We employed gel filtration, polyacrylamide gel electrophoresis, amino acid autoanalyzer, thin layer chromatography for determining protein and lipid composition in walnut. The walnut contained 22.18% of crude protein and 64.23% of crude lipid. Glutamic acid (38.60%) was the major amino acid in soluble protein, followed by arginine and aspartic acid. The sodium dodecyl sulfate polyacrylamide gel electrophoresis analysis showed 12 band in soluble protein of walnut, and collection rate of main protein fraction purified by Sephadex G-150 was 60.67%. The molecular weight for the main protein was estimated to be 43,000. The lipid fraction obtained by silicic acid column chromatography were mainly composed of about 93.05% neutral lipid, whereas compound lipid was only 7.0% level
