In Vitro Antibacterial Activities of Various Ethanolic Medicinal Plant Extracts Against Some Human Pathogenic Bacteria
2020
Samir K. Ali | Ghorbat S. Ali | Berivan Abdulrahman Abdullah
The widespread use of antibiotics often causes increase in the bacterial drugs resistance and causes many side effects in humans. Medical plants have antimicrobial effects against most pathogenic bacteria and can serve as harmless replacement to antibiotics. The aim of this study was to assess the antibacterial effect of five medicinal plant prevailed in Kurdistan region namely; Cinnamon (Cinnamomum cassia (L.) D.Don), Nigella (Nigella sativa L.), Allium (Allium hirtifolium Boiss.), Carrot (Daucus carota L.), and Fennel (Foeniculum vulgare Mill.) against pathogenic Gram positive bacteria (Staphylococcus aureus), and pathogenic Gram negative bacteria (Salmonella typhi and Escherichia coli). The evaluation of antibacterial activity for these plant extracts was carried out using agar-well diffusion method. Results showed that minimum inhibitory concentration (MIC) of A. hirtifolium against tested bacterial isolates were (25 mg/mL), the lowest MIC values for S. aureus were (25 mg/mL) observed with C. cassia, N. sativa and F. vulgare ethanolic extracts and the lowest MIC of D. carota against bacterial isolates were (50 mg/mL), Also, it was observed that S. aureus was more sensitive than S. typhi and E. coli to plant extracts. The ethanol plant extracts had potential antibacterial activities. However, further studies are required to identify the active compounds which could be used for the preparation of new antimicrobial agents and control the bacterial infectious diseases.

In this study, antioxidant, oxidant and oxidative stress index of Thymbra spicata L. collected from Duhok (Iraq) region were determined. The aerial parts of the plant were extracted with ethanol. Rel Assay Diagnostics kits were used for detect TAS, TOS and OSI values. As a result of the studies, it was determined that TAS value of plant extract was determined 8.399±0.102, TOS value was 6.530±0.115 and OSI value was 0.078±0.001. As a result, it was determined that T. spicata has high antioxidant potential and in this context, can be used as a natural resource.

Falah Saleh Mohammed | Hasan Akgül
The present study was conducted in the province of Duhok (Northern Iraq) between 2011-2012. The study attempted to determine the use of certain indigenous and cultivated plants in Duhok province in alternative medicine and place of these plants in systematics. Thus, 49 taxa in 27 genera and 46 species were identified. Two taxa belonged to Coniferophyta, one belonged to Pteridophyta and 46 belonged to Magnoliophyta dividions. It was determined that the family with the most numerous taxa in the region was Rosaceae with 5 taxa, followed by the Fabaceae and Lamiaceae family with 4 taxa and Apiaceae, Asteraceae, Cucurbitaceae and Poaceae family with 3 taxa each. Certain ethnobotanical features of the identified taxa, such as systematics, habitats, flowering times, local names and alternative uses in medicine were presented.

The study was conducted in Mahanawiyah district in AL-Qadisiya Province, Iraq to identify the training needs of rice farmers. 125 farmers were selected as a random sample. A list of 8 major areas of training needs in relation to rice cultivation practices was prepared whiten 50 sub-area. Scores were measured on four-point scale. The primary data were collected using a pre-tested structured interview schedule by conducting personal interview. Findings revealed that majority of the farmers had medium level of training needs. Weed management, disease and pests control, seed and seedling were the top most training needs of the farmers and the least training need was Land preparation. The variables educational attainment, area cultivated with rice, and annual revenue from rice cultivation had positive and significant association with the training needs.
