The leaf volatile components of Mexican Bursera linanoe were identified as ( R)-(–)-linalyl acetate (57.6%; 95.5% ee) and ( S)-(–)-germacrene D (39.3%; 100% ee) by solvent extraction and GC–MS and chiral GC analyses. Linalool was previously reported as the major component from the leaves of B. linanoe. However, we believe that this is a decomposition product of linalyl acetate during steam distillation, a common method for extraction of essential oils. The chemically unique blend in the leaves of B. linanoe may act as a chemical barrier against its potential herbivores, Blepharida beetles that have a tendency for attacking chemically similar plants as hosts.

Main Components

A comparative study of accelerated solvent extraction (ASE) with two conventional volatile isolation methods including traditional steam distillation and Soxhlet extraction was performed on lavender. ASE was carried out by butanol (polar protic solvent) or dichloromethane (nonpolar solvent) and the temperature was 120°C. Separation and identification of the components was carried out by GC/MS. The main components of the analysed samples were Linalool (14.79%), α-Terpineol (4.42%), Linalool oxide (furanoid) (2.92%), cis-linalyl oxide (2.8%), α-Bisabolol (1.86%) and Octacosane (1.56%) for steam distillation; for ASE (dichlormethane): β-Terpineol (2.06%), Linalyl anthranilate (1.82%), Largeracetal (1.82%), Eucalyptol (1.74%), Linalool (1.73%), Coumarine (1.28%) and Caryophylene oxide (1.08%); for ASE (butanol): Lageracetal (8.29%), Octacosane (1.75%), Eucalyptol (1.05%) and Caryophyllene oxide (1.02%) and for Soxhlet (butanol): Largeracetal (11.42%), Linalool (3.36%), Coumarine (0.83%) and Eucalyptol (0.74%). The study has shown that ASE is a fast and environmentally sustainable technique, using butanol and dichloromethane as solvent for the extraction of extractive compounds from lavender.
