The interaction of the carcinogenic mycotoxin, Aflatoxin B₁, with the electron-donating molecule, benzene, was studied spectrophotometrically.
The formation of charge-transfer complex between Atiatoxin B₁ and benzene in the presence of zinc chloride was observed and the apparent equilibrium constant of this charge-transfer complex was found to be 0.198 (liter mole^(-1)).
It is assumed that, as the result of this study, some charge-transfer complexes could be formed between the weak electron-accepting Aflatoxin B₁ and strong electron-donating molecules, and the spectral changes occurred in the binding of Aflatoxiu B₁ with proteins or DNA is attributed to the existence of charge-transfer type interaction.
