[Biosynthesis of beta-phenylethanol in rose petals].

Biosynthesis of beta-phenylethanol is studied in a cell-free rose petals extract. This compound found to be synthesized via two intermediates: either trans-cinnamic acid, or phenylacetaldehyde. Subsequently beta-phenylethanol is glucosodized into its transport form, beta-phenylethanol- beta-D-glucoside.
