Thesis Abstract

Abstract
The emergence of antibiotic-resistant bacteria presents a significant global health challenge, underscoring the urgent need to explore alternative sources of antimicrobial agents. This thesis investigates the antimicrobial properties of plant extracts as a potential avenue for drug development. The study focuses on a diverse range of plant species known for their traditional medicinal uses, with the aim of identifying novel bioactive compounds with potent antimicrobial activity. The research methodology involves a comprehensive literature review to establish the current knowledge on the antimicrobial properties of plant extracts, followed by laboratory experiments to evaluate the efficacy of selected plant extracts against a panel of pathogenic bacteria and fungi. The findings from these experiments are discussed in detail, highlighting the potential of plant-derived compounds as effective antimicrobial agents. Chapter One provides an introduction to the research topic, outlining the background of the study, problem statement, research objectives, limitations, scope, significance, structure of the thesis, and definition of key terms. Chapter Two comprises a detailed literature review covering ten key areas related to the antimicrobial properties of plant extracts, including the mechanisms of action, bioactive compounds, and previous research findings. Chapter Three presents the research methodology, which includes the selection and preparation of plant extracts, microbial culture techniques, antimicrobial assays, data analysis methods, and quality control procedures. The chapter also discusses ethical considerations and experimental design to ensure the validity and reliability of the study results. In Chapter Four, the results of the antimicrobial assays are extensively discussed, highlighting the potency of specific plant extracts against various pathogens. The discussion delves into the mechanisms of antimicrobial action, synergistic effects of plant combinations, and potential applications in drug development. Furthermore, the chapter addresses any deviations from expected outcomes and suggests areas for further research. Finally, Chapter Five summarizes the key findings of the study and provides a comprehensive conclusion on the potential of plant extracts as a valuable source of antimicrobial agents for drug development. The thesis concludes with a reflection on the implications of the research findings, recommendations for future studies, and the broader impact of harnessing plant-derived compounds in combating antibiotic resistance. In conclusion, this thesis contributes to the growing body of knowledge on the antimicrobial properties of plant extracts and underscores their potential as a promising source of novel antimicrobial agents for future drug development efforts. The findings of this study offer valuable insights into the untapped therapeutic potential of plant-derived compounds and pave the way for further exploration in the field of natural product-based drug discovery.
