| Rice contains several kinds of bio-functional components. In this study, γ-aminobutyric acid (GABA) and tocopherol, or Vitamin E were identified and their relationships to antioxidant activity using DPPH assay of both brown and pre germinated Thai rice were studied. GABA, one of the two inhibitory neurotransmitters that make the neuron resistant to stimulation by excitatory neurotransmitters and inhibitor of some cancer cells activity. Tocopherols, or Vitamin E, are natural antioxidants which help improve blood cholesterol. Identification of GABA and tocopherol in both brown and pre-germinated brown rice grown from different locations were conducted in eleven varieties, namely: Khao Dawk Mali 105, PTT1, CNT1, RD31, Sang Yod, RD6, Hom Kradang-nga, Niaw Dam... |
