Analysis on the Chemical Composition of the Essential Oil in Rhododendron nivale from Tibet

Chen XiaoYang

Abstract

The chemical composition of the essential oil in Rhododendron nivale from Tibet has been obtained through the steam distillation method,and the essential oil was analyzed using the GC/MC technology.In this experiment,45 compounds have been determined which account for 80.04% in the chemical composition of the essential oil.The results showed Rhododendron nivale was quite different as compared with R.nivale subsp.Boreale in their main composition of the essentail oil,such as δ-cadinene(15.47%),α-cadinol(10.23%),cis,trans-farnesol(8.03%),methyl carvacrol(8.08%),α-cadinol isomer(7.77%),etc.
