title: The effect of pyrrolizidine alkaloids (Senecio vulgaris) on the liver mixed-funcion oxidase system.
abstract: A model system to detect the toxicity of pyrrolizidine alkaloids (PAs) was explored. Using the liver S-10 fraction, the effect of PAs on aniline hydroxylase and aminopyrine N-demethylase was examined. PAs were toxic to the aminopyrine N-demethylase enzyme system while exerting no toxicity on the aniline hydroxylase enzyme system.
