A method for analysis of γ-aminobutyric acid(GABA) in germinated brown rice by high performance liquid chromatography(HPLC) was developed. A gradient elution was used for the separation and quantification of GABA pre-column derivatization with AQC. The column was Waters AccQ·Tag for free amino acids. GABA was determined with UV detector at 248.0nm. Good linearities were observed within the ranges from 0.10 to 1.0 with equation of Y=3.0×106X-7877.6 (r=0.9999). And the recoveries were 99.0%~100.5% for GABA. T...
