Thesis Abstract

**Abstract
** The emergence of antibiotic-resistant bacteria poses a significant threat to public health, necessitating the exploration of alternative antibacterial agents. Natural plant extracts have long been recognized for their potential antimicrobial properties and have been used in traditional medicine for centuries. This study aims to investigate the antibacterial properties of selected natural plant extracts and evaluate their potential for medical applications. The research begins with a comprehensive review of the literature, highlighting the importance of natural products in combating bacterial infections. Various plant species known for their antimicrobial properties are identified and selected for further investigation. The methodology involves extraction of bioactive compounds from these plants using suitable solvents and determination of their antibacterial activity through well-established assays. Results from the study reveal promising antibacterial effects of the natural plant extracts against a range of pathogenic bacteria, including both Gram-positive and Gram-negative strains. The mechanisms of action of these bioactive compounds are explored, shedding light on their potential applications in medical settings. Furthermore, the study investigates the cytotoxicity of the extracts to ensure their safety for human use. The significance of this research lies in its potential to provide new, effective antibacterial agents derived from natural sources. These plant-based alternatives offer a sustainable and eco-friendly approach to combating antibiotic resistance and reducing the reliance on synthetic drugs. By harnessing the power of nature, the findings of this study contribute to the development of novel treatments for bacterial infections. In conclusion, the investigation of the antibacterial properties of natural plant extracts for potential medical applications holds great promise in the field of antimicrobial research. The results underscore the importance of exploring natural sources for drug discovery and highlight the potential of plant-derived compounds as future antibiotics. This study sets the stage for further research and development of plant-based therapies to address the growing threat of antibiotic resistance in healthcare.
