RESUMO

o-Methoxycinnamaldehyde has been isolated and purified from powdered cinnamon. The compound inhibits the growth and toxin production of mycotoxin-producing fungi. The substance completely inhibited the growth of Aspergillus parasiticus and A. flavus at 100 microgram/ml and A. ochraceus and A. versicolor at 200 microgram/ml. It inhibited the production of aflatoxin B1 by over 90% at 6.25 microgram/ml, ochratoxin A at 25 microgram/ml, and sterigmatocystin at 50 microgram/ml. The substance also displayed a strong inhibitory effect on the growth of five dermatophytoses species, e.g., Microsporum canis (minimum inhibitory concentration, 3.12 to 6.25 microgram/ml). However, no antibacterial effect was observed at concentrations as high as 50 microgram/ml.
