Study on Collection Method and Component Analysis of Trace Volatiles from Hippophae rhamnoides Abstract: Leaves of Hippophae 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 PVC made in USA were minimized. It is suitable for collection of trace volatiles. Furthermore, the main volatiles rom Hippophae rhamnoides included Nonane, Octane, 3-methyl-1-Butanol, Pentanal, 2-methyl- Butanal, 2-Hexen-1-ol, 2-Hexenyl benzoate in close natural state. The method can reduce interference and raise signal-to-noise ratio. The method will supply a new reference for collecting and analyzing volatiles of low-release plants.
