Daphne mezereum L. - Thymelaeaceae - mezereon, february daphne, Gemeiner Seidelbast, Kellerhals
Deciduous shrub, 0.40-1.20m high, native to Europe and Western Asia; flowers cauliflor, dark pink or sometimes white, produced in early spring before the leaves; fruits red, ovoid.
The main volatile compounds of a dynamic headspace concentrate from D.mezereum flowers were linalool (49%), (E)-β-ocimene (16%), 2-phenylethanol (4%), jasmone (3%), benzyl alcohol (2%), and cinnamic alcohol (0.3%).

„The floral fragrance of the shrub Daphne mezereum in central Sweden was collected by means of the head-space technique and investigated by GC-MS and multi-dimensional GC. (S)-(+)-Linalool was the main constituent (95%) of the flower fragrance and its enantiomeric purity exceeded 99% in the samples. The (2S,5S)- and (2R,5S)-furanoid and the (3R,6S)- and (3S,6S)-pyranoid linalool oxide isomers constituted 2-5% of the fragrance.“

linalool stereo isomers: (S)-(+)-linalool (coriandrol: sweet, floral) and (R)-(-)-linalool (licareol: floral, woody lavender)
The main volatile compounds from D.mezereum flower scent, collected by the dynamic headspace method, were linalool (85.6%), (E)-β-ocimene (6.7%), hexadecane (3.7%), benzyl alcohol (0.9%), (E,E)-α-farnesene (0.7%), lavandulol (0.5%), (Z)-β-ocimene (0.6%), cinnamic alcohol (0.4%) and 2-phenylethanol (0.4%).
