Damask rose (Rosa damascene M). is one of the most important aromatic plants in the world. The objective of this study is to determine the composition and quality characteristics of dried Damask rose petals (DDRP) growing in Syrian conditions. Proximate components, microbial, chemical and physical properties of DDRP and its extracts were determined according to the standard methods. The results showed that DDRP have high total carbohydrate (75.21%), and crude protein (9.80%), and ash (3.88%) as source of micro, macro and trace elements, but low crude fat (0.96%), and moisture (7.20%). The initial total viable count (TVC) and total mould and yeast (TMY) were 2.29 and 2.10 log cfu-1, respectively. However, the properties of the DDRP extraction were determined to be; Total soluble solids (TSS) 1.77%, total acidity (TA) (0.77%), pH value (5.06), total volatile basic nitrogen (TVBN) (6.11 ppm), and viscosity (21.67 mP.Sc). The composition of DDRP and its extract are fulfilled in the recommended levels on national and international standards.
