摘　　要：[目的]探明小叶杨叶片气味物质的组成及其诱蛾活性成分。[方法]以2年生小叶杨叶片为材料,采用水蒸气蒸馏法提取萎蔫叶片中的挥发性物质,并用气相色谱-质谱联用仪(GC-MS)对提取物的组成进行检测。[结果]水蒸气馏出物中共含有甲苯、环庚酮、环己二酮、1,2-环己二酮和邻羟基苯甲醛等16种化合物,其中环庚酮含量最高(相对含量为33.93%),其次为环己二酮(相对含量为31.55%)。[结论]小叶杨萎蔫叶片水蒸气溜出物中大部分物质为酮类化合物、醇类化合物、杂环类、醛类、酚类等物质。[ Objective ] The study was to prove the composition ＇and the moths trapping active components of odors matter from Leaves of Populus simonii Carr. [ Method ] With leaves of 2 years old P. simonii as the materials, their volatile constituents was extracted by steam distillation method, and the composition of the extract was detected by gas chromatograph-mass spectrometer （GC-MS）. [ Result] There were 16 kinds of compounds such as toluene, cycloheptanone, cyclohexanedione, 1,2-cyclohexanedione and o-hydroxybenzaldehydc in stem distillate, among which the content of cyeloheptanone was the highest （ relative content of 33.93% ）, and the following was that of eyclohexanedione t （relative content of 31.55% ）. [ Conclusion] Stem distillate from withered leaves of P. simonii mainly was ketone compounds, alcohol compounds, heterecyclic, aldehydes and phenols etc.
