 of narcissus plant varieties available, 12 odorous species were collected, and a panel of perfumers selected the species trevithian and geranium as having the most interesting odor... there is only a very limited number of components which are common to most Narcissus varieties: some higher n-alkanes, some cresols, benzyl acetate, methyl benzoate and benzyl benzoate, some terpenoids such as limonene, p-cymene, ocimene, linalool, terpinen-4-ol,​ 1,​8-cineole,​ and α-terpineol,​ benzyl alcohol and phenethanol,​ 1-nonanal, and indole... On the basis of our findings, we agree with Loo and Richard (1986) that no character impact compounds are present in Narcissus."​ \\ of narcissus plant varieties available, 12 odorous species were collected, and a panel of perfumers selected the species trevithian and geranium as having the most interesting odor... there is only a very limited number of components which are common to most Narcissus varieties: some higher n-alkanes, some cresols, benzyl acetate, methyl benzoate and benzyl benzoate, some terpenoids such as limonene, p-cymene, ocimene, linalool, terpinen-4-ol,​ 1,​8-cineole,​ and α-terpineol,​ benzyl alcohol and phenethanol,​ 1-nonanal, and indole...

 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%). Minor components were e.g. α-terpineol (0.2%), methyl cinnamate (0.1%), phenyl ethyl acetate (0.3-1.1%), 3-hexenyl acetate (0.1%), and indole (0.3%)\\ Volatiles of single-flowered and double-flowered Chinese narcissus were identified by headspace-solid phase microextraction (HS-SPME) coupled with GC and GC/MS.
