摘　　要：目的研究麻疯树叶中的低极性化学成分。方法采用溶剂提取法、硅胶柱层析法分离得到石油醚提取物Ⅰ和Ⅱ,并用气相色谱-质谱联用对其化学成分进行分离、鉴定及分析。结果从石油醚提取物Ⅰ中分离鉴定出11种成分,占总提取物的98.00%,其主要成分为9,121,5-十八碳三烯酸乙酯(41.49%)9、1,2-十八碳二烯酸乙酯(16.22%)、十六烷酸乙酯(14.05%);从石油醚提取物Ⅱ中鉴定出13种成分,占总提取物92.40%,其主要成分为邻苯二甲酸二辛酯(21.63%)、5-己基-2-环戊酮(10.66%)、正二十烷醇(10.23%)。提取物Ⅰ和Ⅱ所鉴定成分中除十六烷酸乙酯外,其它成分均不同。结论该研究为麻疯树叶的综合开发利用提供了科学依据。Objective To study the chemical constituents of the leaves of Jatropha curcas L.in Hainan. Methods The petroleum ether extract Ⅰand Ⅱ were made from the leaves of Jatropha curcas by solvent extractiom method and silica column chromatography,and were isolated and identified by GC-MS method. Results 11 compounds were separated and identified which accounted for 98.00% of total extracts from the extract Ⅰ.The main chemical constituents were 9,12,15-Octadecatrienoic acid,ethyl ester（41.49%）,9,12-Octadecadienoic acid,ethyl ester（16.22%）,Hexadecanoic acid,ethyl ester（14.05%）.13 compounds were separated and identified which accounted for 92.40% of total extracts from the extract Ⅱ.The main chemical constituents were Dioctyl phthalate（21.63%）,5-Hexyl cyclopentanone（10.66%）,1-Eicosanol（10.23%）.The chemical constituents were different between the extract Ⅰand Ⅱ except Hexadecanoic acid,ethyl ester. Conclusion This study provides scientific foundations for exploitment and utilization of the leaves of Jatropha curcas.
