摘要： 清香木为优良的抗旱及观赏植物,并有宜人的香气。本研究采用热脱附-气相色谱/质谱(TCT-GC/MS)联用技术,对动态顶空密闭循环吸附捕集的盆栽及露地生清香木活体枝叶挥发物进行分析检测。结果表明,清香木香气成分主要为萜烯类化合物,但盆栽和露地生清香木香气中萜烯类化合物的具体检出种类存在差异;露地清香木香气中的β-蒎烯(30.62%)、莰烯(14.39%)和α-水芹烯(21.62%)含量明显高于盆栽清香木(β-蒎烯13.28%,莰烯1.34%,α-水芹烯3.60%);盆栽、露地清香木香气中的α-蒎烯(分别为8.96%和8.55%)、对花烃(1.19%和1.71%)、柠檬烯(4.24%和5.48%)含量较接近,而盆栽香气中的2-崖柏烯(9.36%)含量明显高于露地(4.16%)。

Abstract: Fragrances of Pistacia weinmannifolia,an anti -drought and fine gardening tree,changed as they were invarious cultivation environments,such as potted indoor and planted in open field outdoor,thus they were closely and circularlyhead -space sampled within adsorptive tubes,then analyzed by thermal -desorption cryo -trapping gas chromatography/mass spectrometry(TCT -GC/MS).Results showed that terpenes were both high contained in the two samples.β -pinene(30.62 %), camphene(14.39 %)and α-phellandrene(21.62 %)in the outdoor sample were considerablyhigher than those in the indoor one(β -pinene 13.28 %, camphene 1.34 % and α-phellandrene 3.60 %).It wasnear to each other of both the two samples on contents of α-pinene,p -cymene and limonene,but 2 -thujene in the indoorsample(9.36 %)was rather higher than that in the outdoor one(4.16 %).
