摘要：Walnut samples from different sites with different site conditions and management levels were selected to study the effects of environmental conditions or management level on the fatty acid content of walnut oil.The results prove that samples from different sites containe oils from 566.44-761.58 mg/g,which indicate that site conditions can affect total soil contents in walnut.At the same time these results also prove that walnut oil contains very high unsaturated fatty acids which can reach more than 90% and the contents of fatty acids and unsaturated fatty acids in samples from different sources vary greatly,that is,the site environment influences the content of fatty acid.Table 2 proved that 22 fatty acids are all affected by site conditions of samples.
