The flower scent of O. fragrans, an Oleaceae native
to East-Asia, is dominated by carotenoid derived compounds.
β- and α-ionone are the most abundant scent
constituents and importantly contribute to the scent
perception of flowers of O. fragrans (Wang et al., 2009;
Baldermann et al., 2010). Commercial extracts are of economic
importance due to their application in expensive
cosmetics or for flavoring of foods, tea, and sweets.
