Description

Aflatoxin B1: A potent hepatotoxic and hepatocarcinogenic mycotoxin produced by the Aspergillus flavus group of fungi. It is also mutagenic, teratogenic, and causes immunosuppression in animals. It is found as a contaminant in peanuts, cottonseed meal, corn, and other grains. The mycotoxin requires epoxidation to aflatoxin B1 2,3-oxide for activation. Microsomal monooxygenases biotransform the toxin to the less toxic metabolites aflatoxin M1 and Q1. [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

aflatoxin B1 : An aflatoxin having a tetrahydrocyclopenta[c]furo[3',2':4,5]furo[2,3-h]chromene skeleton with oxygen functionality at positions 1, 4 and 11.

Toxicity

Aflatoxin B1 (AFB1) is widely distributed in nature and is confirmed to be the most toxic of all the aflatoxins. Its predominant metabolism site is the liver. A silymarin-phospholipid complex was found to reduce the toxic effects of aflatoxin b1 in broiler chickens.
