Nerolidol is a naturally occurring sesquiterpene alcohol valued for its floral aroma and broad pharmacological activities, including antimicrobial, antioxidant, and anti-inflammatory effects.
Chemical Structure and Properties
Nerolidol (C₁₅H₂₆O, MW 222.37) features a 12-carbon chain with three double bonds (typically trans-trans configuration) and a tertiary hydroxyl group at position 3, contributing to its characteristic woody-floral scent. Its lipophilicity (logP 4.9) facilitates efficient skin penetration, while its volatility supports applications in essential oils and fragrance formulations.
Isomeric forms such as (E,E)-nerolidol predominate in nature and play a role in biochemical processes, particularly as intermediates derived from farnesyl pyrophosphate in terpenoid biosynthesis.
Natural Sources and Extraction
Nerolidol is found in a variety of plant essential oils, including those derived from orange, ginger, tea tree, and rose. It is commonly extracted via steam distillation from plant materials such as flowers, leaves, and fruits. Its biosynthesis occurs through the mevalonate pathway, where it is generated by the dephosphorylation of farnesyl pyrophosphate.
