采用戊烷/二氯甲烷混合物提取24个不同品种的玫瑰花瓣，并采用气相色谱/质谱法对提取物进行分析。鉴定出大约30种化合物，以不同的组合分布在不同的物种或栽培品种中。主要成分是苯乙醇，但一些玫瑰显示出异常高的苯乙醇含量。在某些情况下，橙花醇和香叶醇也以相当高的浓度存在。在两个高卢玫瑰样品中检测到4-乙烯基酚。一些调味师进行了感官测试，以评估最有趣的提取物。
The petals of 24 different rose varieties were extracted with a pentane/dichloromethane mixture, and the extracts obtained were analyzed by gas chromatography/mass spectrometry. Approximately 30 compounds were identified, distributed in different combinations in the various species or cultivars. The main component was phenylethanol, but some roses showed unusually high levels of benzyl alcohol. In some cases nerol and geraniol were also present in considerable concentrations. 4-Vinylphenol was detected in two samples of Rosa gallica. A sensorial test was performed by some flavorists to evaluate the most interesting extracts.
