## Abstract Polyphenol oxidase (PPO) obtained from wheat bran catalyzed the oxidation of 4βmethyl catechol. Phenolic compounds found naturally in crude extract played role as an endogeneous substrate and activity of crude extract needed correction. Activity versus enzyme concentration gave a linear

## Abstract Polyphenol oxidase extracted from oil bean (__Pentaclethra macrophylla__) seeds was purified 165βfold over the crude enzyme extract. The apparent molecular weight of the enzyme by gel filtration was 110.8 k Β± 9.0 k while SDSβPAGE indicated a single species of molecular weight 28.0 k. A
