Main characteristic index and fatty acid component of walnut oil extracted from 9 walnut sam- ples planted in Yunnan and 15 walnut oil samples directly collected from market were analyzed and test- ed. The result showed that the refractive index of walnut oil was 1. 475 - 1. 477, relative density 0.916 - 0. 924, iodine value 143.7 -152.2, saponification value 189.0 -200.6. The fatty acid component of walnut oil sample was palmitic acid 3.08% -7.91% ( average 5.79% ), stearic acid 1.48% -2.75% ( average 2. 13% ), oleic acid 17.45% - 25.57% ( average 21. 83% ), linoleic acid 56.97% - 66. i2% ( average 61.58% ), linolenic acid 6.30% - 9.65% ( average 7.7% ) , the content of three un- saturated fatty acids accounts for more than 91% of total tested fatty acid.
