Modifications of the comprehensive method for total glycoalkaloid determination

  • T. J. Fitzpatrick

  • P. Gregory


Continuing investigations and queries from workers in the field of potato research have led to minor modifications of the method for the determination of total potato glycoalkaloids (TGA) by Fitzpatrick and Osman (1). These small changes shorten the time for analysis and can possibly give improved recovery of TGA.
