The purpose of study is to identify possibilities of using fruits of eleutherococcuses Eleutherococcus senticosus Rupr. & Maxim. аnd Eleutherococcus sessiliflorus Rupr. & Maxim., which are undergoing introduction tests in arboretum of N.V. Tsytsin Main Botanical Garden of Russian Academy of Science, as easily renewable biosafety drug and food resource. By standard methods, comparative morphology-anatomical and morphometric study of fruits was carried out; content of air-dry, absolutely-dry substance and ascorbic acid was determined in them; statistical processing of the results was performed. The fleshy drupes that we studied vary in fruits shape, by number, shape and size of stones. Features and similarities of anatomical structure of exocarp, mesocarp and endocarp of fruits, typical for most members of the Araliaceae family, were revealed. Fresh fruits of E. senticosus are smaller and lighter than fruits of E. sessiliflorus, but surpass them in terms of volume of stones and amount of ascorbic acid; content of absolutely-dry matter in them is equally high. We propose to consider fruits of both types as a new promising raw material for the production of biologically active additives and functional foods, alternative to traditional raw materials from roots of eleutherococcuses, traumatic to the plants.

In connection with the state policy of import substitution and fortification of food products, in the Russian Federation, the search, study and introduction of new types of domestic non-traditional plant materials into the food industry are relevant. The purpose of the study is comparative analysis of the size and weight characteristics of cynarodies (fruits) of rosehips undergoing introduction tests in the arboretum of the N.V. Tsytsin Main Botanical Garden of Russian Academy of Sciences, to find out the possibilities and advantages of their industrial and domestic use. The objects of the study are mature infructescences of hips growing abundantly in the conditions of Moscow region: Rosa amblyotis C.A. Mey, Rosa maximowicziana Regel and Rosa oxyodon Boiss. The determination of the length, diameter, weight of cynarrodies, the content of absolutely dry substances in them, as well as the statistical processing of the research results were carried out according to standard methods. The reliability of interspecies differences of analyzed traits were established according to criteria of Student and Fisher. The superiority of the most variable fresh and air-dried cynarrodies of R. oxyodon in length, diameter and weight (2.02×1.18 cm and 1.08 g, respectively) was revealed, compared to the smallest and least changeable infructescences of R. maximowicziana (0,86×0.90 cm and 0.34g), as well as of R. amblyotis fruits which are intermediate in terms of these characteristics (1.06 x1.22 cm and 0.74 g). However, infructescences of R. amblyotis, containing an increased percentage of absolutely dry substance (94%), turned out to be no less promising than larger ones due to the significant water content of R. oxyodon cynarrodies (90%). For final determination of industrial significance of investigated rosehips infructescences, the size and weight study we have undertaken is not enough; further biochemical analysis is required.

The relevance of the search for alternative plant raw materials to enrich the diets of population throughout the world, including in the Russian Federation, is explained by global mass year-round insufficiency of biologically active nutrients in food. This work is aimed at identifying the most promising food plant species from the list, proposed on basis of long-term observations by staff of Tsytsin Main Moscow Botanical Garden of Russian Academy of Sciences (MBG RAS), by bachelors, studying in direction 06.03.01 (Biology) at Moscow State University of Food Production. The research materials (2016-2018) are fruits of hawthorns, rosehips, quince, eleutherococcuses, medlar, mahonia, spindle tree, yews, sumacs, oaks, red-fruited honeysuckles and needles of coniferous plants. Research results indicate the value of studied raw materials as a whole and its advantages in compared species within the genus of plants. Some recommendations for practical usage were made. The following things have been proposed: separation of fruit pulp and seeds before drying of fruits of Crataegus submollis and more preferable C. punctata; wide plantation cultivation of rosehips Rosa amblyotis and R. oxyodon; non-waste separate application of pericarp and seeds of Cydonia oblonga, Mespilus germanica and Mahonia aquifolium; medicinal use of fruits of Eleutherococcus sessiliflorus , and more preferable E. senticosus ; further study of cones of Taxus baccata and T. media; as a spice there is usage of fruits of Rhus typhina ; obtaining unique oils from fruit pulp of Lonicera glehnii, L . ferdinandii, L. maackii and arils of Euonymus europaeus; usage of acorns of Quercus robur, Q. rubra and needles of Picea abies, Pinus sylvestris in feed production. Thus, possibilities of intensifying plant resource usage in the food industry and agriculture were discovered, primarily due to fruits of native introduced species. It is necessary to continue search and further study of the most promising species - sources of alternative plant raw materials.
