It was already reported that the metabolism of linalool and linalool derivatives can lead to the formation of lilac alcohols. In S. vulgaris only four out of all eight lilac aldehydes as well as alcohols were found [30]. Lilac aldehyde is of special interest for pollinators. It is emitted in high amounts, | + | |
