    Abstract：ObjectiveTo determine the fatty acids in seed of Zizyphus jujuba Mill. MethodsThe seed of Zizyphus jujuba Mill. was extracted by Soxhlet extraction. The fatty acids in the oil were esterified by sodium hydroxide-methanol, and then analyzed by gas chromatography-mass spectrometry (GC/MS). Results17 fatty acids were identified in the seed of Zizyphus jujuba Mill, the contents of the identified fatty acids made up to 95.33%, the unsaturated fatty acids were 80.20% and saturated fatty acids were 15.13%. ConclusionThe main components are unsaturated fatty acids in seed of Zizyphus jujuba Mill. ......
