| Abstract: | The volatile oil from Eucalyptus urophylla×E.grandis leaf was extracted with the method of solid phase micro-extraction and its chemical composition was qualitatively and quantitatively analyzed with the method of gas chromatography-mass spectrometry combined with gas chromatography retention index.There were 86 volatile components identified in the leaf oil,40 of these components each had relative contents over 0.3% and together accounted for over 89.65% of the total weight of the volatile leaf oil.The main components were eucalyptol（33.10%）,alpha.-pinene（10.58%）,benzene,1-methyl-2-（1-methylethyl）（8.98%）,3-cyclohexene-1-methanol,.alpha.,.alpha.,4-trimethyl-,acetate（6.96%）,ethene,methoxy（3.13.%）,3-cyclopentene-1-acetaldehyde,2,2,3-trimethyl（1.59%）,hexanal（1.54%） and hexane（1.42%）. |
