【摘要】 采用冷水浸渍法从新鲜尾巨桉木片中提取有效成分,经浓缩、干燥、苯-甲醇溶解后,再用气相色谱/质谱法(GC/MS)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35个峰,结合文献调研,鉴定出12个化合物,占总峰面积的53.67%。主要成分为2,6,10,15,19,23-六甲基-鲨烯(18.04%)、2,4’,5-三甲基二苯甲烷(7.68%)、二十五(碳)烷(5.93%)、2,6,10,14-四甲基-十五烷(5.10%)、十九(碳)烷(4.95%)、2,6,10,14-四甲基-十六烷(3.97%)、5,6-二氢5,6-二甲基苯-邻二氮(杂)萘(2.80%)、7,3’,4’-三甲氧基-槲皮素(1.53%)、6,10,14-三甲基-2-十五烷(1.02%)等。更多还原

【Abstract】 The chemical components of cold water extractives of E.Urograndis were separated and identified by GC/MS after enriching and dissolving in benzene-methanol.Relative content of each component was determined by area normalization.12 compounds representing 53.67% of the extractives were identified.The most abundant constituents were 2,6,10,15,19,23-hexamethyl-2,6,10,14,18,22,-tetracosahexaene(18.04%),2,4’,5-trimethyldiphenylmethane(7.68%),pentacosane(5.93%),pentadecane,2,6,10,14-tetramethyl-(cas)(5.10%),nonadecane(4.95%),hexadecane,2,6,10,14-tetramethyl-(cas)(3.97%),5,6-dihydro-5,6-dimethylbenzo[c]cinnoline(2.80%),quercetin 7,3’,4’-trimethoxy(1.53%),2-pentadecanone,6,10,14-trimethyl-(1.02%) and so on.更多还原
