## 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
Polyphenol oxidase (PPO) activity of Γltered extract of ground mango kernel suspension (400 g litre~1) was studied spectrophotometrically at 420 nm using catechol as substrate. The enzyme was most active at pH 6Γ0 and 25Β‘C. Activity was reduced by 50% at pH values of 5Γ0 and 7Γ1, and also at tempera
