Objective: The genus fumaria includes more than 40 species in the world. The aim of this study was to quantify the phytochemical constituents of Fumaria vaillantii L. aerial parts and compare the different methods of extraction. Total phenol, total flavonoid, total alkaloid, ascorbic and organic acids (oxalic, maleic, citric, succinic and fumaric acids) yields were evaluated in terms of the temperature effect, type of solvent and maceration time. Methods: Dried plant samples were extracted by different procedures. Total phenolic, total flavonoid, total alkaloid and ascorbic acid yields were determined by spectrophotometric methods. Also, the organic acid yields were analyzed using high performance liquid chromatography method. Results: With the same extraction method, the natural flora extract was showed more yields of oxalic, maleic and citric acids than the commercial one, while the commercial extract was showed more yields of total phenol, ascorbic, succinic and fumaric acids than the natural flora one. The water-boiled extract was showed more yields of total phenol and total flavonoid. The macerated in ethanol 80% extract was also demonstrated more amounts of total alkaloid and ascorbic acid. Among different aqueous macerated extracts of the commercial sample, as the maceration time increased, total phenol, total flavonoid, oxalic, maleic, succinic, fumaric and ascorbic acids yields decreased. Macerated commercial dried fumitory in double-distilled water for 24 hrs resulted in an extract with the highest possible fumaric acid yield. Conclusion: It can be concluded that both water-boiled and macerated in ethanol 80% extracts can be used as rich sources of total phenolic and total flavonoid, which are considered as the important antioxidants.

Sand mining disturbances and their effects on the diversity of arbuscular mycorrhizal fungi in a riparian forest of Iran

引用

Journal of Arid Land 2017年第6期9卷 837-849页

作者： sareh MORADI BEHBAHANI Mostafa MORADI Reza BASIRI Javad MIRZAEI Department of Forestry Faculty of Natural Resources and Environment B ehbahan Khatam A1-Anbia University of Technology Behbahan *** Iran Department of Forest Science Faculty of Agriculture Ilam University Ilam 69315516 Iran

The major objective of this study was to evaluate the effects of sand mining disturbances on the diversity of arbuscular mycorrhizal fungi（AMF）. In addition, the proportional changes in the diversity of AMF to the distances from riverbanks were assessed. For this purpose, the riparian forest of the Maroon River, Iran was divided into three locations with a 200-meter wide zone in between. Thus, the locations studied were named Distance I（riverbank）, Distance II（intermediate）, and Distance III（farthest from riverbank）. In each of these distances, 10 Tamarix arceuthoides and Populus euphratica of each species were randomly selected. At the same time, soil and root samples were collected from the rhizosphere of the tree species studied. Results indicated that totally 13 AMF species were observed in T. arceuthoides and 19 AMF species were recorded in P. euphratica rhizosphere belonging to 6 genera and 6 families. In these AMF species, Glomus segmentatum, G. geosporum, G. rubiforme, G. nanolumen, G. spinuliferum, Claroideoglomus drummondii, Gigaspora gigantea and Acaulospora paulinae appeared only in P. euphratica rhizosphere, while G. multiforum and Claroideoglomus claroideum were observed only in T. arceuthoides rhizosphere. Moreover, Distance II had the least AMF species both in T. arceuthoides and in P. euphratica rhizospheres, and also the least spore density and root colonization rate. Our results are important in that they provide a list of resistant AMF species that could be used in the conservation of biodiversity.

Effect of SiC content on dry sliding wear, corrosion and corrosive wear of Al/SiC nanocomposites

引用

Transactions of Nonferrous Metals Society of China 2016年第7期26卷 1801-1808页

作者： sareh MOSLEH-SHIRAZI Farshad AKHLAGHI Dong-yang LI School of Metallurgy and Materials Engineering College of EngineeringUniversity of Tehran Department of Chemical and Materials Engineering University of Alberta

The corrosion, corrosive wear and dry sliding wear of nanocomposites, are extremely complicated and involve various chemical, physical anbd mechanical factors. The aim of this work is to investigate the effects of nanosized SiC content on the hardness, dry sliding wear, corrosion and corrosive wear of Al/SiC nanocomposites synthesized by mechanical milling cold pressing and hot extrusion. The corrosion resistance of these composites in 3%NaCl solution was investigated by electrochemical polarization testing and their dry sliding as well as corrosive wear resistance in the same solution was evaluated using a pin-on-disc tester. The microstructures of the samples and their worn surfaces were examined using scanning electron microscopy. It was shown that the dry sliding wear and corrosion resistance of these nanocomposites were improved with the increase of SiC content. It was concluded that due to the lubrication effect of the solution, both the friction coefficient and frictional heat that might soften the material were reduced. In addition, the improved strength of the nanocomposites combined with their better corrosion resistance contributed to their increased corrosive wear resistance, compared with the base alloy. The prominent wear mechanism in the unreinforced alloy was adhesive wear, in the Al/SiC nanocomposites, the wear mechanism changed to abrasive.
