Abstract: Ostryopsis davidiana is an important host plant of Trabala vishnou gigantina. In order to reveal the volatile component in O. davidiana, its leaves were analyzed by HS-SPME & GC-MS and the relative content of each component was determinated by area normalization. The results showed that 39 chemical composition were detected and identified including 5 leaves smell matter(75.61%), 6 aromatic compounds(1.30%), 9 terpene compounds(5.04%) and 19 aliphatic compounds(17.76%). The result may provide basis for developing plant-derived attractants of Trabala vishnou gigantina

摘要： 为探明虎榛子Ostryopsis davidiana叶片挥发物的组成及其相对含量，以长势优植株为研究对象，利用固相微萃取-气相色谱质谱法(HS-SPME & GC-MS)分析其叶片挥发性物质，通过面积归一法计算各成分的相对含量。结果表明，从虎榛子叶片中共鉴定出39种化学成分，其中5种绿叶气味物质，占75.61%；6种芳香化合物，占1.30%；9种萜烯类化合物，占5.04%；19种脂肪族化合物，占17.76%。该结果可为其寄生昆虫栎黄枯叶蛾的植物源引诱剂开发奠定基础。
