Chinese Toon
Note Profile
About
The spring leaf shoot of Toona sinensis, smelled and eaten as a vegetable in China. It is an allium smell on a tree: onion and roasted garlic over a herbal top.
Scent Profile
Sulphurous is almost the whole note and two independent sources reach it by different routes. The PMC paper calls the aroma 'onion-like' and ties it to volatile sulphur compounds. China Daily says the same thing in kitchen words: 'a pungent roasted garlic aroma with maybe raw onions'. Aromatic_herbal is the other thing China Daily names, 'herb-like in its fragrance'. Green is the one facet no source states. It is scored from the organ, because the note is a spring leaf shoot, and it carries the widest spread in the vector for that reason. A fresh_spice prickle carries the pungency both sources report.
ScentWheel
Read off the wheel, not a label applied to the note.
Origin
Toona sinensis is a deciduous tree of the mahogany family, grown across China for its young shoots rather than its timber. The shoots are picked in spring. Their aroma comes from volatile sulphur compounds, which a 2025 PMC paper reports are 'predominantly thiophenes such as 2-mercapto-3,4-dimethyl-2,3-dihydrothiophene', working together with terpenoids. Growers split the tree into a 'fragrant toon' and a 'smelly toon' and the difference is in the shoots, so material sold under this name is not one fixed smell.
Usage in Perfumery
No perfumery trade or manufacturer source describing a Toona sinensis extract as a fragrance material was found. Every source located is food science or food writing. Treat this as a culinary reference note. If used at all it would sit where garlic and chive sit, in trace amounts as a savoury shock in an experimental composition.
