HS-SPME-GC/MS法分析紫萁挥发性化学成分

Volatile Constituents from Osmunda japonica Thunb. by HS-SPME-GC/MS

目的:分析比较紫萁地上部分和根茎中的挥发性成分。方法:采用顶空固相微萃取和气质联用技术(HS-SPME-GC/MS)测定。结果:从地上部分中鉴定了31个化合物,根茎中鉴定了27个;其中8个为二者共有成分,其在地上部分和根茎中所占比例分别为13.99%和40.04%。结论:紫萁地上部分和根茎中的挥发性成分具有较大差异。

Objective：The volatile constituents in aerial part and rhizome of Osmunda japonica.were analyzed by head-space solid micro-extraction,coupled with GC-MS.Thirty-one compounds and 27 compounds were identified from the aerial part and the rhizome of O.japonica separately.Eight compounds were mutual,account for 13.99% of total compounds in the aerial part and for 40.04% in the rhizome.It indicated that the volatile constituents in aerial part of O.japonica are quite different from in rhizome.
