摘要:
采用水蒸气蒸溜法提取其根、茎、叶中的挥发油,利用GCMS联用仪对其化学成分进行分析,以归一化法计算各个化学成分的相对含量。鸭儿芹根挥发油中共分离出11个峰,鉴定出11种化合物,占总离子峰的98.61%,主要成分为α芹子烯、γ芹子烯等;茎中共分离出25个峰,鉴定出25种化合物,占总离子峰的100.00%,主要成分为α芹子烯、β芹子烯、β月桂烯、β蒎烯、松油烯等;叶中共分离出18个峰,鉴定出18种化合物,占总离子峰的100.00%,主要成分为β芹子烯、α芹子烯、β石竹烯(15.09%)等。鸭儿芹根和叶挥发油中主要成分为倍半萜类,单萜类含量很低或没有,而茎中单萜类成分占很大优势,约为50.00%。鸭儿芹根、茎、叶挥发油的成分及含量有较大差异。该研究为鸭儿芹的综合开发利用提供了一定科学依据。
Abstract:
The chemical constituents of the essential oil which were extracted from roots,stems and leaves of Cryptotaenia japoniawere by steam distillation were analyzed by GCMS. The relative contents of these constituents were calculated using square peaks to normalization. 11 peaks were separated from root,and 11 constituents were identified,accounting for about 9861% of the total essential oil. The main constituents were αselinene and γselinene;in the stem, 25 peaks were separated and 25 constituents were identified,composed about 100% of the total essential oil. The main constituents were αselinene,βselinene,βmyrcene,βpinene,terpinene,etc;in the leaf,18 peaks were separated and 18 constituents were identified,composed about 100% of the total essential oil. The main constituents were βselinene,αselinene,βcaryophyllene(15.09%),etc. There were mainly sesquiterpenes in the essential oil from root and leaf,but monoterpenes were seldom found. While there were mainly monoterpenes in the stem,composed about 50% of the total essential oil. The constituents and contents of essential oil of root,stem and leaf had some differences, and this study would provide some scientific basis for comprehensive exploitation.
