摘要：

The activities of three natural coumarins, xanthotoxin and bergapten (from Ammi majus, Umbelliferae) and psoralene (from Ficus cycomorus, Moraceae), were tested against mycelial growth and aflatoxin production of a toxigenic strain of Aspergillus flavus grown in a rice/corn steep liquor medium. Two other natural chromones, khellin and visnagin (from Ammi visnaga) were also compared. Complete inhibition of aflatoxin release occurred with either xanthotoxin or khellin at 5 mM. The other three compounds also at 5 mM reduced aflatoxin to 12 to 16% of its original concentration. The mould growth was only slightly inhibited by all the compounds used.
