Determination of gamma-aminobutyric acid in germinated brown rice by hptlc

摘要

Gamma-aminobutyric acid (GABA) is a neurotransmitter in the central nervous system, and regulates blood pressure, heart rate, sensation of pain and anxiety, lipid levels in serum and assist in insulin secretion to prevent diabetes. GABA, a bioactive component is known to accumulate in rice during germination process. In this study, an attempt was made to investigate the effect of germination process on GABA levels in selected local rice cultivars (Swarna and Lalat) of Odisha, India. High-performancethin layer chromatography (HPTLC) was used for determination of GABA concentration in germinated brown rice (GBR), white rice (WR) and brown rice (BR). Results showed that GABA content in GBR is 1.5 and 2 times more than that in BR and WR, respectively.
