滨海前胡不同部位挥发油化学成分GC-MS分析

Analysis of Volatile Oils from Different Parts of Peucedanum japonicum by GC-MS

采用水蒸气蒸馏法分别提取滨海前胡Peucedanum japonicum根、茎叶、花及果实中挥发油,使用GC-MS分析挥发油并鉴定其化学成分,比较不同部位挥发油的化学成分及含量差异。结果显示,从根、茎叶、花和果实挥发油中分别鉴定出58、36、40和45种化学成分,分别占各部位挥发油总量的95.60%、98.03%、95.82%和95.36%。四个部位共鉴定出79个化学成分,其中有相同化合物20种,主要成分为α-侧柏烯、α-蒎烯、β-月桂烯、β-蒎烯等。

To evaluate the differences among chemical components and contents of volatile oils from roots, stem leaves, flowers and fruits of Peucedanum japonicum, the volatile oil was extracted by steam distillation from different parts of P. japonicum and chemical constituents of the volatile oil were identified by GC-MS. The results showed that 58, 36, 40 and 45 constituents were identified respectively in roots, stem leaves, flowers and fruits, accounting for 95.60%, 98.03%, 95.82% and 95.36% of the total volatile oils respectively. Seventy-nine constituents were identified in all four parts of P. japonicum, of which twenty constituents were present in all four parts. The main ingredients were α-thujene, α-pinene, β-myrcene, β-pinene, etc.
