Abstract:
The essential oil can be produced from fresh or dried plant. The aim of drying is to reduce the moisture content from actively growing in the field to a level that prevents deterioration of the product and allows storage in a stable condition. This study was carried out to investigate the essential oil constituents of the fresh and dried flowers of the R. damascena grown in North east of Iran. The results showed yield of essential oils from fresh and dried flowers of R. damascena were ۰.۰۵ % v/w and ۰.۰۱ % v/w respectively. Also a total of ۲۱ compounds were identified from fresh sample and ۳۲ compounds were identified from dried sample representing ۶۵.۹۷ % of the oil from fresh sample and ۵۳.۸۴ % of the dried sample. The major compounds in the fresh flower oil of plant were Geraniol, Nonadecane and Farnesol, while the oil of dried flower consists of Heneicosane, Nonadecane and Heptadecane. In conclusion there is a very significant difference in constituents of essential oils, because of drying conditions.
