The presence of aesculin and a scopoletin glycoside has been demonstrated in extracts of potato tubers, and quercetin, caffeic acid, aesculetin and scopoletin in hydrolysed extracts. A spectrophotometric method for the estimation of phenolase activity is described and using this and conventional manometric techniques the activity of a potato phenolase preparation has been measured with a large number of phenolic compounds.
