| Sumario: | Rose-scented geranium (<i>Pelargonium</i> sp.) have been the subject of many studies concerning essential oil, unlike the edible flowers of scent <i>Pelargonium</i> despite the beneficial properties of chemical compounds present in such organ and the fragrances produced. Therefore, we investigated organic compounds, total phenols and the antioxidant activity of the flowers with particular attention to the volatile compounds emitted by flowers of <i>Pelargonium</i> ‘Endsleigh’ at three stages of development. We identified several major phenols and organic compounds that revealed significative difference compared with other <i>Pelargonium</i> flowers, and employing the solid-phase micro extraction (SPME) methodology we determined that the production of volatile compounds decreases during the flower development. In addition, the emission of volatiles is accomplished mainly by the sepals. In conclusion, to use <i>Pelargonium</i> ‘Endsleigh’ flowers, it is important in ensuring that they have not yet opened and that the sepals are in place. |
