Kigathi R.N., Weisser W.W., Reichelt M., Gershenzon J., Unsicker S.B. Plant volatile emission depends on the species composition of the neighboring plant community.

To fully capture the scent of a plant, we should separate its aromatic gas from its fiber, juice, wax, and sugars.
How that is done depends upon the plant’s composition and heat tolerance.
Yuzu scent is slightly sour and bitter with hints of sweet floral, and is quite similar to grapefruit scent.

Perfumes labelled ‘natural’ perfumes commonly use essential oils, absolutes and concretes instead of fragrance oils.

Essential Oils

The very best inhibitors of Mpro were benzoin Siam and Sumatra resinoids and rocket extracts with IC50 values in range of 3.41 to 5.24 µg/mL.
The application of water in steam form as a way to extract essential oils from plants.
Known for millennia, it was the Arabic doctor and philosopher, Avicenna, who perfected it in the tenth century.
The steam opens up the oil ‘cells’ and the oil becomes suspended in the steam as it passes out of the still via the ‘swans neck’ towards a condenser.
