摘要：
The effect of five different concentrations (2, 4, 6, 8 and 10 mg ml(-1)) of an aqueous extracts of Lupinus albus, Ammi visnaga and Xanthium pungens were tested on growth and aflatoxin production by Aspergillus flavus in a chemically defined medium. All the plants inhibited mycelial growth and aflatoxin formation. The inhibitory effect was proportional with the applied concentration. Growth and aflatoxin production appeared to be correlated processes. The nature of the plant extract also affected the ratio of B-1 to B-2, and there was no correlation between the inhibition of aflatoxins or growth of the fungus and the resultant B-1: B-2 ratio.
