Summary

16 Species of Loranthaceae were investigated for the presence of toxic proteins. With regard to this character three groups of species may be discerned:

a) No toxic proteins are present. Their toxicity must be caused by other types of constituents (10 species).
b) Viscotoxin–like toxic principles seem to be present besides other toxins of still unknown structure (5 species).
c) Phoradendron serotinum contains the same type of basic, toxic proteins («viscotoxin») as Viscum album. The toxicity of representatives of group c seems to be caused by viscotoxins exclusively.
