Antimicrobial activity of Cinnamaldehyde from Methanolic extracts of Cinnamon on Klebsiella pneumoniae & Candida albicans

Abstract

Cinnamaldehyde was extracted from cinnamon by steam distillation. The in vitro antimicrobial activity of Cinnamaldehyde from cinnamon bark has been evaluated against Klebsiella pneumoniae and Candida albicans. Methanolic extract of cinnamon was used. Methanol was the best solvent for Cinnamaldehyde. The inhibition zone for Klebsiella pneumonia was 10mm and for Candida albicans was 4mm. The solvent showed the zone of 3mm on Klebsiella pneumonia and no inhibition on Candida albicans. From the results it concludes that Cinnamaldehyde from Cinnamon species shows antimicrobial activity.
