Exploring Phylogenetic Relationships between Hundreds of Plant Fatty Acids Synthesized by Thousands of Plants.

Soxhlet extraction was used to extract oil from the seeds of Xanthium sibiricum Patrin wildly grown in Xinjiang.The effects of extraction time,solid/liquid ratio and extraction temperature on oil yield were studied by single factor and orthogonal array design methods.Besides,the fatty acid composition of the extracted oil was measured by GC-MS.The results showed that the optimal values of the above parameters affecting oil yield were determined to be: extraction time 2.5 h,solid/liquid ratio 1:10 and extraction temperature 75 ℃.Under such conditions,the oil yield was 22.14%.Xanthium sibiricum Patrin seed oil contained mainly unsaturated fatty acids,and the relative contents of linoleic acid,oleic acid,palmitic acid,stearic acid were 85.73%,7.67%,3.76% and 1.35%,respectively.
