Abstract
A method was developed specifically for the determination of glutamine and asparagine in the presence or absence of other amino acids. The amino acids were derivatized by o-phthalaldehyde/ 2-mercaptoethanol and separated by isocratic elution with a mobile phase consisting of acetonitrile and sodium acetate buffer. An application of the method for the analysis of glutamine and asparagine in the enzymatic hydrolysate of cottonseed protein is described.
