| 摘 要： | 本文首次采用顶空固相微萃取技术(HS-SPME)提取该植物挥发性成分,然后通过气质联用技术(GC-MS)结合保留指数以及标样对照对化学成分进行了定性,并通过峰面积归一化法计算出各组分的相对百分含量。试验确定了PDMS/DVB固相微萃取对糖蜜草挥发物的萃取效果最好,并从中鉴定出33种化合物占总挥发性成分的90.94%,主要为烷烃和萜烯类化合物。该研究为开发糖蜜草作为水稻螟虫的驱避植物进行害虫安全有效防治提供理论依据,并为驱避性挥发物的田间应用奠定基础。

| Abstract: | In this study,a head-space solid phase microextraction(HS-SPME) method was developed for extracting the volatile compounds from Melinis minutiflora.Then gas chromatography-mass spectrometry (GC-MS) coupled with retention indicator and comparison with standard samples was used to characterize the components of the volatile compounds.Then the relative proportion of each component was calculated by the peak area normalization method.The results showed that Polydimethylsiloxane/divinybenzene(PDMS/DVB) SPME fibe... |
