为进一步明确大叶桉的化学成分,对大叶桉叶水浸提液分别用不同极性的有机溶剂石油醚、乙酸乙酯和正丁醇进行萃取,对各萃取相进行 GC-MS 分析.结果表明：大叶桉叶水浸提液共含有37种化合物,其中,石油醚萃取相中含有20种,主成分为草酸丁基异己酯(37．24％)；乙酸乙酯萃取相中含有16种,主成分为2,2-二亚甲基双[6-(1,1-二甲基乙基-4-甲基)]-苯酚(50．05％)；正丁醇萃取相中含有5种,主成分为丙基-2-甲基丁酸酯(54．57％).在所有成分中,酯类物质居多,也有少量的烯、酮、醇、苯和烷烃.1-甲基,4-(1-甲基乙基)-1,4环己二烯、2,2-二亚甲基[6-(1,1-二甲基乙基)-4-甲基]苯酚、1-十八烯和二十烷为石油醚和乙酸乙酯的共有成分；1、2-苯二甲酸单(2-乙基己基)酯为乙酸乙酯和正丁醇的共有成分.该研究进一步明确了大叶桉的化学成分,为其在医药、化工和化感方面的应用研究奠定了基础.

With different polarity organic solvent extracted water leaching solution of Eucalyptus robusta leaf and ana-lyzed by gas chromatography-mass spectrometry (GC-MS)in order to make a clear definition of the chemical compo-nents.37 compounds were identified.Among them,the petroleum ether extraction phase contained 20 kinds and main component was oxalic acid,butyl isohexyl ester (37.24%);Ethyl acetate extraction phase contained 16 kinds and main component was phenol,2,2′-methylenebis[6-(1,1-dimethylethyl)]-4-methyl- (50.05%);N-butanol extraction phase contains 5 kinds and main component was butanoic acid,2-methylpropyl ester (54.57%).Of all the ingredi-ents,ester material in the majority ,also had a small amount of olefin,ketones,alcohols,benzene and alkane.1,4-Cy-clohexadiene,1-methyl-4-(1-methylethyl)-,phenol,2′-methylenebis[6-(1,1-dimethylethyl)-4-methyl-,1-octadecene and eicosane for petroleum ether and ethyl acetate common composition,1,2-benzenedicarboxylic acid,mono(2-ethyl-hexyl)ester for ethyl acetate and n-butanol common composition.The study further defined the chemical components of E .robusta and builted the foundation for its application in pharmaceutical,chemical and allelopathy.
