HS-SPME-GC-MS分析茸毛木蓝地上部分和根挥发性成分

Volatile Constituents from Aerial Parts and Roots of Indigofera stachyodes by Head-space Solid Micro-extraction,Coupled with GC-MS

目的:分析茸毛木蓝地上部分和根的挥发性成分。方法:采用顶空固相微萃取和气质联用技术(HS-SPME-GC-MS),结合保留指数法首次并用峰面积归一化法测定相对百分含量。结果:从茸毛木蓝的地上部分鉴定了35个化合物,根鉴定了21个化合物,分别占总峰面积85.66%和93.74%。两者有12个共有成分。结论:茸毛木蓝地上部分与根挥发性成分具有差别。

Objective：To search the volatile constituents from aerial parts and roots of Indigofera stachyodes.Method：The volatiles were analyzed by head-space solid micro-extraction,coupled with GC-MS and Kovats indices for the first time.A quantitative analysis in percent was performed by peak area normalization measurements.Result：As a result,35 compounds were identified from the aerial parts,and 21 from roots,85.66% and 93.74% of the total essential constituents respectively.12 compounds were shared in both samples.Conclusion：It was different between the aerial part and roots of I.staclyodes.
