-Volatiles of single-flowered and double-flowered Chinese narcissus were identified by headspace-solid phase microextraction (HS-SPME) coupled with GC and GC/MS. The main constituents were (E)-β-ocimene (62.7%-66.0%), benzyl acetate (11.6%-25.0%), (Z)-β-ocimene (1.8-4.6%), 1,8-cineole (1.4-4.0%), prenyl acetate (1.2-2.1%), and linalool (1.1.-1.7%). \\+Volatiles of single-flowered and double-flowered Chinese narcissus were identified by headspace-solid phase microextraction (HS-SPME) coupled with GC and GC/MS.

 Narcissus spec.: "Six volatile compounds with a percentage above 2% were identified in the simple flowers. Daytime volatile profile revealed benzyl acetate as major compound with 37.35%, followed by cis-β-ocimene with 34.86%. Further important volatiles were indole with 4.61%, 1,2-bis(1,1-dimethylethyl)-benzene with 3.57%, trans-β-ocimene with 2.32%, 2,4-bis(1,1-dimethylethyl)-phenol with 1.95% and dodecane with 0.75%.
