Aflatoxins (AF) and fumonisins (FU) are a major problem faced by poultry farmers, leading to huge economic losses. This experiment was conducted to determine the effects of AF (1 mg/kg of feed) and FU (25 mg/kg of feed), singly or in combination, on the lipid...

Phytochem. Anal. 23(5) , 469-76, (2012)

We report a rapid and accurate method to determine the natural occurrence of aflatoxins (AFs) B1, B2, G1 and G2 in medicinal herbs and the analysis of 174 commercial samples by this method.The aim of the present work is to examine the occurrence of the aflato...
