Aspergillus flavus and parasiticus associated with almonds were isolated and three different culture media were used to qualitatively measure aflatoxin production by Aspergillus via UV light (365 nm). Commercially rosemary essential oil was tested to determine their influence on growth and aflatoxin production in A. flavus and A. parasiticus by performed through high-performance liquid chromatography (HPLC). The results showed that the tested essential oils caused highly significant inhibition of fungal growth and aflatoxin production in A. flavus and A. parasiticus.
