To identify odorous substances of solid wood, the emission from two types of wood species, namely Phoebe neurantha (Hemsl.) Gamble and Osmanthus fragrans (Thunb.) Lour. was sampled by micro-chamber extractor, combined with the Tenax TA tube and multi-bed tube (carbopack C, carbopack B and carboxen 1000). The odor-active compounds were identified by gas chromatography-mass spectrometry/olfactometry (GC–MS/O), which combine instrumental and sensory analyses. The results showed that, for Phoebe neurantha and Osmanthus fragrans, 12 and 20 kinds of odor-active compounds were identified. The main odor contributors of Phoebe neurantha were “D-limonene, 2-hexanol, 1-heptanol and 2-hexanone”, with the dominant odor impressions of fragrant, irritant, special and fruity. The main odor contributors of Osmanthus fragrans were “camphene, heptanal and pentanal”, while the key odor impressions were spicy, fruity and fatty. VOC concentration and odorous concentration of Phoebe neurantha were higher than Osmanthus fragrans. The proportion of the odorant concentration to the TVOC concentration of Phoebe neurantha and Osmanthus fragrans was 77.39 and 58.68 percent, respectively. The multi-bed tube, which showed excellent adsorption performance for alcohols and compounds with low molecular weight in this study, is able to capture some of the key odor-active compounds that Tenax TA tube cannot collect. Identification of the composition of these two wood species will expand the solid wood odorous substance database and help to establish a method to investigate the odorants with low molecular weight from wood. Through this study, a better understanding of the characteristic odor from wooden materials used in daily life could be obtained.

为了识别实木的有毒物质，需要从两种类型的木材中排放，即楠木（Phoebe neurantha（Hemsl。））和桂花（Osmanthus fragrans（Thunb。）Lour）。通过微型腔室萃取器，与Tenax TA管和多床管（carbopack C，carbopack B和carboxen 1000）结合，对样品进行取样。通过气相色谱-质谱/嗅觉法（GC-MS / O）鉴定了气味活性化合物，该方法结合了仪器分析和感官分析。结果表明，对于楠木和桂花，共鉴定出12种和20种气味活性化合物。楠木（Phoebe neurantha）的主要气味成分分别是“ D-柠檬烯，2-己醇，1-庚醇和2-己酮”，其主要气味印象为芳香，刺激性，特殊和果味。桂花的主要气味成分是“香樟，庚醛和戊醛”，而主要的气味印象是辛辣，果味和脂肪。楠（Phoebe neurantha）的VOC浓度和臭味浓度均高于桂花。楠木和桂花的气味浓度与TVOC浓度的比例分别是77.39和58.68％。多床管在这项研究中显示出对醇类和低分子量化合物的优异吸附性能，能够捕获Tenax TA管无法收集的一些关键的气味活性化合物。鉴定这两种木材的成分将扩展实木有味物质数据库，并有助于建立一种方法来研究木材中低分子量的气味物质。通过这项研究，可以更好地了解日常生活中使用的木质材料的特征气味。
