Abstract:
The characterization of chemical constituents of hydrodistilled essential oils
from the rhizomes of Distichochlamys citrea M.F. Newman and Distichochlamys
orlowii Larsen & M.F. Newman collected from Pù Mát National Park, Nghệ An
Province, Vietnam, was performed by means of gas chromatography-flame
ionization detector (GC-FID) and gas chromatography-mass spectrometry (GC-MS)
techniques. The main constituents of D. citrea oil were 1,8-cineole (23.0%),
(E)-citral (18.9%) and (Z)-citral (15.0%). On the other hand, geranyl acetate
(16.5%), β-elemene (9.2%), β-pinene (9.0%) and β-caryophyllene (7.9%) were
the principal components of D. orlowii. The present paper is the first of its
kind aimed at the characterization of the volatile compounds of D. orlowii.
