| "Phenyl ethyl alcohol and citronellol are the major volatile constituents of peony flowers which give the 'rosy' character to their fragrance. The low boiling fraction [of the pentan extract from the petals] consisting of hexenal and hexenol isomers is responsible for the 'green' odour character. The extract lact monoterpene hydrocarbons, but contains large amounts of waxes, stearoptenes and fatty acids and esters." \\ | "Phenyl ethyl alcohol and citronellol are the major volatile constituents of peony flowers which give the 'rosy' character to their fragrance.
