羽叶栾树花气味分析

Analysis of the components of Floral Scent in Koelreuteria bipinnata

该试验应用动态顶空吸附法收集羽叶栾树花气味,结合应用气相色谱-质谱(GC-MS)技术分离鉴定其化学成分,采用离子流峰面积归一化法计算花气味中各挥发物组分的成分。结果共检测出14个组分化合物,主要物质为α-蒎烯(80.69%),β-蒎烯(5.56%),月桂烯(2.81%),对二甲苯(1.74%),(3E)-4,8-二甲基壬-1,3,7-三烯(1.13%)。

In this study, the dynamic headspace adsorption technique were used to collect the floral ccent inKoelreuteriabipinnata, gas chromatography coupled with mass spectrometry（GC-MS）was used for the detectionand identification of volatile chemical components in Koelreuteriabipinnata.the results show that there are 15compounds. Themain compounds are：β-Pinene（80.69%）, βpinene（5.56%）, β-myrcene（2.81%）, 1, 4-Xylene（1.74%）, （E） -4, 8-dimethyl-1, 3, 7-nonatriene （1.13%） .
