Abstract |
The essential oil was obtained from the aerial part of Hyang-mo (Hierochloe odorata (L.) P. Beauv.) by continuous steam distillation, samples were collected by solid-phase microextraction, and the compositions of the essential oil were analyzed by gas chromatography-mass spectrometry. The aerial part of 20-day-old hyang-mo contained 0.01% of essential oil. The frangrance of the aerial part was floral, oily, dusty, flat and powdery; however, that of the essential oils was floral, oily and dusty. In the essential oil, 44 constituents were found: 33 hydrocarbons, 2 oxides, 1 ketone, 1 ether and 1 CN compound. Major chemical constituents in the essential oil were ¥á-cubebene (34.44%), ¥ã-selinene (7.89$), en-in-dicycloether (7.75%), ¥â-caryophyllene (6.07%), calarene (4.20%), aromandendrene (3.47%), ¥ã-muurolene (2.93%), ¥ä-cadinene (2.73%) and ¥â-elemene (2.16%).
