title: Thin layer chromatographic determination of sterigmatocystin in cereal grains and soybeans.
abstract: A method has been developed for determining sterigmatocystin in yellow and white corn, barley, oats, rye, sorghum, brown and wild rice, and soybeans. A partition column packed with activated magnesium silicate was used for cleanup. Averaged recoveries are 104% in white corn, 114% in rye, 100% in oats, 134% in brown rice, 96% in barley, 105% in sorghum and wild rice, and 92% in soybeans. The limit of sensitivity is 50 mug/kg for any of these commodities.
