Abstract

 

Perillyl alcohol and d-limonene are naturally occurring plant compounds that exhibited anti-carcinogenic activities in mammary tumor models.  The effects of these monoterpenes at the initiation stage of aflatoxin B1-induced hepatocarcinogenesis were investigated.  Male F344 rats were fed Control or treatment diets throughout the study and exposed to aflatoxin for 5 days.  Three days after the last aflatoxin dose, blood and liver samples were obtained.  Analysis of liver samples showed that both limonene and perillyl alcohol significantly inhibited (p<0.05) aflatoxin-DNA adducts formation in hepatocytes.  The monoterpenes may have potential for use as chemopreventive agent against aflatoxin-induced liver cancer.
