The oral notes of two types of cut owers, 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 oret of the latter. In a similar comparison using G. elegans , the headspace of the treated ower 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 ower. These results suggested, rst, that PEBG is useful as a fragrance enhancer for cut owers, and second, that it may play a role in the fragrance formation of glycoside owers.
