摘要：An excellent variety of damask rose (Rosa damascena Mill.), named rose de resch introduced from Bulgaria, was subjected in this research conducted in western suburb of Beijing. Using the technique of dynamic headspace collection, the volatiles emitted from the naturally growing flowers were collected in the sequence of developmental stages. Then, by the means of thermal-desorption cold trap/gas chromatography/ mass spectrometer technique (TCT-GC/MS), constituent compounds of the volatiles were identified. Total of 89 volatile compounds were detected and identified from fresh flower of rose de rescht at four stages including bud stage, half-blooming stage, full-blooming stage and senescing stage. The constituent compounds were categorized into alcohols, terpenes, esters, aldehydes, ketones and alkanes. Among them, aldehydes, terpenes and alkanes were the major aromatic constituents. However, the aromatic constituents changed greatly at different developmental stages. At full-blooming stage, the flowers emitted most diversified aromatic volatiles, and reaching the summit of relative abundance.
