Esculin will not luminesce with peroxidase and H2O2, but pyrogallol or gallic acid will.
The plant extract loses the power to cause such luminescence on boiling and the peroxidase will not dialyze.
This peroxidase was found in the skins of black agouti, chocolate and blue rabbits, but not in yellow or orange rabbits.
