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.
