Oil-bearing rose (Rosa damascena Mill.) is one of the most strongly scented rose species, producing a high-value aromatic oil, which is used in the fragrance and cosmetic industries. In this research, developing the usage of natural and healthy products of oil-bearing rose and evaluating waste of distillation products were aimed. From this point of view, the main target in the study was to determine the essential oil and phenolic compounds, antiradical and antioxidant activities of rose oil and rose water as basic products, and also residue water as a waste product obtained in the distillation process of fresh oil-bearing flowers. Oil-bearing rose flowers were collected early in the morning hours of the days during the harvesting and processing season (May and June) from the research garden of the Rose and Rose Products Research Application Center (GULAR) at Suleyman Demirel University and then rose oil, rose water and residue water were obtained from the fresh rose flowers by using Clevenger type hydro-distillation apparatus. Essential oil compounds were analysed by gas chromatography/mass spectrometry (GC/MS). After phenolic extractions in the distillation products, total phenolics, flavanol and flavonol contents were analysed by spectrophotometric methods and phenolic compounds were determined by high performance liquid chromatography (HPLC). Antioxidant capacity was assessed by ferric reducing antioxidant power (FRAP) method, and antiradical activity was made by 1,1-diphenyl-2picrylhydrazyl (DPPH) method. Appreciation of the total results, citronellol in rose oil (35.27%) and phenylethyl alcohol in rose water and residue water (60.71% and 90.32%, respectively) were the main essential oil compounds. Rose oil had a rich content phenolics. On the other hand rose water contained more phenolic compounds according to the residue water. Antiradical and antioxidant activity were found high in the distillation products of oil-bearing rose. Rose oil and residue water among the distillation products had a higher antiradical and antioxidant activity when compared with rose water. As a conclusion, the results indicate that residue water as a large scale waste product during the hydro-distillation, can be evaluated for natural antioxidant sources to obtain economical gain.
