Can particular allergenic compounds be reduced while retaining the complex scent of oakmoss? This study used an enzyme to change their properties and separate them from the fragrance material.

How do fresh patchouli leaves, dried leaves, and essential oil differ in scent? This study explored the relationship between minor constituents and manufacturing steps, which the main compounds alone cannot fully explain.

Known for its green notes, galbanum also contains compounds that do not readily evaporate. This study examined the structures and amounts of the material left behind, as well as the fraction released into the air, to better understand the ingredient as a whole.

Fresh and dried roots from four Iranian vetiver accessions showed compound-dependent changes in relative essential-oil composition.

Experiments on Réunion compared flower storage and harvest times, separating oil yield and relative composition from untested sensory quality.

A pilot study tested whether brief cold-plasma pretreatment could improve lavender oil recovery and reduce distillation time and energy.

Four rose species extracted with the same liquefied-gas solvent showed different relative chemical profiles, without establishing an odor-quality ranking.

A 2024 study explores selective enzyme routes to four sandalwood fragrance ingredients, with distinct stereochemical and environmental trade-offs.
