A b s t r a c t - In this work, partial purification of catalase from red cabbage and some properties For the purification, enzyme was extracted from red cabbage with phosphate buffer and centrifuged and activity for crud enzyme was 287.26 unit/ml Then (NH4)2SO4 precipitation was performed to the extracted enzyme and activity was353.26unit/ml
and was dialyzed and activity was of enzyme after dialyses 552.2unit/ml then were studied The pH optimum function of the effectiveness of the enzyme 7 and 30 C optimum temperature and pH was the optimum function of the stability of the enzyme 7 and optimum temperature for the stability of the enzyme was 30 C.
