摘要
用GPC、GC-MS-DS法对中国漆树液中漆酚与虫漆酚精油化学成分进行了研究。其主要成分为3-C_(15)和C_(17)烃基取代的邻苯二酚化合物,其中三烯漆酚和单烯虫漆酚含量最高。其它成分为4-C_(15),C_(17)烃基取代的邻苯二酚及3-C_(15)和C_(17)烃基取代的单酚化合物。气相色谱分离鉴定组分占精油含量的98％以上。原始漆树液中内含7％～9％漆酚聚合物。
The chemical compositions of the essential oil of laccol and urushiol from the sap of Chinese lacquer tree are studied by GPC and GC-MS-DS techniques. The main components of these oils are 3-C15 and 3-C17 alkylcatechols, respectively, which were identified by their standard samples. The most abundant constituents are the monoenyl laccol and the trienyl urushiol. The other components are 4-C15 alkylcatechols and 3-C15 and C17 alkylphenol. More than 98% of the commponents in essential oil were separated and identified by GC. The sap of lacquer tree contains 7%-9% of polymeric urushiol.
