The difference of γ-aminobutyric acid(GABA) and total flavones as well as alkaloids content(mg·100g-1) in grain and it's malt during 1~9 days germination of 28 barley cultivars were determined by spectrophotometry.The analytical results were as follows:(1) GABA and alkaloids content of barley grains before the germination are higher than that of 1~2 days but clear lower than that of 3~9 days after the germination,the most value for GABA's cumulation between barley grain and it's malt during 1~9 days germina...
