Errors of determination in our previously reported chemical method of thioctic acid were induced from the following factors : (1) The time elapsed before reading the ultraviolet absorbancy after mixing dihydrothioctic acid and p-chloromercuribenzoate. (2) The change of pH in the reaction mixture. Changes of thioctic acid level in the blood were compared, after administering thioctic acid to rabbits by various methods.
