This invention relates to a method for determination of cholinesterase activity, characterized by using, as a substrate, a choline derivative represented by the general formula (I): ##STR1## wherein X is a halogen atom; Y.sub.1 is a hydroxyl group as a substituent in the 2- or 5-position; and Y.sub.2 is a hydroxyl group as a substituent in the 3-position.
