title: Isolation of Citreoviridin from Penicillium charlesii Cultures and Molded Pecan Fragments.
abstract: The extraction and systematic fractionation of Penicillium charlesii Smith cultures and contaminated pecan fragments yielded the yellow mycotoxin citreoviridin. Citreoviridin proved acutely toxic to 1-day-old chickens, with an oral 50% lethal dose of 37.5 mg/kg, and showed plant growth inhibition in wheat coleoptiles even at concentrations as low as 10 M. It was toxic to corn seedlings but did not affect young tobacco seedlings.
