Thesis Abstract

Abstract
The increasing interest in natural antioxidants derived from plant sources has driven the need to evaluate and quantify their antioxidant activity. This study focuses on the determination of antioxidant activity of plant extracts using spectrophotometric assays, aiming to contribute to the understanding of the potential health benefits associated with these natural compounds. The research methodology employed various spectrophotometric techniques to assess the antioxidant capacity of selected plant extracts, providing valuable insights into their free radical scavenging abilities. The study involved a comprehensive literature review to establish a solid foundation for understanding the significance of antioxidants in human health and disease prevention. Chapter One introduces the research topic, providing background information on antioxidants, the problem statement, objectives, limitations, scope, significance of the study, and a detailed structure of the thesis. Chapter Two presents a thorough literature review covering ten key aspects related to antioxidants, plant extracts, and spectrophotometric assays. This review sets the stage for the research methodology discussed in Chapter Three, which outlines the experimental design, sample preparation, spectrophotometric analysis procedures, data collection methods, and statistical analysis techniques employed in this study. Chapter Four delves into the discussion of findings, presenting and analyzing the results obtained from the spectrophotometric assays conducted on the plant extracts. The discussion includes comparisons between different plant extracts, the correlation between antioxidant activity and phytochemical composition, and the implications of the findings in the context of natural antioxidant sources. Finally, Chapter Five offers a conclusive summary of the research outcomes, highlighting the key findings, implications for future research, and concluding remarks on the significance of determining antioxidant activity in plant extracts using spectrophotometric assays. This thesis contributes to the existing body of knowledge on natural antioxidants and their potential health benefits. The findings from this study offer valuable insights into the antioxidant properties of plant extracts, paving the way for further research on harnessing these natural compounds for therapeutic and preventive purposes. By employing spectrophotometric assays to evaluate antioxidant activity, this study provides a robust methodology for assessing the efficacy of plant-derived antioxidants, which can have significant implications for the development of functional foods, nutraceuticals, and pharmaceutical products aimed at promoting human health and well-being.
