Antimicrobial activity and Chemical composition of leaf oil in two varieties of Piper betle from northern plains of India

摘要

Leaf essential oil of Piper betle variety bangladesi and deswari, obtained by steam distillation were assigned for their antimicrobial potential against a set of pathogenic microbes. Oil from the leaves of Piper betle variety bangladesi and deswari was found active against the selected strains of bacteria and fungi. GC-GC MS analysis of the Piper betle variety bangladesi and deswari oil resulted in the identification of twenty five and thirty five compounds representing 85.41% & 86.11% respectively. Major components identified (eugenol, a selinene, a farnesene, β selinene, methyl eugenol, germacerene D) were same in both the oils beside safrole which was not found in the leaf oil of Piper betle variety bangladesi. The two essential oils showed antibacterial activity against Staphylococcus aureus, Staphylococcus epidermidis, Klebsiella pneumoniae and antifungal against Candida albicans, Candida rugosa, Saccharomyces cerevisiae, Aspergillus niger and Aspergillus flavus.
