Citronellol, or dihydrogeraniol, is a natural acyclic monoterpenoid. Citronellol is closely related to geraniol and has a floral, citrusy odor. There are two main types of citronella that contain citronellol as an active constituent: Ceylon and Java, named because of citronellol’s probable origin in Sri Lanka.
