Isolation, Structural Characterization and Identification of Major Constituents in Ephedra foliata Naturally Growing in Iraq by TLC, GC-MS and UPLC-ESI-MS/MS
...Show More Authors

Abstract:

   The aerial part of Ephedra foliata Family Ephedraceae have long been used in traditional medicine and now Ephedra species have medicinal, ecological, and commercial value. The variety of pharmacological actions of this plant is due to its chemical constituents. Ephedrine and
related alkaloids; are the newly potential medicinal value of Ephedra supplements for weight loss or performance improvement. Other pharmacological actions like antibacterial and antifungal effects of the phenolic acid compounds, the immunosuppressive action of the polysaccharides, and the antitumor action of flavonoids. The genus of this plant wildly distributed throughout asia, america, europe, and north africa.
 Aim of study:  this study is to screen the phytochemical constituents due to the importance of pharmacological actions of this plant.

Methods:  the aerial part of E. foliata was macerated in 80% ethanol for 9 days and fractionated by n-hexane, chloroform, ethyl acetate, and n-butanol. The n-hexane, chloroform, n-butanol fractions, and isolated compounds were analyzed by GC-MS, TLC, UPLC ESI MS/MS.

Results and discussion: The various chromatographic and spectroscopic results indicate  the presence of a different type of phytochemicals like ephedrine, 6hka, vicenin 2 and quercetin 3-sophoroside-7-rhamnoside.

The Functions of Onomatopoeia in Modern English and Arabic Poetry: A Study in Selected Poems by Lawrence and al-Sayyab
...Show More Authors

Onomatopoeia has always been a functional poetic device which enjoys a high sound significance in the poetry of many languages. In modern English and Arabic poetry alike, it proves to be vital and useful at different levels: musical, thematic and at the level of meaning. Still, the cultural difference looms large over the ways it is employed by the poets of each. The present paper investigates the employment of onomatopoeia in the poetry of D. H. Lawrence (1885-1930) and Badr Shakir al-Sayyab (1926-1964) who are chosen due to the importance they enjoy in modern English and Arabic poetry and the richness of their poems in onomatopoeias. The conclusions reached at are in a sense related to cultural differences which govern the use of onomato

Fixing the relationship of the syntactic concept and structural scheme of sentences: A Linguistic and Cultural Approach.
...Show More Authors

The article defines the relationship between the syntactic concept and the structural scheme of a sentence in modern scientific research from the standpoint of the linguistic cognitive approach; the definitions of the concepts “syntactic concept” and “structural scheme of a sentence” have been represented; a linguocognitive approach to the study of the structural schemes of a sentence through the prism of syntactic concepts has been proposed, which gives a new solution to the problem of the interaction of syntax and semantics; the mental and linguistic levels have been identified, as well as the principles of their interaction in the process of analysing the sentence.

The Effectiveness of a Structural Theory- based Training Program in Enhancing Arabic Language Teachers’ Teaching Practices and their Tendencies towards Structural Teaching: مريم بنت حسن البلوشي، ريا بنت سالم المنذري، علي مهدي كاظم
...Show More Authors

The study aims to identify the effectiveness of a structural theory-based training program in enhancing the teaching practices of Arabic language teachers teaching grade ten in South Al Batinah in Sultanate of Oman. The study used the quasi-experimental design, and the sample consisted of 40 male and female teachers. To achieve the objectives of the study, a training program, an observation form and a measurement tool of teachers’ tendencies towards a structural teaching were made. The program was implemented with an experimental group of 20 female and male teachers in the first semester of the academic year 2018/2019. The study has found that there is a statistically significant difference between the average grades before and after i

A New Method for the Isolation and Purification of Trigonelline as Hydrochloride from Trigonella foenum-graecum L.
...Show More Authors

Separation of Trigonelline, the major alkaloid in fenugreek seeds, is difficult because the extract of these seeds usually contains Trigonelline, choline, mucilage, and steroidal saponins, in addition to some other substances. This study amis to isolate the quaternary ammonium alkaloid (Trigonelline) and choline from fenugreek seeds (Trigonella-foenum graecum L.) which have similar physiochemical properties by modifying of the classical method. Seeds were defatted and then extracted with methanol. The presence of alkaloids was detected by using Mayer's and Dragendorff's reagents. In this work, trigonilline was isolated with traces of choline by subsequent processes of purification using analytical and preparative TLC techniques.

Chemical Synthesis and Characterization of Conducting Polyaniline
...Show More Authors

     The polyaniline powder was chemically manufactured by direct oxidation of aniline. The resulting polymer was characterized by the results of optical, measurements by (FT-IR) spectroscopy, we have detected some of the absorption peaks located at 3498, 2858 cm-1, which correspond N-H vibrations, and C-H expansion of the aromatic ring respectively as well as stretching vibrations of quinoid ring have been observed. Structural properties, such as the surface topography using an atomic force microscope (AFM), and Surface composition by (SEM) have been studied. The structure of some pellets of polyaniline powder have been examined by using analytical X-ray diffraction technique, the pattern of obse
