 Narcissus tazetta L. - Amaryllidaceae - bunchflowered narcissus, bunchflower daffodil , Chinese sacred lily, **Strauß-Narzisse**, Tazette
-Perennial herb, up to 80cm tall, native to the Mediterranean region and West Asia, cultivated (as ornamental) and naturalized there; leaves lanceolate, up to 40cm long; flowers in umbels up to 8, white-yellow to yellow-orange.
+Perennial herb, up to 80cm tall, native to the Mediterranean region and West Asia, cultivated (as ornamental) and naturalized there; leaves lanceolate, greyish-green, up to 40cm long; flowers in umbels up to 8, white-yellow to yellow-orange.
 Narcissus geranium = Narcissus x poetaz (= N. tazetta × N. poeticus) var.geranium : "From the large number
-of narcissus plant varieties available, 12 odorous species were collected, and a panel of perfumers selected the species treuithian and geranium as having the most interesting odor." \\
+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." \\

-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%). \\

+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%. Volatiles below 2% summed
+up to 14.59% of total emission. In summary, only two compounds, benzyl acetate and cis-β-ocimene can contribute 75% of the daytime scent emission. During the night emission, benzyl acetate and cis-β-ocimene
+contributed mainly to the scent, but their emission levels decreased, comprising lower proportions of the total than during daytime with 30.74% and 27.24%, respectively. \\
+Compound flowers emitted 11 different major compounds during daytime. The most abundant compound was cis-
+β-ocimene with 21.85%, followed by benzyl acetate with 19.33%. Five compounds accounted for between 8 and 5%, including eucalyptol, acetic acid penylethyl ester, hydroxycinnamyl acetate, benzene tert-butyl-benzene and β-linalool. Indole, 1,3-bis(1,1-dimethylethyl) benzene and 2-buten-1-ol-3-methylacetate accounted each for approx. 2% to VOC, while the total of minor compounds accounted for 16.56%. During the evening, cis-β-ocimene and benzyl acetate also formed the principal volatiles (Fig. 4). Cis-β-ocimene declined slightly to 21.19%, while the proportion of benzyl acetate increased to 21.65%, constituting the most prominent VOC." \\
