| "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.
