Abstract: The present study on comparative phytochemical analysis and antimicrobial activity of selected trees such as Tamarindus indica L. and Quassia indica (Gaertn.) Noot. reveals that, the leaves of both plants possess Carbohydrates, Proteins, Phenols, Amino acids and Alkaloids. When compared to Q. indica (Gaertn.) Noot. T. indica L. leaves possess highest amount of Phenols and Alkaloids. The amount of Carbohydrate, Proteins and Amino acids is higher in Q. indica than that of T. indica. Both the plants have many health benefits and improves the defence mechanism in living system. It is very necessary to introduce new and biologically safe and active drugs eco-friendly in nature and effective as an antimicrobial agent. Due to the presence of significant amount of Phenols and Alkaloids, both the plants possess medicinal and antimicrobial properties. The study also revealed that, the leaves of both plants contain a considerable quantity of Phenolic and Alkaloid compounds that we found to be major contribution to their antibacterial activity. Plants are rich source of secondary metabolites with interesting biological activities. Analyzing phytochemicals with antimicrobial activity in such selected plants will provides an insight into how effective these plants in terms of its medicinal value and also to understand how and why they are effective, which can lead to development of new medicines with lesser side effects.
