Abstracts:The oil contents and fatty acid compositions of 10 introduced Camellia oleifera varieties seed were determined and analyzed. The results showed that harvest time affected oil percentage and the difference between varieties were significant.Oil percentage of changlin-3 was 0.8% higher than in the region of origin,and oil percentages of changlin-4,changlin-18,changlin-23,and changlin-27 had little difference with those of original region.The oil contents of changlin-3,changlin-4,changlin-18,changlin-23,and changlin-27 were 10.10%,4.65%,6.35%,11.63% and 10.51% higher than that of the control.Camellia oleifera seed oil was mainly composed of oleic acid ,linoleic, palmitic acid and stearic acid.The content of oleic acid ranged from 72.40% to 84.70%，and averaged at 79.34%; the content of linoleic acid ranged from 4.30% to 15.50%，and averaged at 9.47%; the content of palmitic acid ranged from 6.60% to 9.00%，and averaged at 7.75%; the content of stearic acid ranged from 1.20% to 2.10%，and averaged at 2.03% .
