土荆芥挥发油的化学成分分析

AIM The purpose is to analyse the chemical constituents of volatile oil of \%Chenopodium ambrosioides\% L. grown in Fujian. METHODS\ The volatile oil was extracted from \%Chenopodium ambrosioides\% L. by steam distillation and was analysed by chromatography, spectral evidences and GC MS. RESULTS\ Two components were column isolated from the volatile oil, and their structures were elucidated by spectral analysis. 14 compounds were separated and identified which accounted for over 94% of total volatile oil. CONCLUSION\ The main components of volatile oil from \%Chenopodium ambrosiodes\% L. are \%p\% cymene(29.73%),α terpinene(9.02%), ascaridole(23 51%), and α terpinolene or δ 4 carene(31.17%).
