Osteoarthritis (OA) is one of the most common articular disorders. Many patients do not respond to acetaminophen and non-steroidal anti-inflammatory drugs (NSAIDs), the mainstay of pharmacotherapy for knee OA. The plants Elaeagnus angustifolia and Boswellia thurifera have anti-inflammatory and analgesic properties. This study aimed to evaluate the effect of E. angustifolia alone and in combination with B. thurifera compared with ibuprofen in patients with knee osteoarthritis. In a randomized double-blind controlled clinical trial, 75 patients with knee OA were randomly and equally assigned to one of three groups Elaeagnus (n = 23), Elaeagnus/Boswellia (n = 26), and ibuprofen (n = 26) to receive the capsules of Elaeagnus, Elaeagnus/Boswellia, and ibuprofen, respectively, three times daily with meals for 4 weeks...

A flash extraction method was used to isolate Elaeagnus mollis oil (EMO). The optimal extraction parameters, sample/solvent ratio and extraction temperature, were determined to be 1:10 (g/mL) and 40°C, respectively. Especially, the extraction yield reached 49.30% when the extraction time was as short as 2 min. No obvious difference was observed in fatty acid composition, iodine value, saponification number, total phenolic content and tocopherol content between flash-extracted EMO and Soxhlet-extracted EMO, but their physicochemical values were lower than those of cold-pressed EMO...

Invasive species are a significant threat to global biodiversity, but our understanding of how invasive species impact native communities across space and time remains limited. Based on observations in an old field in Southeast Michigan spanning 35 years, our study documents significant impacts of habitat change, likely driven by the invasion of the shrub, Elaeagnus umbellata, on the nest distribution patterns and population demographics of a native ant species, Formica obscuripes. Landcover change in aerial photos indicates that E...

Elaeagnus angustifolia L., which is commonly known as oleaster or Russian olive, is a deciduous plant from Elaeagnacea family. This plant can tolerate and survive a wide variety of environmental conditions. Different parts of E. angustifolia plant, especially the fruits and flowers, have been used traditionally in treating a variety of common illnesses such as nausea, cough, asthma, fever, jaundice, and diarrhea. The use of fruit powder and extract of E. angustifolia L. have shown to be effective in alleviating pain in patients with rheumatoid arthritis and also in reducing the healing time of wounds in injured person...

The leaves of Elaeagnus pungens were extracted and successively purified by a set chromatographic techniques. The structures of the obtained constituents were elucidated on the basis of spectroscopic methods including 1D/2D NMR and high resolution-MS. One new flavonoid glycosides, kaempferol 3-O-β-d-glucopyranosyl-(1 → 3)-α-l-rhamnopyranosyl-(1 → 6)-[α-l-rhamnopyranosyl(1 → 2)]-β-d-galactopyranoside-7-O-β-d-glucopyranoside (1), along with five known compounds (2-6) were isolated and identified. The MTT assay in vitro showed that the isolated flavonol glycosides have no proliferating activity, suggesting no aggravating impact on the increased airway smooth muscle cells...

Strain EuI1c(T) is the first actinobacterial endophyte isolated from Elaeagnus umbellata that was shown to be infective on members of Elaeagnaceae and Morella but lacking the ability to form effective root nodules on its hosts. The strain can be easily distinguished from strains of other Frankia species based on its inability to produce vesicles, the specialized thick-walled structures where nitrogen fixation occurs. Chemotaxonomically, strain EuI1c(T) contains phosphatidylinositol, diphosphatidylglycerol, two glycophospholipids and phosphatidylglycerol as phospholipids...

Before the establishment of pure cultures, the species Frankia alni, 'Frankia casuarinae' and 'Frankia elaeagni' were proposed to encompass all causal agents of the nitrogen-fixing root nodules of dicotyledonous plants from the genera Alnus, Casuarina or Elaeagnus. The sole Frankia species with a validly published name, the type species F. alni, was described by Woronin (1866) as present in the root of alder. Until now no type strain has been designated for F. alni, even though the absence of a type strain has seriously inhibited the application of modern taxonomic methods to the genus Frankia...

Targeted Illumina sequencing of nitrogenase reductase (nifH) gene fragments and analyses of pair-end reads through a modified QIIME pipeline were used to assess the diversity of the actinomyceteous genus Frankia in three soils. Soils were vegetated with host or non-host plants, and included locations in Illinois (ABA, host), Colorado (CoMt, non-host), and Wisconsin (FMWI, non-host). After filtering, seven unique sequences were recovered for soil ABA, six for CoMt, and four sequences for FMWI. These sequences were included in a Bayesian topology anchored by published sequence data from pure cultures of Frankia...

In this research, extraction optimization, preliminary characterization and immunological activities in vitro of polysaccharides from Elaeagnus angustifolia L. pulp were investigated. A response surface methodology (RSM) with a Box-Behnken design (BBD) was used to optimize the extraction process. The maximum EAP yield was 9.82±0.38%, which is in good agreement with the predicted value (9.93±0.24%). Two homogeneous polysaccharides, EAP-1a and EAP-1b with molecular weights of 8.70kDa and 4.39kDa respectively, were prepared by DEAE-52 cellulose and Sephadex G-100 columns and characterized by HPLC, HPGPC, and FT-IR...

In the present study, zinc oxide nanoparticles (ZnO NPs) were rapidly synthesized at room temperature by treating zinc acetate dihydrate with the flower extract of Elaeagnus angustifolia (Russian olive). The formation of ZnO NPs was primarily confirmed by UV-visible absorption spectrum in the range of 250-700nm. XRD analysis and DLS particle size analyzer revealed the size of ZnO NPs. The FTIR spectrum revealed the presence of phytochemicals in the flower extract mediated ZnO NPs. Moreover, the morphology of the ZnO NPs was determined using SEM...

Osteoarthritis (OA) is one of the most common musculoskeletal disorders all over the world. Available anti-arthritic medications have only partial efficacy and their long-term use is associated with adverse events. Elaeagnus Angustifolia (EA) is a medicinal plant with analgesic and anti-inflammatory properties. The present study evaluated the impact of two doses of EA extract compared with ibuprofen on the severity of disease in patients with knee OA. This study was designed as a randomized, double blind, active-controlled and parallel group trial...

The physicochemical properties, fatty acid profiles, content of tocopherol and sterol of the oils extracted from the nuts of Elaeagnus mollis Diels grown in different regions of China were studied in this work. The results indicated that the Elaeagnus mollis Diels nut oils contained about 0.2% sterols and the tocopherol contents were in the range of 119.6-128.6mg/100g. The nut oils were all rich in unsaturated fatty acids, especially oleic acid and linoleic acid. Furthermore, the main triacylglycerols species of the nut oils were all dilinoleoyl-monoolein (LOL), dioleoyl-monolinoleoyl (OLO) and trilinoleate (LLL)...

Quantitative PCR (qPCR) was used to follow population dynamics of indigenous Frankia populations in bulk soil, in leaf-litter-amended soil and in the rhizosphere of Alnus glutinosa or Casuarina equisetifolia at 2 matric potentials representing dry and wet conditions in soil microcosms. Analyses revealed between 10- and 100-fold increases of Frankia populations within the incubation period of 12 weeks independent of treatment. Numbers were generally higher under dry conditions and in the rhizosphere, with that of C...
