[Chemical constituents of essential oil from roots and rhizomes of Valeriana alernifolia Bunge].
OBJECTIVE
To study the chemical constituents of essential oil from the root and rhizome of Valeriana alternifolia.


METHODS
The essential oil was extracted by steam distillation. The components were separated and identified by gas chromatography-mass spectrometry and elucidated on the standard mass spectral data and the percentages were determined by gas chromatographic area normalization method.


RESULTS
Twenty-eight constituents were identified, which make up 64.05% of the oil.


CONCLUSIONS
Bornyl acetate is the main constituent, and other constituents include borneol, terpinyl acetate, alpha-curcumene, camphene, isovaleric acid, trans-beta-farnesene, beta-bisabolene, etc.
