Abstract
This study explores the phytochemical diversity of a selection of medicinal plants, aiming to identify and quantify their bioactive compounds and assess their potential pharmacological properties. Ten widely used medicinal plants, including Mentha piperita, Curcuma longa, Withania somnifera, and Echinacea purpurea, were selected for analysis based on their therapeutic applications. The plants were subjected to solvent extraction, followed by qualitative and quantitative analysis using High-Performance Liquid Chromatography (HPLC), Gas Chromatography-Mass Spectrometry (GC-MS), and UV-Vis Spectroscopy. The study examined the concentrations of key phytochemicals such as alkaloids, flavonoids, terpenoids, and glycosides across different plant species, and their pharmacological activities, including anti-inflammatory, antioxidant, antimicrobial, and adaptogenic effects. Results revealed significant variations in the chemical profiles of the plants, influenced by geographical and environmental factors. The findings highlight the complex nature of phytochemical composition and underscore the importance of considering these factors in the development of plant-based therapeutic agents. This research contributes to the growing body of knowledge regarding the therapeutic potential of medicinal plants and provides a comprehensive understanding of their bioactive compounds, aiding in future drug discovery and the use of natural remedies.
