A rapid and sensitive high-performance liquid chromatographic method for the analysis of cis and trans diastereomers of the anticoagulant rodenticide difenacoum has been described. The methodology demonstrates potential for the analysis of diastereomers of related 4-hydroxycoumarin anticoagulants. Separations were achieved

In the liver, it appears that there are two different pathways for vitamin K reduction. One pathway is irreversibly inhibited by coumarin anticoagulant drugs. The other pathway has been shown in the present study to be composed of enzymes that
