"Commercial geranium oil consists in ca. 80% of euqal parts of (-)-(S)-citronellol and geraniol, along with small amounts of the corresponding formates and tiglates. Other compounds that are present in amounts of over 1% are (+)-menthone, (-)-isomenthone, (-)-R)-linalool, 2-phenylethanol, and eugenol methyl ether." More than 100 minor components have been identified, including eugenol, (-)-carvone, and (-)-rose oxide e.g. \\ | "Commercial geranium oil consists in ca. 80% of equal parts of (-)-(S)-citronellol and geraniol, along with small amounts of the corresponding formates and tiglates.
