“…Сравнительный анализ микроскопических признаков побегов боярышника мягковатого и сырья других видов, описанных в литературе, позволяет сделать вывод о некоторых чертах сходства с другими близкородственными представителями [4,8,9]. Характер верхнего и нижнего эпидермиса листа, наличие сидячих железок по краям листа, сосочковидные выросты на эпителии лепестков типичны для многих представителей рода (Crataegus sp.).…”

“…Железки на ножке сосредоточены на чашелистиках, прицветниках и прилистниках. Наличие большого количества железок на чашелистиках боярышника мягковатого является яркой чертой, позволяющей отличить его от аналогичных видов сырья боярышника [4,8,9]. Результаты исследования морфолого-анатомических признаков цветущих побегов боярышника мягковатого будут включены в проект фармакопейной статьи на данное сырье.…”

Aim to conduct a morphological and anatomical study of dried shoots of soft hawthorn collected during the flowering period. Material and methods. The shoots of soft hawthorn were collected during the flowering period in the Botanical Garden of Samara University. The micro-preparations were immersed in an alcohol-water-glycerin mixture (1:1:1). To determine the lignified elements of stems and pedicels, a solution of 2% aniline sulfate in 50% ethanol was used. The samples of raw material were examined in daylight using a magnifying glass and a "Motic DM-39C-N9GO-A" binocular. The microscopic examination was performed in transmitted and reflected light using a digital microscope Carl Zeiss Primo Star 415500-0057-000 (Imaging Software for Microscopy ZEN soge V2.7). Results. The study of anatomical and morphological properties of hawthorn shoots revealed their most characteristic feature - the abundant pubescence with simple hairs. In addition, the edge of the leaf blades, bracts and sepals had multicellular glands with brown contents. Conclusion. The anatomy of the petiole of the hawthorn leaf was described for the first time. The study allows us to identify characteristic changes in the conducting system of the leaf. The morphological and anatomical analysis allows us to identify the common features of the semi-soft hawthorn and closely related species.

Identification of scientific regularities of accumulation of physiologically active compounds is relevant to the issues of plant biology, as it can create conditions for the rapid development of biotechnological approaches and the solution of a number of environmental and economic problems associated with the use of plant raw materials. The aim of this work was to identify the features of the accumulation of flavonoids and the development of methods of differential spectrophotometry allows to assess the quality of biotechnological raw materials Iris sibirica L. (Siberian iris) on the content of flavonoids. The most important regulators of the synthesis of secondary compounds in plant tissue cultures include such components of nutrient media as hormones. As a result of our experiments it was noted for I. sibirica characteristic relationship between the accumulation of biomass and the content of quercetin and rutin. On the medium with 5.0 µm BAP, supplemented by auxins with an increase in the total height of the shoots, the quercetin content and rutin in the phytomass decreased dramaticly. To maintain a balance between biomass accumulation and flavonoid content for I. sibirica, we recommend using media with 2.5 µm BAP supplemented with auxins. The developed method allows to determine the content of the total of flavonoids in Iris sibirica raw materials in the presence of other compounds, is simple in execution and does not require expensive equipment. A validation evaluation of the technique indicates its suitability for quality control of biotechnological raw materials Iris sibirica.

The work involved the phytochemical study of hawthorn fruits (Crataegus oxyacantha L.). Hawthorn fruits were collected in areas with low anthropogenic impact (landscape and recreational areas) and in areas with the transport infrastructure in Kaliningrad city. The content of total phenolic compounds and subgroups: catechins, leucoanthocyanins, flavonoids, tannins); monosaccharides (glucose and fructose), pectins, organic acids, ascorbic acid, macro- and microelements, as well as antioxidant activity in hawthorn fruits were studied. The influence of the anthropogenic factor on the variability of their chemical composition was shown. It has been established that hawthorn fruits from areas with minimal impact of anthropogenic factors can accumulate phenolic compounds (up to 15.9 mg/g), leucoanthocyanins (up to 1.5 mg/g), tannins (up to 6.5 mg/g ), catechins (up to 4.1 mg/g), flavonoids (up to 6.0 mg/g), fructose (up to 14.1%), pectin (up to 11.6%), organic acids (1.45%), ascorbic acid (up to 49.3 mg/100 g), calcium (up to 12.12 mg/g), zinc (up to 39.12 mg/kg) more intensively and demonstrated higher antioxidant activity (up to 9.7 mg/g). The cluster analysis carried out on the content of phytochemicals proved the dependence of the accumulation of nutrients in hawthorn fruits on the growing conditions of plants. The obtained results allow us to consider the fruits of hawthorn C. oxyacantha as a valuable raw material for use as food additives for various purposes.
