| 摘 要： | 利用SUMMA罐收集落叶松挥发物,采用预浓缩与GC/MS联用系统对不同季节的落叶松挥发性有机物成分进行分析。结果表明:不同季节落叶松挥发物的成分包括萜类、烷烃、烯烃及炔烃类、酮类、呋喃类、醇类、醛类、酸类、酯类8大类化合物,共110种,其中以萜烯类化合物为主,且含量随季节变化显著。(1S,3S)-(+)-间-薄荷-4,8-二烯(12.58%)、植紫三烯(9.02%)、(E)-2,7-二甲基-3-辛烯-5-炔(18.13%)、(Z)-2,7-二甲基-3-辛烯-5-炔(17.63%)构成了春季萜类化合物的主要成分,夏季以1,3-戊二烯(23.53%)为主,秋季则以(-)-蒎烯(17.04%)、IR?α?蒎烯(37.09%)为主。

| Abstract: | Pre-concentrated system combined GC-MS was evaluated for determination of volatile organic compounds(VOCs) from Larix gmelinii using SUMMA canister for sampling.The results showed that a total of 110volatile compounds were identified,the main components of VOCs included terpene,alkane,olefin,ketone,furan,alcohol,aldehydes,acids and ester,and the major component was terpene.The component and content had dynamic varieties in different seasons,the major VOCs of Larix gmelinii in spring were m-Mentha-4,8-diene,(1S,3S)(+)(12.58%),Santolina triene(9.02%),3-Octen-5-yne,2,7-dimethyl,(E)(18.13%),3-Octen-5-yne,2,7-dimethyl,(Z)(17.63%).Major component was 1,3-Pentadiene(23.52%) in summer.The main volatile components were()-beta.-Pinene(17.04%),IR-.alpha.-Pinene(37.09%) in autumn. |
