„Poet's daffodil is cultivated in the Netherlands and southern France for its essential oil, narcissus oil, one of the most popular fragrances used in perfumes.“ https://en.wikipedia.org/wiki/Narcissus_poeticus

A vacuum headspace concentrate of the flowers contained mainly benzyl alcohol (21%) and α-terpineol (19%). Minor components were lilac alcohols (three isomers), lilac aldehyde (one isomer), dihydroactiniolide, and benzothiazolone.

„Another scent highly regarded for its intensity and complexity emerges from the absolute of narcissus (Narcissus poeticus). Initially, it exhibits a strong green, woody and earthy note, and only upon dilution additional sweet floral, heavy and balsamic notes are discovered.“
Main components of the odoriferous part of the absolute (20%) are α-terpineol (23.7%), trans-isoeugenol methyl ether (20.0%), benzyl benzoate (19.4%), coumarin (6.9%), benzyl alcohol (5.0%), Δ3-carene (3.4%), phenylethanol (2.2%), ethyl palmitate (2.2%), cinnamic alcohol (2.2%), phenylpropyl acetate (1.7%), 1,8-cineole (1.5%), caryophyllene (1.0%), and benzyl acetate (0.7%). Minor components are: β-ionone, epoxy-β-ionone, (E,Z)-2,6-nonadienal, and (E)-2-nonenal contributing a violet note; various phenols adding orange flower and ylang-ylang shades; methyl-β-orcinol carboxylate (evernyl), methyl everninate, and orcinol dimethyl ether adding woody notes; phenylacetonitrile, jasmine lactone and 1-p-menthen-9-al introducing floral shades.

„In case of narcissus, fragrance is extracted via hexane or petroleum ether solvent from flowers resulting in 0.2-0.3% concrete or by supercritical CO2 extraction resulting in a yield of 0.41% (Ehret et al., 1992; Ferri et al., 2009). In case of solvent extraction, it takes 1000 kg of flowers to produce 2kg of concrete or 750 g of absolute and the relative low productivity of absolute from narcissus makes it an expensive product, restricted to luxury perfumes.“
Headspace solid-phase microextraction (HS-SPME) and GC-MS were applied to analyze flower scent. Simple and double flower cultivars showed circadian emission patterns and produced significantly less scent during the night than during the day. Main floral scent constituents were e.g.:
Simple flowers: benzyl acetate (37.3%), (Z)-β-ocimene (34.8%), indole (4.6%)
Double flowers: (Z)-β-ocimene (21.8%), benzyl acetate (19.3%), 1,8-cineole (8.8%), phenylethyl acetate (8.4%), hydroxycinnamyl acetate (6.6%), tert-butyl benzene (6.1%), linalool (5.9%), indole (2.7%), 3-methyl-2-buten-1-yl acetate (2.0%)
