Fig. 1From: Efficacy of cinnamon bark oil and cinnamaldehyde on anti-multidrug resistant Pseudomonas aeruginosa and the synergistic effects in combination with other antimicrobial agentsTLC chromatogram of cinnamon bark oil. TLC fingerprints of essential oils were developed by toluene and ethyl acetate with ratio of 93:7 v/v and visualized under UV light 254 nm (left), 366 nm (center) and visible light (right) (a). Bioautographic assay against P. aeruginosa was demonstrated (b). Lane A, cinnamon bark oil; lane B, eugenol; lane C, cinnamaldehyde.
