Abstract

To interpret the fragrance type of different cultivars in Osmanthus fragrans, flower scent components and emission patterns in Yanhong Gui, Yu Linglong, and Hangzhou Huang were analyzed by means of solid-phase microextraction （SPME） coupled to gas chromatography-mass spectroscopy （GC-MS）. Results showed that the major characteristic scent compositions are similar among three cultivars including linalool, -ionone and -ionone, while the relative content were different. For all cultivars, the odour activity values （OAVs） of linalool reached a peak at full-blossoming stage then decreased gradually; whereas, OAVs of -ionone decreased gradually with the flower opening. For Yanhong Gui and Hangzhou Huang, the OAVs of -ionone decreased gradually during flower opening, and in Yu Linglong a low-high-low pattern emerged. In addition, the relative content of some terpene and ester components increased gradually during flower opening. Special scent components such as -Decalactone, cis-Linalool oxide, and trans-Linalool oxide were also noted. According to sensory judgment, Yanhong Gui had a light and sweet fragrance, Yu Linglong had a strong and sweet fragrance, and Hangzhou Huang had an elegant and fresh fragrance. Thus, the major characteristic scent components were similar among the three cultivars, but variations in OAVs for the characteristic scent compositions during flower opening and the appearance of some special scent components for certain cultivars most likely caused differences in scent fragrance and emission patterns. ［Ch, 5 fig. 4 tab. 34 ref.］
