摘　　要：[目的]分析苦楝枝条及叶片挥发物成分,找出可能对星天牛产生引诱效果的化学物质。[方法]通过顶空-固相萃取苦楝树枝条及叶片,采用色谱、质谱仪对成分进行检测分析。用SPSS27软件对试验数据进行独立样本t检验。[结果]苦楝枝条与叶片的挥发性成分存在显著差异,枝条共检出挥发性成分47种,叶片29种,共同成分17种。其中枝条主要挥发性成分为乙醇、二丙基二硫、α-依兰油烯、d-柠檬烯、双环大根香叶烯、桧烯、丙硫醇、β-月桂烯等,叶片主要化学成分为(3E)-4,8-二甲基壬-1,3,7-三烯、乙醇、桧烯、双环大根香叶烯、β-月桂烯、d-柠檬烯等。枝条和叶片中单萜类化合物(C_(10)H_(16))与倍半萜类化合物(C15H24)含量较多,其中枝条中单萜类化合物含量占21.38%,倍半萜类化合物占27.73%;叶片中单萜类化合物占40.07%,倍半萜类化合物占17.35%。枝条与叶片中含量较多且成分相同的是乙醇、d-柠檬烯、双环大根香叶烯、桧烯、β-月桂烯。[Objective]Analyze the volatile components of Melia azedarach branches and leaves to identify the chemical substances that may have an attractive effect on Anoplophora chinensis.[Method]The branches and leaves of the Chinese toon tree were extracted by headspace solid-phase extraction,and the components were detected and analyzed by chromatography and mass spectrometry.The test data were analyzed by independent sample t-test using SPSS 27 software.[Result]There are significant differences in the volatile components between the branches and leaves of Melia azedarach.A total of 47 volatile components were detected in the branches and 29 in the leaves,with 17 common components.The main volatile components of the branches are ethanol,dipropyl disulfide,α-muurolene,d-limonene,bicyclogermacrene,sabinene,propanethiol,β-myrcene,etc.The main chemical components of the leaves are(3E)-4,8-dimethylnon-1,3,7-triene,ethanol,sabinene,bicyclogermacrene,β-myrcene,d-limonene,etc.Monoterpenoids(C_(10)H_(16))and sesquiterpenoids(C15H24)are abundant in both branches and leaves.Among them,the content of monoterpenoids in branches accounts for 21.38%,and sesquiterpenoids account for 27.73%;the content of monoterpenoids in leaves accounts for 40.07%,and sesquiterpenoids account for 17.35%.The components with high contents and the same components in both branches and leaves are ethanol,d-limonene,bicyclogermacrene,sabinene,andβ-myrcene.
