摘　　要：目的:分离和鉴定檵木及其变种红花檵木叶的脂肪酸成分。方法:采用索氏提取法提取脂溶性成分,气相色谱-质谱(GC-MS)联用法对其进行鉴定。结果:从檵木、红花檵木绿叶和红花檵木红叶中各分离鉴定出31、26和30种成分,其中,三种叶片中脂肪酸种类分别为19、14和16种,分别占总峰面积的99.09%、95.31%和98.83%。在三种叶片中含量较高的成分为油酸(30.77%、47.01%、75.28%)、亚油酸(48.49%、29.26%、0%)、棕榈酸(9.83%、8.87%、11.71%)、硬脂酸(3.86%、3.18%、4.88%)、山嵛酸(2.37%、2.17%、2.58%)。结论:檵木和红花檵木叶中含有大量不饱和脂肪酸,可作为中药材原料。Objective ： To extract and analyze fatty acids in leaves of L. chinense Oliver and L. chinense var. rubrum Yieh. Methods： The fatty acids were extracted with Soxhlet extractor and identified by the GC-MS method. Resuhs： 31, 26 and 30 components were identified from the leaves of L. chinense, the green leaves and red leaves of L. chinense vat. rubmm. There were 19, 14 and 16 kinds of fatty acid in the respective leaves, which accounted for 99.09% , 95.31% and 98.83% of the total extraction, respectively. The main components in the extraction were oleic acid （30. 77%, 47. 01%, 75.28% ）, linoleic acid （48.49%, 29. 26%, 0% ）, hexadecanoic acid （9. 83% , 8.87%, 11.71% ）, octadecanoic acid （3.86%, 3, 18%, 4. 88% ） and docosanoic acid （2. 37%, 2. 17%, 2. 58% ）. Conclusion： Many kinds of unsaturated fatty acids exist in leaves of L. chinese Oliver and L. chinense var. rubrum Yieh. The leaves of these two plants can he used as the traditional Chinese medicine.
