Abstract

lstražen je utjecaj dehidracetne kiseline (DHA) i njezinih novosintetiziranih analogona, 4-hidroksi-6-(p-tolil)-3-(p-toluil)-2H-piran-2-ona (DHT) i 5-bromo-4-hidroksi-6-(p-tolil)-3-(p-toluil)-2H-piran-2-ona (BrDHT). na rast aflatoksinogene plijesni Aspergillus parasiticus NRRL 2999 i nakupljanje aflatoksina. Koncentracije DHA i DHT od 3.0 i 6.0 µ,M stimuliraju. a koncentracije više od 30.0 µ,M tih spojeva inhibiraju rast plijesni i proizvodnju aflatoksina. U pokusima s niskim koncentracijama spoja BrDHT. reduciran je rast plijesni do 70%. a koncentracije aflatoksina 81 i 01 bile su reducirane do vrijednosti od 85 odnosno do 90% u odnosu na kontrolne pokuse.
