Identification of Essential Oil Components in Chinese Endemic Plant Achnatherum inebrians

The chemical composition of the essential oil from the seeds and leaves of a Chinese endemic plant Achnatherum inebrians were analyzed for the first time by gas chromatography coupled with mass spectrometry (GC-MS). Forty-six and twenty-four volatile components were identified from leaves and seeds representing 93.74% and 85.13% of oils, respectively. The major components detected in the leave oil were 3-hexen-1-ol (9.45%), hexahydrofarnesyl acetone (7.61%), phytol (6.74%), 2H-pyran-3-ol (6.62%), benzyl alcohol (6.58%), and 2-methoxy-3-(2-proprnyl)-3-allyl-2-methoxyphenol (6.30%). However, n-butyl acetate (12%), benzene methanol (8.01%), 2H-pyran-3(4H)-one (6.95%), acetophenone (6.86%), 4-hydroxymethylacetophenone (6.42%) were the major components of the seed oil. Furthermore, various bioactive compounds were identified in both essential oils at different amounts, such as benzaldehyde, coumarin, and phytol.
