Trypsin inhibitor activity of basidiomycetous mushrooms

The trypsin inhibiting activities (values) of 55 common and edible mushroom samples (of 35 taxa) were measured quantitatively. The inhibiting activiti es ranged between 0.36 and 10.42 TIU/mg dry mass. The largest values were f ound for Laccaria and Hygrophorus species, Craterellus cornucopioides, Gomp hidius glutinosus, Macrolepiota rhacodes and Hydnum repandum. The inhibitin g activities found were higher than those of cereals but lower than those o f some fabaceous plants.
