Abstract : Phytochemicals are biologically active, non-nutritive compounds produced by plants that contribute to their defense mechanisms, coloration, and overall survival, while also providing important health benefits to humans. These secondary metabolites—such as alkaloids, flavonoids, tannins, saponins, terpenoids, and phenolic compounds—are widely known for their antioxidant, anti-inflammatory, antimicrobial, and anticancer activities. Onion (Allium cepa L.) is a commonly consumed vegetable valued for both its nutritional and medicinal properties; however, its leaves are frequently discarded as agricultural waste, despite their potential richness in bioactive constituents. This study seeks to analyze the phytochemical profile, determine the levels of major phytochemical compounds, and evaluate the antioxidant activity of Allium cepa leaves. Quantitative assessment of phytochemicals is crucial for understanding their concentrations, therapeutic relevance, and biological roles, as well as for ensuring quality control and standardization in plant-based products. The results emphasize the significance of onion leaves as an underutilized yet valuable resource with promising applications in functional foods, nutraceuticals, and health-related formulations.

Keywords : Phytochemicals, Quantitative Analysis, Allium Cepa, Hydroponics.
