| GC-MS analysis of vacuum headspace samples of the flower scent showed main components with floral-rosy-citrusy notes like citronellal, citronellol (9.6%), citronellyl acetate (1.1%), geranyl acetate (3.3%), nerol (1.3%), geraniol (8.4%), benzyl alcohol (35.2%), phenylethyl alcohol (0.78%), geranial + benzyl acetate (0.96%), neral (0.02%), phenylacetonitrile (3.0%), farnesol (1.9%) and 2,3-dihydrofarnesol (0.88 %); green-grassy notes like (Z)-3-hexen-1-ol (10.6%), (Z)-3-hexenyl acetate (7.8%), (E)-2-hexenal (0.18%), and (Z)-3-hexenal (trace); fatty, waxy, aldehydic notes like octanal (0.15%), nonanal (0.1 %), and decanal (0.07%). \\ | GC-MS analysis of vacuum headspace samples of the flower scent showed main components with floral-rosy-citrusy notes like citronellal, citronellol (9.6%), citronellyl acetate (1.1%), geranyl acetate (3.3%), nerol (1.3%), geraniol (8.4%), benzyl alcohol (35.2%), phenylethyl alcohol (0.78%), geranial + benzyl acetate (0.96%), neral (0.02%), phenylacetonitrile (3.0%), farnesol (1.9%) and 2,3-dihydrofarnesol (0.88 %); green-grassy notes like (Z)-3-hexen-1-ol (10.6%), (Z)-3-hexenyl acetate (7.8%), (E)-2-hexenal (0.18%), and (Z)-3-hexenal (trace); fatty, waxy, aldehydic notes like octanal (0.15%), nonanal (0.1 %), and decanal (0.07%). \\ |
| Important trace components could be revealed by GC sniffing analysis, like (Z)-3-hexenal, green pea and galbanum-like notes like 2-isopropyl-3-methoxypyrazine and 2-isobutyl-3-methoxypyrazine, fruity-raspberry notes like β-ionone, and green-fatty and cucumber notes like (E,Z)-2,6-nonadienal and (E,Z)-2,6-nonadienol. \\ | Important trace components could be revealed by GC sniffing analysis, like (Z)-3-hexenal, green pea and galbanum-like notes like 2-isopropyl-3-methoxypyrazine and 2-isobutyl-3-methoxypyrazine, and fruity-raspberry notes like β-ionone. \\ |
