| 摘 要： | 摘要:沙棘挥发物释放量极少，在采集和测定过程中，本底干扰是影响其精确定量的关键因子。针对采样装置中连接管路气味物质对沙棘挥发物的严重干扰，本研究对五种不同产地、不同材质的连接管进行挥发物采集，并通过热脱附-气相色谱-质谱联用（TCT-GC-MS）进行测定。结果表明，美国产食品级聚氯乙烯管（PVC）杂质峰最小，比较适宜采集沙棘痕量挥发物。在近自然状态下，壬烷、辛烷、3-甲基丁醇、戊醛、2-甲基丁醛、2-壬烯醇、2-苯甲酸叶醇酯为沙棘枝叶主要挥发物组分。该方法可以降低干扰、提高信噪比，为低释放型植物挥发物的采集分析提供了新的参考依据。 |

| Abstract: | Leaves ofHippophae rhamnoides normally release small quantities of volatile chemicals. In volatiles collection and determination, the interference of background is the key factor influencing accurate quantitative analysis. For the great interference of odor from connecting pipe to volatiles, volatiles from Hippophae rhamnoides were collected using five connecting pipe from different places and material and their components were analyzed using TCT-GC/MS. The results indicated that, the impurity peaks from PV... |
