzed. It is established that extracts of ginseng leaves of P. ginseng can be considered as sufficiently effective anti-radical agents. Anti-radical activity of extracts of roots and leaves of ginseng differed significantly depending on the weather conditions of the growing season. Conclusions. It is shown that extracts of ginseng leaves differ by the maximum antiradical activity. Extracts of ginseng roots showed a much lower anti-radical activity in comparison with leaf extracts, which may be due to both a smaller amount of extractives extracted from water-ethanol extraction and their composition. Keywords: ginseng, antiradical activity, phenolic compounds, extractives.

For the first time, a detailed study of the qualitative and quantitative composition of ginsenosides in the Panax ginseng roots was carried out with the help of high-performance liquid chromatography combined with mass spectrometry (HPLC-MS). The plants were introduced into the conditions of the Republic of Belarus at the experimental plot of the Central Botanical Garden of the National Academy of Sciences of Belarus. It was found that in the examined roots, all basic neutral glycosides of ginseng (ginsenosides Rb1, Rc, Rb2/Rb3, Rd, Rf, Rg1 and Re), as well as their malonylated derivatives (malonylginsenosides Rb1, Rc, Rb2/Rb3, Rd, Rg1 and Re) and some “minor” ginsenosides (20-gluco-ginsenoside Rf, notoginsenosides R1 and R2, isomers of malonyl-ginsenosides Rb1 and Rd) are present. The research also showed that different parts of the P. ginseng roots differ significantly in a total content of ginsenosides: for the main root, this parameter was 3.3 % of dry mass, and for the lateral roots – 7.8 % of dry mass.

The tree peony, which is considered a traditional ornamental plant in China, Japan, America and Europe, is also widely used as a medicinal plant. The collection of tree peonies in the State Scientific Institution “Central Botanical Garden of the National Academy of Sciences of Belarus” is represented by four taxa. The aim of our work was to assess the quantitative composition of the sum of phenolic compounds and hydroxylcinnamic acids in the leaves of the genus Paeonia, as well as to assess the antioxidant status of these samples depending on the phase of ontogenesis. As a result of the studies, a high content of phenolic compounds and hydroxycinnamic acids in the leaves of the studied taxa of the genus Paeonia was established, including the content exceeding the threshold of 65 mg/g in the leaves of Paeonia suffruticosa in all observed phases of ontogenesis. In the studied varieties, the proportion of hydroxycinnamic acids in the composition of phenolic compounds ranged from 25 to 50 %. Extracts of leaves of the Paeonia genus collected during the flowering period had the maximum antioxidant activity. Thus, the above data indicate that the aerial part of the Paeonia genus can be considered as a promising raw material for the creation of herbal remedies with antioxidant action.

Data on a genus of the Daffodils have been given in the article. The areas of species have been designated. Dates of selection work for the Daffodils have been determined. Countries and number of plant breeders of the Daffodils have been presented. The first cultivar of the Daffodil with pink crown has been specified, too.Group accessory for the 55 Daffodils from the collection of the Central Botanical Garden of NAS of Belarus has been defined. The age and authorship of the studied cultivars have been established. Assessment of their biological features in the conditions of the Central area of Belarus has been carried out. Periods and duration of some phenological phases have been established. Height of plants and sizes of flowers have been estimated. Periods of the Daffodils with a pink crown blossoming have been established. The abundance of blossoming depends on cultivar’s features and duration of their cultivation without grafting. The flowers of Daffodils with a pink crown have been measured from 6.5 to 11.5 cm. For the long-cupped Daffodils sizes and forms of crowns are various. The multiplication factor during the three years cultivation fluctuates from 5 to 16 units. Grades are rather steady in local conditions against diseases and pests.From studied cultivars the 13 best ones have been recommended for cultivation.

The content, component composition, and main directions of the use of monoterpenes of wild rose petals compounds are considered in the research. The study on six wild rose species was carried out in the collection of M.M. Gryshko National Botanical Garden of the National Academy of Sciences of Ukraine. Volatile organic compounds were isolated by steam distillation, and their determination was performed by means of gas chromatography. R. rugosa petals contained the highest number of monoterpenoids, while R. canina petals – the lowest. In our research twentyone different (acyclic, monocyclic, bicyclic) monoterpenoids were identified, including alcohols, aldehydes, ethers, and ketones. All groups of monoterpenoids are biologically active substances and have a significant effect on the aroma of the studied plants.

The article contains information on the presence and vital state of the natural renewal of 10 species of fir growing on the territory of the Central Botanical Garden of NAS of Belarus.Under the conditions of introduction, the investigated species of fir give a viable self-seeding, though not always abundant and uniform. The best indices of height and diameter of the root neck of different ages are the shoots of A. nordmanniana and A. sibirica. A. alba, A. nordmanniana and A. sibirica have the largest number of self-sowing adults of the older age group. In all investigated firs, the vital state of the shoots is estimated as healthy.

Recently, with the development of decorative gardening and landscape design, the extension of the assortment of floral and ornamental plants including perennial plants becomes relevant. chrysanthemum Korean – one of the most promising crops for flower decoration of the cities of Belarus, characterized by long flowering periods, unpretentiousness at cultivation, accessible ways of reproduction ways of plants, a wide variety of varieties. In the article present a modified method of comprehensive assessment of chrysanthemum Korean (Chrysanthemum coreanum), recommended for use in industrial landscaping. The method is based on 11 decorative and biological qualities: stability of flower coloration, duration and stability of flowering plants, number of inflorescences, height and shape of the plant, number of leaves on the stem, winter hardiness of plants, resistance to diseases and pests, ability of plants to vegetative reproduction, preservation of decorative qualities without plant transplantation which are important for industrial cultivation of plants. Each qualities is evaluated on a 3-point scale. The sum of points determines the perspective of the variety for use in gardening. Varieties of chrysanthemum that received 27 points or more are very promising plants, 19–26 – a promising plants, below 18 points – to the unpromising plants.The method was used on a collection of chrysanthemum Korean of the Central Botanical Garden of the National Academy of Sciences of Belarus. Based on this technique, perspective plant varieties were selected for the green construction of Belarus.
