Acmella Essential Oil: A Potent Antibacterial Agent Against a Clinical Isolate of Moraxella sp.

Abstract

The flowers of Spillanthes acmella (Asteraceae) Murr., was subjected to hydrodistillation in a Clevengers apparatus. From the GC-MS data, 16 peaks were observed. The highest peak in the form of percentage (area) was 51.08. Further, the hydrodistillate of Spilanthes was studied for its antibacterial efficacy against a clinical bacterial isolate, Moraxella sp.. Both the qualitative and quantitative assays were correlated. The hydrodistillate was observed to be cidal in its inhibitory concentrations. The optical microscopic studies more over the Scanning Electron Microscopic (SEM) studies were illustrative about the cellular disruption activity of the herbal hydrodistillate.
