“…The total terpenoids content decreases during prolonged extraction, while that of the paraffin’s increases, as expected. A comparative study of rose oil obtained through traditional technology and extracts obtained using supercritical CO 2 and R134a shows that the chemical composition of the extracts was dominated by 2-phenylethyl alcohol (56.6% in the subcritical sample and 46.7% in the supercritical one), while the main aroma constituents were found substantially higher in the oil [ 48 , 49 ]. A comparison between 1,1,1,2-tetrafluoroethane and the more polar CO 2 indicates that the former allows work at a lower pressure leading to much less degradation of the final products [ 50 ].…”

A comprehensive chemical profiling of 1,1,1,2-tetrafluoroethane (freon R134a) subcritical extracts from the main genotypes of oil-bearing roses, was performed by gas chromatography–mass spectrometry (GC/MS) and gas chromatography with flame ionization detection (GC-FID) in order to reveal the differences in their chemical composition. One hundred and three individual compounds were identified using GC/MS and their quantitative content was determined using GC-FID, representing 89.8, 92.5, 89.7 and 93.7% of the total content of Rosa gallica L., Rosa damascena Mill., Rosa alba L. and Rosa centifolia L. extracts, respectively. The compounds found in the extracts are representatives of the following main chemical classes: mono-, sesqui- and triterpenoids, phenylethanoids and phenylpropanoids and aliphatic hydrocarbons. Fatty acids, esters and waxes were found, as well. The study revealed that 2-phenylethanol is the most abundant component, ranging 9.0–60.9% followed by nonadecane and nonadecene with 5.1–18.0% geraniol (2.9–14.4%), heneicosane (3.1–11.8%), tricosane (0.1–8.6%), nerol (1.3–6.1%) and citronellol (1.7–5.3%). The extracts demonstrate a specific chemical profile, depending on the botanical species—phenylethanoids and phenyl propanoids are the main group for R. damascena, aliphatic hydrocarbons for R. alba and R. centifolia, while both are found in almost equal amounts in R. gallica. The terpenoid compounds show relatively broad variations: monoterpenes—11.9–25.5% with maximum in R. centifolia; sesquiterpenes—0.6–7.0% with maximum in R. gallica and triterpenes—0.4–3.7% with maximum in R. gallica extract.

“…Among these 19 compounds, 18 esters had never been identified before in other fragrant extracts from Rosa centifolia or Rosa damascena to our knowledge. The exception is phenylethyl linoleate, which was found in rose essential oil by Antonova et al in 2021 37 . Moreover, the occurrence of theses esters in other natural extract was further investigated.…”

Roses have beautiful shapes and colors, which make them attractive for horticultural purposes, and more than 18,000 varieties have been created by crossings. 1 Rose is also one of the major sources of natural ingredients for the fragrance industry. Indeed, the Queen of the flowers brings exceptional facets to perfume compositions. Among the 200 rose species, Rosa centifolia and Rosa damascena are the two main species used by the fragrance industry. 1 Rosa centifolia is mainly farmed in France and Morocco, 2,3 while Rosa damascena is mainly farmed in Bulgaria, Turkey, China, India and Egypt. 2,3 Rosa damascena is used to produce essential oil (yield: 0.03%), concrete (yield: 0.17%-0.40%), and absolute (yield: 50%-65% from concrete extraction), whereas Rosa centifolia is only used for concrete and absolute, and is not economically viable for essential oil. 4 Due to its rarity Rosa centifolia is one of the most precious species used in perfumery for absolute. Obtention of rose concrete from fresh rose flowers is a well-known process. Rose concrete is produced by solvent extraction, generally using petroleum ether and/or "generic" hexane. 2,[5][6][7][8] In contrast with recent allegations, 9 various mixtures of C6 hydrocarbons with low n-hexane content are preferred, rather than pure n-hexane, a CMR and neurotoxic substance. Benzene is no longer used for solvent extraction due to his high toxicity. 10 Moreover, to date extraction of fresh rose flowers with liquefied gases or supercritical CO 2 have not reached any significant importance. Rose concrete is a waxy, semi-solid material, that is, hardly soluble in ethanol. So, concrete is poorly used in its native form for fragrances and is further transformed into absolute using ethanol. Concrete is dissolved in hot ethanol (between 35 and 40°C) and then filtered at glacial temperature (−20°C). Ethanol is finally evaporated under vacuum to get the absolute. 2,6,11,12 Rose absolute is a dark red liquid with a typical rose odor. Rose absolute is considered to represent the more genuine character of rose fragrance. Indeed,

“…The biological activity of rose oil is due to its chemical composition. Many studies exist about the chemical content of rose essential oil of R. damascena from different origin [ 6 , 7 , 8 , 9 , 10 , 11 ] and of R. alba [ 12 , 13 ]. More than 300 different compounds are present in the rose oil from R. damascena [ 11 ] as well as about 214 in the rose oil from R. alba [ 12 ].…”

The steam distillation of valuable rose essential oil from R. damascena Mill. and R. alba L. generates large volumes of wastewaters. Although such wastewaters are bio-pollutants, they contain valuable bioactive compounds. In this study we investigated the cytotoxic/genotoxic and anti-cytotoxic/anti-genotoxic potential of these products. We used cytogenetic methods for induction of chromosome aberrations and micronuclei in two different experimental test-systems: ahigher plant and human lymphocyte cultures. Different experimental schemes of treatment with the waste products showed that the genotoxic activity of wastewater from the distillation of oils from R. alba and R. damascena was low in both test–systems. Human lymphocytes showed a higher sensitivity to the products than plant cells. Both types of waste products manifested anti-genotoxic effect against N-methyl-N′-nitro-N-nitrosoguanidine, a direct mutagen. The wastewaters obtained from steam distillation of rose essential oil have cytoprotective/genoprotective effect and could decrease DNA damage. Data are promising for further use of these products in pharmacy and other areas of human life.
