| Abstract: | The results of gas chromatography-mass spectrometry(GC-MS)analysis show that the volatile components of essential oil from fresh Conyza canadensis with hydrodistillation were more than those with steam distillation,and the mass fraction of limonene was the highest(15.36%),carvone(10.15%) followed it.The results of GC-MS analysis show that more fragrance components were in the essential oil from air-dried Conyza canadensis with steam distillation,and the mass fraction of limonene was the highest(57.68%),tran... |
