两种类型的切花，玫瑰（Rote rose）和婴儿呼吸（Gypsophilia elegans），当切花的茎浸泡在含有2-苯乙基β-d-葡萄糖苷（PEBG）的花瓶溶液中时，花香发生了巨大的变化。将未经处理的对照月季和放置在含有0.5% PEBG的花瓶溶液中的处理过的月季进行比较，从后者的小花中检测到的2-苯乙醇大约是前者的500倍。在用秀丽隐杆线虫进行的类似比较中，处理过的花的顶空不仅增加了2-苯乙醇的水平，而且降低了花的主要恶臭成分异戊酸和2-甲基丁酸的水平。这些结果表明，首先，PEBG可以作为切花的香味增强剂；其次，它可能在糖苷花的香味形成中起作用。版权所有©2003 John Wiley & Sons， Ltd
The floral notes of two types of cut flowers, rose (Rote rose) and baby's breath (Gypsophilia elegans), were dramatically changed when the cut stems were immersed in a vase solution containing 2-phenylethyl β-d-glucopyranoside (PEBG). In a comparison between an untreated control R. rose and a treated R. rose placed in a vase solution containing 0.5% PEBG, approximately 500 times more 2-phenylethyl alcohol was detected from the floret of the latter. In a similar comparison using G. elegans, the headspace of the treated flower not only had increased levels of 2-phenylethyl alcohol but also had decreased levels of isovaleric acid and 2-methyl butyric acid, the main malodorous components of the flower. These results suggested, first, that PEBG is useful as a fragrance enhancer for cut flowers, and second, that it may play a role in the fragrance formation of glycoside flowers.
