The aerial and underground areas of 34 Astragalus types contain triterpene saponins, flavonoids, polysacharides, tannins, no-cost organic acids, greater essential fatty acids, nutrients, trace elements, as well as other constituents. Among the Astragalus species, A. membranaceus (Fisch.) Bunge is the greatest studied with regards to of component composition and biological task. Anti-inflammatory, immunomodulatory, antioxidant, anticancer, cardioprotective, and hepathoprotective tasks were experimentally recognized as a whole bioactive substances, fractions, and individual substances obtained from various parts of A. membranaceus and A. membranaceus var. mongholicus in vitro as well as in vivo. The composition and biological ramifications of other Astragalus species are still defectively understood. The review summarizes the present improvements in studying new substances removed from Astragalus species and their biological activities.The total mineral content had been examined in medicinal flowers from roadside and railside biotopes of the Voronezh area. Pharmacopoeial plant natural materials of 10 types had been assessed roots of Taraxacum officinale F.H. Wigg and Arctium lappa L.; natural herb of Polygonum aviculare L., Artemisia absinthium L., Leonurus quinquelobatus Gilib., and Achillea millefolium L.; leaves of Urtica dioica L. and Plantago major L.; and flowers of Tanacetum vulgare L. and Tilia cordata Mill. Plant garbage were collected near roadways and railways of varied types in the periods specified in regulating papers. The total ash content in plant product was utilized to determine the minimum allowable distances from various roads and railways for obtaining plant material. The minimal allowable length from heavy-traffic motorways was suggested become 210 m within the forest zone, 240 m when you look at the forest-steppe area, and 380 m in the steppe area. A distance with a minimum of 80 m was suitable for additional low-speed roads and railways.The wild soybean Glycine soja Sieb. et Zucc. is an ancestor associated with cultivated soybean Glycine max (L.) Merr. and a source of many important genes lacking when you look at the G. max genome, including genetics that determine anxiety opposition to adverse environmental factors. Biochemical parameters (protein, oil, ascorbic acid, carotene, greater efas, and certain tasks and multiple kinds of enzymes regarding the oxidoreductase and hydrolase courses) were studied in five G. soja accessions from the selleckchem number of the All-Russian Institute of Soybean (КА-1413, КА-342, КBl-29, КBl-24, and Kеl-72). The accessions offer special all-natural gene banking institutions. Wild seeds were collected in three districts (Arkharinskii, Blagoveshchensk, and Belogorskii) of Amur Oblast. According to superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), polyphenol oxidase (PPO), ribonuclease (RNase), acid phosphatase, esterase, and amylase (AML) activities and biochemical variables of seeds, the G. soja accession KA-1413 was found to own higher items of protein, oleic acid, and linolenic acid; a lowered polyphenol oxidase certain activity; and higher activities of SODs, esterases, and RNases. The accession KA-1413 was therefore recommended to make use of as a source of principal genetics in reproduction to increase brain histopathology the adaptive potential of the latest soybean varieties. A higher heterogeneity of several kinds had been observed for SOD, AML, RNase, and esterase, which could provide markers of adaptation to environmental conditions.The Tip-Tugai Cave (52°59’28.6″ N, 57°00’22.3″ E) is described as a new web site with cave hyena Crocuta spelaea fossils. The bone-bearing layer was dated to marine isotope stage (MIS) 3 on the basis of the types structure regarding the fauna of big and tiny animals. Finds of plentiful stays of cave hyenas various many years and bones of large herbivores with hyena gnaw marks indicated that the Tip-Tugai Cave was made use of as a hyena den in the Late Pleistocene. Here is the first cave hyena den explained in the Urals.The composition and content of polyphenols in leaves had been examined in Spiraea aquilegifolia Pall. flowers from nine natural communities for the Republic of Buryatia (Western Transbaikalia) by high-performance liquid chromatography (HPLC). At the least 24 substances were recognized in hydroethanolic extracts of S. aquilegifolia makes by HPLC. Among these, three phenol carboxylic acids (chlorogenic, p-hydroxybenzoic, and p-coumaric acids) and six flavonols (hyperoside, isoquercitrin, avicularin, astragalin, quercetin, and kaempferol) had been identified. Hyperoside (2.9-8.2 mg/g), avicularin (3.0-5.8 mg/g), and isoquercitrin (0.8-2.5 mg/g) were the main flavonols present in leaf hydroethanolic extracts. Plants from communities positioned during the north distribution restriction in Western Transbaikalia had been discovered to have higher articles of phenol carboxylic acids (close to the village Koma) and flavonols (close to the village Klyuchi). Flowers from populations situated at the east limitation (near the villages Kusoty and Zagan) revealed the lowest concentration associated with identified phenolic compounds. The contents associated with identified no-cost phenolic acids and flavonols were moderate or full of S. aquilegifolia simply leaves when compared with various other Spiraea species examined, making this crucial to additional research the composition of phenolic substances in S. aquilegifolia.The impact of meteorological facets and anthropogenic polluting of the environment regarding the radial development of the Scots pine Pinus sylvestris L. had been studied as dependent on the distance through the Pechenganickel mining and metallurgical plant (Nikel, Murmansk region). Three (control, buffer, and effect) areas of the air pollution gradient were identified in line with the Liquid biomarker contents of primary polluting elements (S, Ni, and Cu) when you look at the woodland litter. A significant weakening of pine stands had been noticed in the influence zone and related to the combined result of long-term anthropogenic pollution regarding the 1970s and unfavorable weather events of the mid-1980s. Because the emission diminished from 1988 to 2018, the radial increment of P. sylvestris had been seen to improve considerably (by around 44%) into the effect area also to remain very similar within the control and buffer areas.
