GC-MS分析流苏虾脊兰叶中挥发性化学成分

An Analysis on the Volatile Chemical Composition in the Leaves of Calanthe Alpina by GC-MS

目的研究流苏虾脊兰叶中挥发性化学成分。方法采用水蒸气蒸馏法提取流苏虾脊兰叶中挥发油。利用GC-MS测试其化学成分。结幂通过检索从挥发油中鉴定出19种物质,占总成分的94.40%,主要成分为:4-乙烯基-2-甲氧基苯酚(60.33%)、正十六酸(13.10%)、十八-9-炔酸(14.56%)。结论流苏虾脊兰叶中主要挥发性化学成分为4-乙烯基-2-甲氧基苯酚、正十六酸、十八-9-炔酸。

Objective： To study the .ridge volatile chemical components containing in the leaves of calanthe alpina. Methods： The volatile oils in the leaves of calanthe alpina were extracted by steam distillation and its chemical composi- tions were tested by GC-MS. Results： There were 19 kinds of substances extracted from the volatile oil, accounting for 94.40 % in the total components, and their main ingredients were 4-vinyl-2-methoxy phenol （60.33 % ）, n-hexade- canoic （13.10 % ）, and 18-9-acetylene acid （14.56 % ）. Conclusion： The main volatile chemical components in the leaves of calanthe alpina are 4-vinyl-2-methoxy phenol, n-hexadecanoic and 18-9-acetylene acid.
