摘要
采用微波-乙醇工艺提取苏铁蕨的木质根上茎直立部分,经GC-MS分析,分离出60个峰,并确认了其中55个成分,所鉴定的组分占总峰面积的97.88%。苏铁蕨中的脂溶性成分被划分为4类化合物:有机酸类、倍半萜类、烷烃类和环硅氧烷类。经结构分析,各类化合物内部的分子结构间存在高度的相关性,特别在烷烃类与环硅氧烷类中,相邻的化合物间具有相同的结构差。其中环硅氧烷的结构在蕨类植物研究中尚未见报道。
The upstanding part of xylem caudex of Brainia insignis （ Hook. ） J. Sm. was extracted by organic solvents under low temperature and mild microwave irradiation. The extract was analyzed by GC-MS, 60 peaks were separated and 55 compounds were identified, which accounted for 97.88 % of total peak area. The volatile components in B. insignis were classified into four structure groups： organic acids, sesquiterpenes, alkanes and cyclosiloxanes. From structural analysis, there are close correlations among individual groups of compounds. Especially in alkane and cyclosiloxane groups, there are similar structural differences between the neighboring compounds. The cyclosiloxanes have not been reported hitherto in fern research.
