A method of simply and precisely determining the activity of cholinesterase comprises the steps of: mixing a diagnostic solution containing hydroxybenzoate hydroxylase, nicotinamide adenine dinucleotide phosphate reduced form (NADPH) and hydroxybenzoyl choline having the following formula:
with a liquid containing cholinesterase; and measuring the decrease in absorbance of light by NADPH, which corresponds to the consumption of NADPH and in turn the extent of production of hydroxybenzoic acid which is dependent on the activity of the cholinesterase-containing liquid.

The total fractions of cholineesters have been isolated from different parts of Sinapis alba . 4-Hydroxybenzoylcholine has been identified and found to be one of the quantitatively dominating cholineesters in seed extracts of S. alba . The identity of the newnatural product has been confirmed by comparison with synthetic reference compounds. Several different cholineesters are present in this plant
