摘要:
 对白蜡木和水曲柳的木材构造特征和提取液化学成分进行辨析,为白蜡木和水曲柳的辨识提供理论依据。木材宏观与微观构造试验结果表明,2种木材均具有白蜡木属木材的基础构造特征,但在材色、薄壁组织、木射线宽度与含树胶方面稍有不同;白蜡木心材呈现浅黄褐色,而水曲柳心材为栗褐色;水曲柳轴向薄壁组织含有树胶;白蜡木多列射线较宽,而水曲柳多列射线较窄且常含树胶。木材的石油醚提取液气相色谱-质谱(GC-MS)分析发现,白蜡木与水曲柳提取液中分别鉴定出5种和7种相对含量较高的化合物,且相对含量最高的成分均是邻苯二甲酸单(2-乙基己基)酯,分别达到58.647%、58.486%;水曲柳特有化合物为:氯代十八烷和Terephthalic acid,2-ethyhexyl octyl ester,相对含量分别为2.548%、10.770%。这2种化合物可作为辨别2种木材的特征化学物质。
Abstract:
 The wood structure characteristics and chemical components of Fraxinus chinensis and F.mandshurica woods were comparatively investigated to provide a theoretical basis for their identification.The results of wood structure characteristics indicated that two Fraxinus woods presented similar structure characteristics.However,two woods were different in wood color,axial parenchyma,wood rays and gum.The heartwood color of F.chinensis was light yellow brown while that for F.mandshurica was chestnut-like brown.The axial parenchyma of F.mandshurica contained gum.The wood rays of F.chinensis was wider than those of F.mandshurica,while the latter had gum.The chromatography-mass spectrometry (GC-MS) results of petroleumether extractives showed that 5 and 7 kinds of chemical components were identified from F.chinensis and F.mandshurica,respectively.Furthermore,the contents of 2-ethylhexyl monophthalate were the highest in both woods (58.647% for F.chinensis,and 58.486% for F.mandshurica).1-Chlorooctadecane (2.548%) and 2-ethylhexyl octyl p-phthalate,ester (10.770%) were only detected in the extractive of F.mandshurica wood,which could be considered as the characteristic component for the identification of the two woods.
