Abstract:
The volatile fragrance compounds released from fresh cut flowers of oriental lily ‘Siberia’ were analyzed by dynamic headspace collection and gas chromatography-mass spectrometry (GC-MS). The main aromatic ingredients were homomenthyl salicylate (25.98%); 1,6-octadien-3-ol; 3,7-dimethyl linalool (10.61%); 1-3-6-octatriene,3-7-dimethyl-cis-ocimene (7.81%); and hexadecanoic acid 1-methylethylester (6.54%). As related physiological indicators had been measured, the β wave and the galvanic skin response (GSR) of subjects increased after the inhalation of lily aroma, representing an increase in the sympathetic nervous activity as a reaction to linalool. Linalool, monoterpene alcohol, has obvious stimulating effects on human physiological and psychological responses. With the assistance of questionnaires, the study demonstrated that lily aroma has a high recognition. Most people choose commendatory terms, such as relaxed, excited, and enjoyable to describe the lily aroma.
