Improvement of an analytical method on 6-benzylaminopurine (BAP), a plant growth regulator, and a firstgenerationsynthetic cytokinin for agricultural commodities wasundertaken. Analytical method for BAP in the agriculturalcommodities by gas chromatography in cooperation with nitrogenphosphorousdetector (NPD) was adopted. BAP was extractedwith acetone in all samples followed by the ion-associatedpartitioning method. Vapor pressure of BAP was increased by Nmethylationwith iodide methane [BAP→6-Benzylamino-Nmethylpurine(BAMP)]. Finally, N-methylated BAMP was separatedwith ethylacetate. The quantitation was done by GC using NitrogenPhosphorous Detector with DB-608, a moderate polarity columnunder the temperature-rising condition. The standard calibrationcurve presented the linearity of correlation coefficient (r2)>0.9999,analyzed from 0.2 to 4mg/kg. The limit of quantitation in agriculturalcommodities showed 0.05 mg/kg. The average recoveries of intraandinter-day experiments ranged from 70.4 to 103.5% and 70.3to 105.6%, respectively. The repeatability and reproducibility forintra- and inter-day measurements expressed as a relative standarddeviation (RSD) was less than 10.7 and 8.3%, respectively. Therefore, our newly established analytical method for BAPresidue in agricultural commodities was applicable to the nationwidepesticide residues monitoring program with the acceptablelevel of sensitivity, repeatability and reproducibility.
