An object of the present invention is to provide an aflatoxin production inhibitor that inhibits aflatoxin production specifically and efficiently, is highly safe, and is practical, and an efficient production method thereof; and a method for controlling aflatoxin contamination that uses the aflatoxin production inhibitor.
Specifically, the present invention relates to an aflatoxin production inhibitor that includes at least one of a dioctatin represented by the following formula (I) and a derivative thereof, as an active ingredient:
where, in the formula (I), R represents one of hydrogen and a methyl group.
The present invention also relates to a method for producing an aflatoxin production inhibitor in which dioctatin is prepared: by a method including culturing a dioctatin-producing microorganism, and at least one of separating and purifying dioctatin from a culture obtained, by centrifugal liquid liquid partition chromatography; or by chemical synthesis. Further, the present invention relates to a method for controlling aflatoxin contamination that includes using the aflatoxin production inhibitor to thereby inhibit aflatoxin production by an aflatoxin-producing microorganism.
