Go to Editorial ManagerThe Urtica dioica is a flowering plant with long history of use in folk medicine and as a food source. Nettles grow all over the world in mild to temperate climates. The study aimed to determine the antibacterial activity of alcoholic watery extracts of dry leaves of Urtica dioica on some pathogenic microorganisms (E.coli, Staphylococcus. aureus). The Plants were collected in the early time of January from Baghdad. Deride leaves of Uritica were extracted using co-solvent (Water and ethanol) extraction way by Soxhelt apparatus for crude extraction, and use rotary evaporator to obtain power extract. The series dilution was prepared 50%, 25, 12.5w/v that use on Mueller-Hinton agar plates against the St.aureus, E.coli by using well diffusion method then compared with antimicrobial activity of many antibiotics against the same isolates using Kirby-Bauer method. The crude extract of U. dioica showed significant antibacterial effect against some clinically important pathogenic bacteria Staph.aureus : at the concentration 50% the inhibition zone was 20 mm , followed by 25% (14mm) , and12.5%(10mm), and E.coli : at the concentration 50% the inhibition zone was18mm , followed by 25%(12mm) ,and 12.5(8mm) respectively. Based on the obtained results it can be concluded that U. dioica is useful as antibacterial agent in treating infectious diseases.
Objective: Angiogenesis is the formation of new blood vessels from pre-existing vasculature, a basic and tightly controlled biological process. Angiogenesis is essential for tissue regeneration, wound healing, and embryonic development under normal physiological conditions. However, under pathological conditions, dysregulated angiogenesis contributes to several diseases, including cancer, making it an important therapeutic target. Accordingly, natural products, including Capparis spinosa L. have attracted considerable attention as promising anti-angiogenic agents. C. spinosa is rich in bioactive phytochemicals such as flavonoids and phenolic compounds that have been reported to possess anti-angiogenic potential. This study aimed to evaluate the anti-angiogenic and antioxidant activities of Capparis spinosa leaf extracts using complementary ex vivo and in vivo models. Methods: The rat aortic ring anti-angiogenesis assay, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay, and chick chorioallantoic membrane (CAM) assay were carried out in the tissue culture laboratory of the Department of Pharmacology, College of Pharmacy, Al-Nahrain University. Results: The ethanolic extract demonstrated significant inhibition of microvessel outgrowth in the rat aortic ring assay, with an IC₅₀ value of 16.2 µg/mL and reduced neovascularisation in the CAM model, with an inhibition zone of 12±1.83 mm. The extract also exhibited concentration-dependent antioxidant activity in the DPPH assay. Conclusions: The ethanolic extract of Capparis spinosa L. exhibits significant anti-angiogenic and antioxidant activities and represents a promising natural source of compounds capable of modulating angiogenesis and oxidative stress, supporting its potential therapeutic applications.
Background: Volkameria inermis is a medicinal plant traditionally used for its antimicrobial, anti-inflammatory, and antioxidant properties. Owing to the increasing resistance of pathogenic bacteria to conventional antibiotics, there is a growing interest in exploring plant-derived compounds as alternative therapeutic agents. Objectives: The objective of this study was to assess the effectiveness of an ethanolic extract of Volkameria inermis leaves by using an ethanolic solvent that was eighty percent strength. Methods: Samples of leaves were gathered from the center area of Iraq (Al-Musayab), and washed, sorted, and dried in a shaded environment. Through the use of 800 milliliters of 80% ethanol, an extract of Volkameria inermis leaves was created and dried using a rotary evaporator, it was stored in petri dishes that had been sterilized, and one milligram of the extract was dissolved in one milliliter of dimethyl sulfoxide (DMSO). To conduct the antibacterial test using the agar well diffusion technique, the solution was serially diluted to a concentration of 1 mg/ml. The efficacy of an ethanol extract against bacteria as assessed by well diffusion method. Results: When tested against both (Staphylococcus aureus) and (Salmonella typhi) bacteria, the ethanolic extract of Volkameria inermis demonstrated a notable antibacterial effect at a concentration of 500 μg/ml, which resulted in more inhibition zones than the antibiotic ciprofloxacin. Conclusion: The outcomes of this study demonstrated that the Volkameria inermis plant outperformed the drug ciprofloxacin in its antibacterial activity against Staphylococcus aureus and Salmonella typhi.
