| Main components of the headspace of flowers of the beautiful hybrid tea rose //‚Baronne E. De Rothschild’// (purple-Solferino petals with a silvery reflection on the underside), collected on Tenax, were esters (91.1%), with large amounts of (Z)-3-hexenyl acetate (45.1%) and hexyl acetate (32.9%). \\ | Main components of the headspace of flowers of the beautiful hybrid tea rose //‚Baronne E.

| //,Sutters Gold‘// (with copper yellow petals veined by orange and carmine) is characterized by an oriental rose scent with fruity (cherry) and cognac undertones. The dominating esters (75.5%) included (Z)-3-hexenyl acetate (23.7%), hexyl acetate (26.8%), phenylethyl acetate (16.3%), and geranyl acetate (4.2%). Orcinyl dimethylether (3,5-dimethoxytoluene; DMT; 14.2%) was distinctly present, together with phenylethanol (3.2%), nerol (2.8%), citronellol (1.8%), and also the rose oxides (0.18%). \\ | //,Sutters Gold‘// (with copper yellow petals veined by orange and carmine) is characterized by an oriental rose scent with fruity (cherry) and cognac undertones.

| The hybrid tea rose //'Fragrant Cloud'// ([[https://de.wikipedia.org/wiki/Duftwolke|'Duftwolke']], 'Fragrant Cloud'), the most abundant components were esters (48.8%) like phenylethyl acetate (19.3%), hexyl acetate (12.3%), (Z)-3-hexenyl acetate (9.7%), and citronellyl acetate (7.1%). Olfactorly interesting compounds were also phenylethanol (14.8%), citronellol (5.8%), p-vinyl anisole (11.0%), β-ionone (0.7%), rose oxides (0.2%), and estragol (0.1%). \\ | //'Meispola'// ('Yonina') is a variety of hybrid tea rose with distinctive elegant double pure white blossoms having a delicate fragrance. Main group of components were esters (55.8%), like (Z)-3-hexenyl acetate (26.5%), hexyl acetate (26.2%), and geranyl acetate (2.1%), alongside 3,5-dimethoxytoluene (DMT; 29.0%) and citronellol (5%). \\ |
| | The hybrid tea rose //'Fragrant Cloud'// ([[https://de.wikipedia.org/wiki/Duftwolke|'Duftwolke']], 'Fragrant Cloud'), showed also esters esters (48.8%) as the most abundant components, like phenylethyl acetate (19.3%), hexyl acetate (12.3%), (Z)-3-hexenyl acetate (9.7%), and citronellyl acetate (7.1%). Olfactorly interesting compounds were also phenylethanol (14.8%), citronellol (5.8%), p-vinyl anisole (11.0%), β-ionone (0.7%), rose oxides (0.2%), and estragol (0.1%). \\ |
| | Ther are varieties containing mor than 40% of DMT ('aromatic ether type'). //'Sylvia'// ([[https://www.helpmefind.com/rose/l.php?l=2.16733.2|W.Kordes]]) had DMT (67.3%) together with anisole (0.1%), p-vinylanisole (1.1%), β-ionone (2.7%), rose oxides (0.5%), nonanal (0.9%), and decanal (0.9%). \\ |
| | //'Youki San'// ('Meidonq') showed DMT (55.8%), anisole (1.4%), p-vinylanisole (0.6%), together with hexyl acetate (3.3%), (Z)-3-hexenyl acetate (1.6%), and a tpiycal scent derived from phenylacetaldehyde (1%). \\ |
| | //'Papa Meilland'// is a dark velvet red tea hybrid rose with a lemon peel note added to the typical classical rose scent. Aromatic ethers present are DMT (40.3%), accompanied by benzyl methyl ether (2.7%), and p-vinylanisole (1.6%). Other major components were citronellol (29.4%), phenylethanol (1.8%), hexyl acetate (12.6%), citronellyl acetate (3.1%), rose oxides (1.5%), and β-caryophyllene (1.0%). \\ |
