摘要
采用混合溶剂萃取法从新鲜尾巨桉木材中提取低分子量成分,并用气相色谱/质谱法联机分析技术,用色谱峰面积归一化法计算各组分的相对含量。共分离出42个峰,并从中鉴定出30个化合物,占总峰面积的87.88%。主要成分为1,2-邻苯二甲酸二异辛酯(17.53%)、1,2-邻苯二甲酸双(2-甲丙基)酯(cas)(8.48%)、二丁基酞酸盐(8.12%)、丁二酸-甲基-双(1-甲丙基)酯(7.02%)、乙二酸双(2-甲丙基)酯(cas)(6.89%)、2,6,10,15,19,23-六甲基-鲨烯(4.53%)、十六酸乙酯(cas)(3.77%)、2-异丙基-1-甲烷基萘(2.97%)、二十六烷(2.63%)、己二酸双(2-乙己基)酯(1.98%)、二十八烷(1.93%)、鹿尾草碱(1.90%)等。
The chemical components of benzene/ethanol extractives of fresh Eucalyptus urograndis wood chips were separated and identified by GC/ MS after enriching. Relative content of each chemical component was determined by area normalization. Thirty compounds representing 87.88% of the extractives which take on 42 peaks were identified. The most abundant and valuable constituents were 1, 2-benzenedicarboxylic acid, diisooctyl ester (17.53%), 1, 2- benzenedicarboxylic acid, bis (2- methylpropyl) ester (8.48%) , dibutyl phthalate (8.12%) , butanedioic acid, methyl-, his (1-methylpropyl) ester (7.02%) , hexanedioic acid, his (2-methylpropyl) ester (6.89%), 2, 6, 10, 15, 19, 23-hexamethyl-2, 6, 10, 14, 18, 22-tetracosahexaene (4.53%), hexadecanoic acid, ethyl ester (3.77%) , 2-isopropyl-1-methylnaphthalene (2.97%) , hexacosane (2.63%) , di (2-ethylhexyl) adipate ( 1.98% ) , octacosane ( 1.93% ) , salsoline ( 1.90% ) and so on.
