樟子松挥发性有机物释放动态及其抑菌作用

Release Variation of Volatile Compounds from Pinus sylvestnis var.mongolica Litv.and Their Effects on Bacteriostasis

利用SUMMA采样罐收集樟子松(Pinus sylvestnis var.mongolica Litv.)挥发物,通过预浓缩仪与气质联用系统对樟子松挥发物进行分析。研究结果表明:春、夏、秋三季樟子松挥发物的主要成分有萜类、烷烃、烯烃类、醇类、呋喃类、醛类、酮类和含氮化合物7大类物质,其中萜类、烃类物质占主体,且随季节变化显著。(+)-2-蒈烯(占挥发物总量36.84%)、(+)-莰烯(占挥发物总量22.28%)是构成春季挥发物的主要成分,夏季则以2-氯-1-丙烯(占挥发物总量34.31%)为主,秋季以(E)-2,7-二甲基-3-辛烯-5-炔(占挥发物总量59.19%)、桧烯(占挥发物总量11.35%)、莰烯(占挥发物总量9.05%)、β-蒎烯(占挥发物总量6.88%)、β-月桂烯(占挥发物总量4.01%)为主。樟子松的挥发物对空气中的细菌具有抑制作用,以夏季抑菌作用最强。

Pre-concentrated system combined with GC-MS was evaluated for determining volatile compounds from Pinus sylvestnis var. mongolica Litv. by SUMMA canister for sampling. In spring, summer and autumn, the main compounds of volatile compounds are terpene, alkenes, alkanes, alcohol, furan, aldehydes, ketone and nitrogenous compounds, and the terpene, alkenes and alkanes are major component. The component and content have dynamic varieties in different seasons. （＋） -2-caren （36.84%） and （＋） -Camphene （22.28%） are major component in spring, 1-Propene, 2-chloro- （ 34.31% ） in summer, and 3-Octen-5-yne,2,7-dimethyl-（E）-（59.19% ）, sabinene （ 11.35% ）, camphene （9.05%） and beta. -Pi- nene （6.88%） in autumn. Volatile compounds from Pinus sylvestnis var. mongolica Litv. have inhibition against bacteria in air especially in summer.
