Abstract

A plant with as diverse a role as Peppermint leaves is a versatile resource for all forms of life. The plant extracts have active compounds in the form of alkaloids, glycosides, lactones and steroids. All these active compounds have immunomodulatory and physiological roles of different types, thereby demonstrating the diverse versatility of the plant. Studies need to be conducted with aspects of how the active compounds actually interact with the living systems and affects the structure-function relationships Aqueous extract of Peppermint leaves were extracted by aqueous method. In the qualitative phytochemical testing presence of various secondary metabolites were found in aqueous extract of Peppermint leaves were Alkaloid, Flavonoids, Tannins and Saponin. In the quantitative analysis carbohydrate was found in) Peppermint leaves sugar conc. is found (470 μg/ml). Antimicrobial activity was also quite good, in Peppermint leaves respectively against Escherichia coli and Staphylococcus aureus.
