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。
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 L67% of the extracfives were identified L 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.
