-"Its diffusive, 'aromatic-spicy-floral' scent is extremly sweet. One would not expect to conatain more than 90% phenylethyl acetate; in fact, it is difficult even to detect this well-knon substance in the scent... the unusual accord is attributeable to minor constituents accompaning phenylethyl acetate, in particular beta-ionone and derivatives, coumarine, p-hydroxy phenylbutanone (raspberry ketone), and vanillin." \\

-Main component of the headspace of S.tigrina flowers was phenylethyl acetate (87-93%), minor components were e.g. benzyl acetate (1.4-3.2%), (E)-cinnamyl acetate (0-6.4%), and phenylethyl alcohol (0.7-1.5%). \\
