Bananas decrease acetaminophen potency in in vitro assays. [PDF]
Edible portions of bananas contain high levels of polyphenol oxidase, which catalyzes reactions in the melanin formation pathway. Tyrosine, a physiological substrate of polyphenol oxidase, has an analogous structure to acetaminophen.

Effect of Polyphenol Oxidase on Deodorization
A mixture of purified polyphenol oxidases (PPO), or acetone powders prepared from fruits and vegetables, and polyphenolic compounds (PPs) totally eliminated a methylmercaptan odor. 2-Methyl-thiochlorogenic acid was isolated from the reaction mixture of methylmercaptan and chlorogenic acid with burdock acetone powder.

Activation of Polyphenol Oxidase of Chloroplasts [PDF]
Polyphenol oxidase of leaves is located mainly in chloroplasts isolated by differential or sucrose density gradient centrifugation. This activity is part of the lamellar structure that is not lost on repeated washing of the plastids. The oxidase activity was stable during prolonged storage of the particles at 4 C or -18 C.
