Determination of 2-aminobutane in potatoes using high-performance liquid chromatography

Abstract

Development work on the use of 2-aminobutane to control certain potato-tuber diseases necessitated the development of a convenient and sensitive analytical method for residue determination. The amine was distilled from potatoes, dansylated and determined using reversed-phase high-performance liquid chromatography with fluorescence detection. Recovery of 2-aminobutane by distillation was about 95% from standard solutions and 92% from treated potatoes. The lower limit of detection is below 0.2 µg kg^–1.
