虎榛子叶片挥发性成分HS-SPME&GC-MS分析

Analysis of Volatile Components from Ostryopsis davidiana Leaves Using HS-SPME & GC-MS

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。

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 .
