Chemical composition of essential oil of Artemisia nanschanica Krasch. from Tibetan plateau

The chemical composition of the essential oil of Artemisia nanschanica (Krasch) from the centre of Tibetan plateau was reported for first time. Thirty-four compounds (92.26% of total composition) were identified. The major constituents of the oil were terpenoids (70.86%), thujone (21.3%), heptadiene (16.52%), and linalool (10.94%). The content of 1,8-cineole (9.43%), and camphor (6.66%) was more than 6%. When compared with 30 other species of Artemisia from the Hindu Kush–Himalayan region, they have the same major essential oil compounds. However, A. nanschanica has some significant characteristics as a species of subgen. Dracunculus, and has a large amount of aromatic compounds in its essential oil. A. nanschanica is a good raw source of chemical products and medicinal compounds, such as bisabolol, guaiene, and 1-ethylidene-1H-indene, that will be further enhanced by more study and development.
