Excretion and tissue distribution of radioactivity from aflatoxin B1-14-C in rats.

Excretion patterns of "C derived from intraperitoneal doses of ring-labeled and methoxy-labeled aflatoxin Bi were investi gated in male rats. It was found that 70-80% of the administered radioactivity from both compounds was excreted during the 24 hours following administration. A major excretory route of the ring-labeled material was through biliary excretion into feces, which accounted for nearly 60% of the administered 14C. A
