Abstract

The inhibition of Aflatoxin production from Aspergillus parasiticus strain NRRL 2999 was investigated using ethanol extracts of Aframommon danielli flower at concentrations of 250ìg/g, 500ìg/g, 750ìg/g and 1000ìg/g with whole wheat bread as a substrate. Aspergillus parasiticus grew abundantly on whole wheat bread; growth on samples containing 250ìg/g and 500ìg/g extracts were scanty and those of 750ìg/g and 1000ìg/g were not visible. The percentages
aflatoxin (B1 + G1) inhibitions of the flower extract were 25.2% (250ìg/g), 43.5 (500ìg/g), 65.2% (750ìg/g) and 70.2% (1000ìg/g). The percentage inhibition for Tioconazole (100ìg/g) was 88%. The result showed that Aframommon danielli flower ethanol extract can prevent mould growth
and aflatoxin production in foods.
