A COMPARATIVE STUDY OF ANTIMICROBIAL EFFICACY OF CINNAMOMUM ZEYLANICUM LEAF OIL AND CINNAMOMUM TAMALA LEAF OIL

Abstract

Cinnamomum has a wide range of medicinal properties and has been used from ancient times due to its medicinal properties. Cinnamomum is an aromatic plant that belongs to the family Lauraceae and has antimicrobial, antioxidants, antidiabetics, anti-inflammatory, and antiseptics properties. This comparative study is conducted to evaluate the antimicrobial efficacy of essential leaf oil of C.zeylanicum and C.tamala against a broad range of tested bacteria. Hydrodistillation is used to produce the essential leaf oil by using the Clevenger apparatus. The antibacterial activity was tested against V.cholerae, Alcaligenes xylosoxidans, Staphylococcus aureus, Rhizobium trifolii, Klebsiella pneumoniae, Proteus vulgaris, Shigella dysenteriae, and Streptomyces cinerochromogenes by agar diffusion plate method and determining the anti-microbial activity of essential leaf oil by observing the inhibition zone. Results indicated that C.zeylanicum and C.tamala leaf extract have a potential antibacterial property and thus could be used in wide applications after evaluating the potential efficacy of essential leaf oil for human use.
