中文摘要：

采用顶空固相微萃取-气相色谱-质谱联用技术分析了大马士革玫瑰花挥发性成分1d内随时间的变化及玫瑰花不同部位挥发性成分的差异．结果表明，花瓣中苯乙醇含量在12：00含量达到最大值，而香茅醇则在15：00含量达到最大值；玫瑰花瓣中醇类含量最高，为75．36％；玫瑰花蕊中酚类（丁香酚、甲基丁香酚）含量最高，达47．67％，醇类化合物有24．31％；玫瑰花托中，蒎烯类化合物含量达85．75％。

英文摘要：

Volatile composition changing over time and the differences volatile components in different parts of Damascus Rose was analyzed by headspace-solid phase microextraction gas chromatography-mass spectrometry （HS-SPME-GC/MS）. The results showed that the Phenyl ethanol content reaches its maxi- mum at 12：00 in rose petals, and the citronellol content reaches a maximum at 15：00. It is also found that the Alcohol compounds content is highest levels in rose petals, it accounts for 75.36%. The Phenol- ic compounds content is highest levels in rosebud, it is 47.67%. The second is the Alcohol compounds ,it is 24.31%. Pinene compounds content reaches the highest level of 85.75% in rose receptacle.
