大活茎挥发油成分分析

Chemical Constituents of Essential Oil from Angelica dahurica Stem

采用水蒸气蒸馏的方法从大活茎中提取挥发油,运用GC-MS联用技术分析鉴定了其中的88个组分,主要成分是脂肪酸酯、酸及倍半萜类化合物,含量高于或近于5%。大活茎含有根部挥发油的主要成分,同时也含有一些根部所不含有的化学成分,且含量较高。通过对大活挥发油的分析,为大活茎的进一步开发利用提供了科学依据。

The essential oil extracted from the stem of Angelica dahurica through steam distillation was analysed by GC-MS. A total of 88 components were identified, and the main constituents with content near or above 5% are fatty acid ester, acid and sesquiterpenoids. The stem of Angelica dahurica not only contains the main constituents in the root, but also has some high contents of chemical constituents the root doesn＇ t have. The analytical result of the chemical constituents of essential oil from the stem of Angelica dahurica can provide a scientific foundation for further development and utilization.
