All globulin components hitherto found in many species of seeds, α, β, r and δ globulins, were identified in rice grain by ultracentrifugal experiments and gel-filtration chromatography. Among them, γ globulin was found to occur in high concentration in embryo and bran which were the most active parts in biological functions of rice grain. Then γ globulin was isolated from embryo by gelfiltration chromatography on a Sephadex G-200 column. Purified γ globulin was homogeneous in ultracentrifugal analysis and it was found to be insoluble in cold saline solution. On the other hand, α and β globulins were found to be more concentrated in endosperm with considerable heterogeneity.
