Abstract:: Taking 112 walnut local varieties kernel from different eco-geographical regions as research materials，protein content，crude fat content and main fatty acid content and composition were determined by the method of Kieldahl，Soxhlet extraction and gas chromatography respectively，substance diversity and content variation of walnut in different region were analyzed.The results showed that the average content of protein were 15.97%，crude fat were 64.26%，the average content of main fatty acid were linoleic 55.49%，oleic 24.70%，linolenic 11.66%，palmitic 6.05%，stearic 1.98% respectively.The unsaturated fatty acid content reached to 91.85%，the correlation analysis showed significant differences (P<0.05)in the fatty acid content.
