Water-saturated butanol precipitated a protein fraction from the petroleum ether-soluble oil of barley flour. The protein fraction (0.84% of the total free oil) contained 45.0% protein and 24% carbohydrate. The protein migrated as a doublet during starch-gel electrophoresis. The lipoprotein contained relatively high amounts of the amino acids lysine, arginine, and cysteine. The protein isolated from barley flour oil appeared to have properties that were similar to those of the protein fractions isolated from wheat flour oil.
