A large number of biologically active substances, organic acids, tannins, and pectin substances were detected during the study of fruits, leaves, and pulp of the fruits of mountain Ash. The content of these substances in leaves and pulp will significantly expand the arsenal of medicinal plant raw materials used. Given the wide distribution of mountain Ash in the territory of the Russian Federation, harvesting leaves from the same plants after harvesting the fruit and using pulp will make it possible to obtain new phytopreparations.

Представлены результаты изучения влияния растительных адаптогенов на основе облепихи крушиновидной, боярышника обыкновенного, рябины обыкновенной и каштана конского на уровень железа при его дефиците, оксидантно-антиоксидантный статус и молочную продуктивность коров, содержащихся в условиях промышленного комплекса. Были сформированы 5 групп животных по 10 голов. Животные I (контрольной) группы получали основной рацион (ОР) II ОР измельченные семена каштана конского 50 г на 1 голову в сутки III ОР измельченные семена каштана конского 30 г высушенные плоды рябины обыкновенной 20 г на 1 голову в сутки IV ОР цельнозамороженные плоды облепихи крушиновидной 200 г на 1 голову в сутки V ОР цельнозамороженные плоды облепихи крушиновидной 130 г высушенные плоды боярышника обыкновенного 40 г на 1 голову в сутки. В опытных группах II, III, IV и V обнаружено увеличение содержания железа в сыворотке крови к 20-му дню эксперимента на 87, 78, 41 и 58, соответственно. Наблюдалось постепенное снижение уровня свободно-радикального окисления к 30-му дню опыта у коров этих групп. Уровень малонового диальдегида (МДА) снизился на 37,5, 13,4, 20 и 20, соответственно. Увеличение среднесуточного удоя отмечено у коров, получавших комплекс растительных средств из семян каштана плодов рябины (на 7,4) и плодов облепихи плодов боярышника (на 7,5).The resalts of impact studies of plant-based adaptogens (sea-buckthorn, hawthorn, mountain ash and chestnut) on serum iron level in cows, oxidative-antioxidant status and milk production of cattle contained in the industrial complex were shown. 5 groups were formed with 10 animals each: 1st control group (I) - animals received the main diet (MD) 2nd group (II) - MD chestnut seeds (50 g per 1 animal) 3rd group (III) - MD chestnut seeds/ mountain ash (30 g/20 g per 1 animal) 4th group (IV) - MD sea-buckthorn fruits (200 g per 1 animal) 5th group (V) - MD sea-buckthorn fruits/ hawthorn fruits (130 g /40 g per 1 animal). In experimental groups II, III, IV и V, an increase in the content of iron in blood serum by the 20th day of the experiment by 87, 78, 41, 58, respectively, was shown. There was also a gradual decrease in the free radical oxidation level by the 30th day of the experiment in cows of experimental groups II, III, IV и V, the malondialdehyde level (MDA) decreased by 37.5, 13.4, 20, 20 respectively compared to the initial values. The highest average daily milk production was observed in cows receiving a complex of herbal remedies from chestnut seeds mountain ash fruits (an increase by 7.4) and sea-buckthorn fruits hawthorn fruits (an increase by 7.5).

Four RNAs from a new plant-pathogenic virus, which we have tentatively named European mountain ash ringspot-associated virus (EMARAV), were identified and sequenced completely. All four viral RNAs could be detected in previous double-stranded RNA preparations. RNA 1 (7040 nt) encodes a protein with similarity to the RNA-dependent RNA polymerase of different members of the Bunyaviridae, a family containing five genera with viruses infecting invertebrates, vertebrates and plants. RNA 2 (2335 nt) encodes a 75 kDa protein containing a conserved motif of the glycoprotein precursor of the genus Phlebovirus. Immunological detection indicated the presence of proteins with the expected size of the precursor and one of its processing products. The amino acid sequence of protein p3 (35 kDa) encoded by RNA 3 shows similarities to a putative nucleocapsid protein of two still unclassified plant viruses. The fourth viral RNA encodes a 27 kDa protein that has no significant homology to any known protein. As is typical for members of the family Bunyaviridae, the 5′ and 3′ ends of all viral RNAs are complementary, which allows the RNA to form a panhandle structure. Comparison of these sequences demonstrates a conserved terminal part of 13 nt, similar to that of the bunyaviral genus Orthobunyavirus. Despite the high agreement of the EMARAV genome with several characteristics of the family Bunyaviridae, there are a few features that make it difficult to allocate the virus to this group. It is therefore more likely that this plant pathogen belongs to a novel virus genus.

In the late publication of the Department of Agriculture on “Foresttree Imsects” three species are mentioned as affecting the trunk of Pyrus americana, viz: The round and flat-headed apple-tree borers and an unknown longicorn larva. I have recently found two additional species fully as injurious as those mentioned. These are Podosesia syringœ and Zeuzophora semifuneralis.
