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.

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.

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

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

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

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

Enzyme and chemical reactions selectively produced a Jessemal stereoisomer, with a 95% final-step yield but 18% overall yield.

A confined small-molecule catalyst favored the desired ambrox stereochemistry. Yield, selectivity, solvent recovery, and environmental limitations remain distinct questions.
