- 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(-)-β-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 110 volatile 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.
