Abstract: An efficient and sensitive analysis of γ-aminobutyric acid (GABA) was described. The results showed that the minimum detection limit was 0.0176g/L. The standard curve for GABA showed good linearity over the concentration range of 0.3~10g/L. It indicated that the average recovery is 99.04% with a relative standard deviation of 2.376%. The method is sensitive, convenient and accurate, meeting the practical requirement.
