Phytochemical and Pharmacological Study of Valepotriates in Valeriana officinalis L. F.Valerianeceae Cultivated in Iraq
...Show More Authors

This study concerned with phytochemical investigation and methods of extraction and separation of active constituents from Valeriana officinalis plant cultivated in Iraq. Due to the large number of active constituents in Valeriana officinalis, it was necessary to make analytical study of its constituents to determine the chemical nature of these constituents and then determine the main classes (terpenes and iridoids) using chemical reagents specific for each class. Different organic solvents like ethanol (70%) used in soxhlet apparatus and hexane, ethyl acetate and methanol were used separately to extract the main active constituents by maceration. Through comparison between these solvents using thin layer chromatography (TLC), it has been found that hexane was best suited to extract most of the active constituents from the plant by maceration method. Analytical study showed that terpens was separated and purified using preparative TLC and preparative HPLC. Identification of isolated component (valtrate) from roots of plant was obtained using HPLC and PHPLC also depending on some material-specific constants such as infrared spectroscopy (FTIR). Results of analysis showed that Valeriana officinalis cultivated in Iraq is a good source of many constituents with different important pharmacological activities. The pharmacological study showed that the total organic plant extract has sleep induction effect when injected I.P. to experimental mice.

 Key wards:  Valeriana officinalis, Valepotriate, Insomnia.

The Structural and Stress Analysis of Hemrin North Structure, North of Iraq.
...Show More Authors

  The study focused on the results of first paleostress from thrust fault slip data on Tertiary age of Hemrin North Structure, North of Iraq. The stress inversion was performed for fault slip data using an improved right dihedral model, and then followed by rotational optimization (Georient Software). The trend of the principal stress axes (σ1, σ2 and σ3) and the ratio of the principal stress differences (R) show the main paleostress field is NE-SW compression regime. As well as using Lisle graph and Mohr diagram to determine the magnitudes of palestress.  The values paleostress of the study area were σ1=1430 bars, σ2=632 bars and σ3=166 bar. The large magnitudes of the primary stress axes could be attributed to active tecto

...Show More Authors

The importance of this research is to clarify the nature and the relationship between the indicators of financial policy and banking stability in Iraq, as well as to find a composite index reflects the state of banking stability in Iraq in order to provide an appropriate means to help policymakers in making appropriate decisions before the occurrence of financial crises.
