MAJOR AROMA INGREDIENTS OF ORIENTAL LILY 'SIBERIA' AND THEIR EFFECT ON HUMANS

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.
