The hazardous nature of aflatoxins to human and animals necessitate the need
for establishment of control measures. The objective of this study was to
evaluate the inhibition of growth and aflatoxin production of Aspergillus
flavus strain (ATCC 16872) by various essential oils in Yeast Extract
Sucrose (YES) growth media at 25°C. Essential oils of basil, fennel,
coriander, caraway, peppermint and rosemary were tested for their effects on
mycelial growth and aflatoxin production. Aflatoxin B1 production was
determined by high performance liquid chromatography (HPLC). The findings of
this study revealed the antifungal efficacy of the all tested essential
oils. The extent of inhibition of fungal growth and aflatoxin production was
dependent on the type and concentration of essential oils used. The complete
inhibition of Aspergillus flavus growth was observed at 1000 ppm
concentrations of essential oils of basil, coriander, caraway and rosemary.
While, essential oils of basil and coriander showed marked inhibition of
aflatoxin B1 produced by Aspergillus flavus at all concentrations
tested 500,750 and 1000 ppm.
