Abstract

ABSTRACT With the objective to develop a scent database that could be used for perfume and cosmetics applications, a comparative analysis of the floral profiles close to one hundred odorous flowering plants found in Reunion Island has been undertaken for the last few years in our laboratory. A part of this work relating to three Hedychium species (the well-known H. coronarium but also H. flavescens and H. gardnerianum) is presented here. To achieve this, the solid-phase microextraction (SPME) on living flowers coupled to GC/MS was used. A total of 53 volatiles were identified belonging to aliphatic ketones, monoterpenes (hydrocarbons and oxygenated), sesquiterpenes (hydrocarbons and oxygenated), phenylpropanoids/benzenoids and miscellaneous. The phenylpropanoid/benzenoid and terpenoid classes were the main volatile classes. (E)-β-ocimene, linalool, (E,E)-α-farnesene, (E)-nerolidol, methyl benzoate, methyl salicylate, (E)-isoeugenol and indole were the major compounds detected. Results also revealed significant aroma variation among the different flowers.
留尼旺三种冬青花挥发物的比较研究
为了建立一个可用于香水和化妆品应用的气味数据库,我们的实验室在过去几年中对留尼旺岛发现的近100种有气味的开花植物的花卉特征进行了比较分析。本文介绍了有关三种Hedychium(众所周知的H. coronarium,但也包括H. flavescens和H. gardnerianum)的部分工作。为了实现这一目标,采用固相微萃取(SPME)对活花进行耦合GC/MS。共鉴定出53种挥发物,属于脂肪族酮、单萜(碳氢化合物和氧合物)、倍半萜(碳氢化合物和氧合物)、苯丙类/苯类和杂项。苯丙类/苯类和萜类是主要的挥发类。(E)-β-辛烯、芳樟醇、(E,E)-α-法脂烯、(E)-神经醇、苯甲酸甲酯、水杨酸甲酯、(E)-异丁香酚和吲哚是主要检测到的化合物。结果还表明,不同花的香气差异显著。
