园艺植物挥发性成分的气质联用分析选用顶空进样器进样可实现自动化，并极大地提高定性定量分析的可操作性。选择具有代表性的精油、樟树叶和花椒种子作为样品，探索顶空进样器进样的最佳炉温。结果显示，精油气质检测的峰值出现在50 ℃炉温；樟树叶和花椒峰值出现在70、80 ℃。试验认为以有机溶剂为主的液体样品，顶空进样器炉温选择50 ℃为宜；对园艺植物含水量较大的固体样品，则以70 ℃为宜。
GC-MS analysis of volatile components in horticultural plants can be automated by headspace sampling, which greatly improves the operability of qualitative and quantitative analysis. Essential oils, Cinnamomum bodinieri leaves and Zanthoxylum bungeanum seeds were selected as samples, and the optimum furnace temperatures of headspace sampling were carried out. The results showed that the peak value of essential oil appeared at 50 ℃, the peak value of C. bodinieri leaves and Z. bungeanum seeds appeared at 70 ℃ and 80 ℃, respectively. It was considered that the optimum temperature of headspace sampling for liquid sample with organic solvent was 50 ℃, and solid samples with high water content in horticultural plants was 70 ℃.
