Chemical investigation on Rose damascena Mill. volatiles; effects of storage and drying conditions

Abstract: The oil bearing rose (Rosa damascena) is the most important rose species in terms of fragrances and flavourings. Due to the very short blooming period and excessive amount of flowers, considerable amount of the rose flowers wait for a long time until distillation. There are losses of essential oil yield and quality use of before waited petals. The cold storage and drying applications may be alternative method for evaluate of excessive amount of flowers. Therefore in this study it was aimed to determine the effects of storage on cold (4°C) and room condition (25°C) and convective drying with different temperatures (40, 50 and 60°C) in terms of changes in volatile compositions of oil rose flowers based on direct hexane extraction. Totally 20 volatile compounds were identified in fresh, stored and dried rose petals. The detected compounds varied according to the various storage and drying conditions. It was determined that phenylethyl alcohol, citronellol, geranyl acetate, nonadecane were predominant compounds on all treatments. In the study, storing treatments led to increase on the percentage of oxygenated monoterpenes (OM) while drying treatments led to decrease on OM. It was determined that storing and drying treatments led to increase on the percentage of benzenoid compounds (BC) and aliphatic hydrocarbons (AH).
