| | Main components of the headspace of Rosa gallica flowers collected on Tenax were alcohols like phenylethanol (41.8%) and nerol (2.6%), esters like geranyl acetate (18.1%) and phenylethyl acetate (7.7%), and sesquiterpenes like germacrene D (4.4%), and bourbobene (2.1%). \\ |

| Pentane/dichloromethane extracts of Rosa gallica petals showed phenylethanol as the main component (highest content of all old roses, up to 89.9%), followed by hydrocarbons (up to 28.5%). Other components were benzyl alcohol (0.2-10.6%), nerol (0-18.6%), geraniol (0.1-30.6%), geranyl acetate (0-4.4%), benzyl benzoat (0.1-1.0%) and nonanal/cis-rose oxide (0-0.2%). 4-Vinylphenol (0.2-10.6%) was detected in two samples of Rosa gallica. \\ | Pentane/dichloromethane extracts of Rosa gallica petals showed phenylethanol as the main component (highest content of all old roses, up to 89.9%), followed by hydrocarbons (up to 28.5%).
