Abstract:

In ethereal solution, choline is precipitated by silicotungstic acid. The sensitivity of this reaction is 15,000,000. Choline can be determined in the blood serum by reduction of the silicotungstate obtained the amount of choline present is estimated from the intensity of the blue color obtained. Determination by measuring the intensity of the color of choline reineckate is not possible in the case of very small amounts of precipitate. In the method proposed, use is made of a reaction which gives a color that is 600 times as intense as that of choline reineckate.
