Abstract
The minicolumn of Holaday and Lansden was modified by increasing the height of neutral alumina and including a layer of anhydrous sodium sulphate. Using this procedure, aflatoxin was detected in 18 of 125 samples of black pepper, red pepper, ginger and turmeric. A few samples of each spice contained aflatoxin, although red pepper and turmeric showed the highest incidence. Aflatoxin B1 quantities ranged from 10 ug/kg to 120 ug/kg when estimated quantitatively by visual comparison with standards on thin‐layer chromatography plates.Keywords
