A rapid and simplified procedure is proposed for the determination of aflatoxins B1, B2, G1, and G2 in cottonseed products. The method involves extraction of aflatoxins essentially free of lipid contamination by equilibrium extraction with 70% aceton

Aflatoxins were completely resolved as sharp peaks in the order BU-B2-G1-G2 by high-pressure liquid chromatography on a small particle (10 mum) porous silica gel column in 7-13 min (B1 through G2) by a water-saturated chloroform-cyclohexane-acetonitr

Eleven laboratories collaboratively studied a modification of the official final action AOAC method, 26.048-26.056, for determining aflatoxins in cottonseed products. An aflatoxin-negative meal, 6 contaminated meals, 4 contaminated meats (kernels) sa

A precise and sensitive high pressure liquid chromatographic method is proposed for determining aflatoxins B1, B2, G1, and G2 in all types of peanut products. The method is based on acidified aqueous methanol extraction, partition of aflatoxins into

A method for determining aflatoxin in dairy products was modified for eggs, initially by additional cleanup steps. The modified method proved practical for use in survey analyses and was sufficiently sensitive to detect aflatoxin B1 at levels less th
