Altogether, heterogeneous results of the considered species of
genus Euphorbia L. was determined. For all tested species, N- acetylb-
glucosamidase activity was estimated in different quantities. The
majority exhibited a high exochitinase activity, verified by the
substrate 4-Methylumbelliferyl N- acetyl-b- D-glucosamidinide,
and a specific exochitinase activity higher than 30 U mL mg1 was
determined for 67 species.
