Comparative Research on the Essential Oil from Senecio scandens
Comparative Research on the Essential Oil from Senecio scandens

摘要:

[Objective]The aim was to study the chemical components and relative content of the essential oil from the cultivated and the wild Senecio scandens,expecting to provide the scientific evidence for the reasonable utilization of Senecio scandens.[Method]The essential oil was extracted from the cultivated and the wild Senecio scandens with the steam distillation,and was analyzed with GC-MS.[Result]The results showed that main chemical components of the cultivated-essential oil and the wild-essential oil had certain difference:the 23 compounds and 21 compounds were identified from the cultivated and the wild Senecio scandens respectively,the 13 compounds were the same among them.The cultivated-essential oil contains 17 terpenoids,6 aliphatic and aromatic compounds,while the wild-essential oil contains 9 terpenoids,12 aliphatic and aromatic compounds.The relative content was different:the main components of essential oil from the cultivated Senecio scandens were 11.60% of α-farnesene,13.49% of α-caryophyllene,8.57% of caryophyllene oxide,10.86% of palmitic acid and 9.00% of linoleic acid,while that of essential oil from the wild Senecio scandens were 8.10% of α-farnesene,19.50% of α-caryophyllene,14.22% of caryophyllene oxide,21.45% of palmitic acid and 13.66% of linoleic acid.[Conclusion]The chemical components of essential oil in Senecio scandens was identified and each content was determined by this method,thus the study will provide the scientific evidence for the reasonable exploitation and sustainable utilization of Senecio scandens.
