摘　　要：目的:分析匙羹藤叶石油醚浸泡物的化学成分。方法:用石油醚浸泡匙羹藤叶,并用GC-MS法分离分析其成分及相对含量。结果:从匙羹藤叶的石油醚浸泡物分离出13个化学成分,鉴定了11个化学成分,占总质量的99.35%。结论:匙羹藤叶石油醚浸泡物主要的化学成分是正十六烷酸,2,6,10,15,19,23-六甲基-2,6,10,14,18,22-二十四烷六烯和十八烷,分别占总质量的23.28%,26.34%,21.35%,研究结果为匙羹藤叶化学成分的研究提供了科学依据。Objective： To analyze the chemical compositions and their relative content of the petroleum ether immersion of the leaves of Gymnema sylvestre. Method： The chemical compositions of petroleum ether immersion of leaves of Gymnema sylvestre were separated and identified by GC-MS. Result： Thirteen compositions were found and 11 compositions were identified in the petroleum ether immersion. Conclusion： The principal chemical compositions in petroleum ether immersion were n-hexadecanoic acid, 2, 6, 10, 15, 19, 23- hexamethyl-2, 6, 10, 14, 18, 22-tetracosa hexaene and octadecane, accounting for 23.28% , 26.34% and 21.35% of all quantity respectively. The research could provide scientific basis for chemical composition researches of leaves of Gymnema sylvestre.
