摘要
采用动态顶空吸附法和热脱附-气相色谱-质谱联用法(TCT-GC/MS),在紫金山国家森林公园灵谷寺景区,于10月对金桂日释放的挥发性有机物进行测定分析,对含花朵和不含花朵的枝叶释放含量进行比较,分析其日变化,并初步探讨与环境因素的关系。结果表明:金桂花期时共释放出73种挥发性有机物,以醇类、烯类化合物为主,占83.57%,主要是1,6-辛烯-3-醇、2-呋喃甲醇和β-水芹烯。1/3的挥发物(主要是18.58%的醇类化合物和小部分芳烃类化合物)是由金桂的花朵中挥发出来的。醇类化合物日变化先升后降,烯类化合物先降后升。
Using a dynamic headspace adsorption and thermal desorption cold trapping-gas chromatography-mass spectrometry（ TCT-GC / MS）,we investigated VOCs（ volatile organic compounds） released of Osmanthus fragrans var thunbergii in Linggu Temple area on Purple Mountain National Forest Park in October,and discussed the relationship between emissions and environmental factors. The results showed that 73 kinds of VOCs in total were released during the flowering period.Most of them were alcohols,vinyl compounds,accounting for 83. 57%（ mainly 1,6-octene-3-ol,2-furan methanol and β-phellandrene）. One third of volatiles（ mainly 18. 58% of the alcohol compound and a small portion of aromatic compounds） were from the flowers. Diurnal variation featured that alcohol compounds decreased after increase,and the amount of vinyl compounds increased firstly and then dropped. Our purpose is to guide forest planting to make a choice,and provide a reference to the implementation of refined management of scenic forest.
