Abstract

Aspergillus niger is a highly virulent and environmentally resistant fungus that often causes spoilage in fruits and vegetables and can also cause disease in humans. Therefore, there is a need to find natural extracts to combat this fungus. This research found that cinnamon bark essential oil has significant antifungal activity against Aspergillus niger. GC-MS analysis of cinnamon bark essential oil revealed 15 volatile compounds, with cinnamaldehyde being the dominant component. Antifungal activity was tested using the disc diffusion method and dilution technique to determine the Minimum Inhibitory Concentration (MIC) and Minimum Fungicidal Concentration (MFC). The results showed that cinnamon bark essential oil exhibited a large inhibitory zone of up to 12.29 mm, demonstrating significant antifungal activity against A. niger. These results indicate that cinnamon bark essential oil, with cinnamaldehyde as the main component, is a highly potent natural extract for preventing fungal infections.

Keywords

Cinnamon bark essential oil, Aspergillus niger, GC–MS analysis, Antifungal activity, Natural extract.
