IN VITRO ASSESSMENT OF ANTIMICROBIAL AND ANTIOXIDANT ACTIVITIES OF EXTRACTS OF YEMENI FAGONIA SCHWEINFURTHII HADIDI

Abstract

Background: Antioxidant and antimicrobial properties of plant extracts are attributed to bioactive components derived from medicinal plants. This study inspected into the antimicrobial and antioxidant effects of extracts from Fagonia schweinfurthii Hadidi aerial portions. Method: Several solvents, including n-hexane, ethyl acetate, and methanol, were utilized sequentially to extract secondary metabolites from F. schweinfurthii aerial parts. Antimicrobial activity was evaluated using the well diffusion method and broth serial dilution, whilst antioxidant activity was evaluated using the 2, 2-diphenyl-1-picrylhydrazyl radical scavenging method. Results: The findings exposed that the studied fungal strains (Candida albicans and Trichophyton rubrum) were resistant to all plant extracts. F. schweinfurthii methanol and ethyl acetate extracts demonstrated inhibitory effects on Gram-positive and Gram-negative tested bacteria with minimum inhibitory concentration between 2.5 and 20 mg/ml. In addition, the most sensitive bacterium was Proteus vulgaris, with an inhibitory concentration (2.5 and 5 mm). While the most resistant bacterium was Staphylococcus epidermidis. Due to the physical and chemical properties of the solvents, different extracts of F. schweinfurthii aerial parts exhibited diverse antioxidant capabilities in the antioxidant activity experiment. Methanol and ethyl acetate extracts exhibited IC50 values of 236 ± 0.2µg/ml and 359.4± 0.6µg/ml, respectively. Conclusion: According to the findings of this study, the aerial portions of F. schweinfurthii could be considered a possible source of natural antioxidants as well as a valuable source of antibacterial agents against bacteria that cause ear infections.

The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.
