In short
Methyl jasmonate is a natural constituent of jasmine and a plant hormone. It has a soft, sweet jasmine-floral odour and is the unsaturated relative of methyl dihydrojasmonate (Hedione).
What Methyl Jasmonate smells like
Methyl jasmonate is one of the key odorants of jasmine: sweet, floral and jasmine-like, with a green, herbal side. A trade description puts its sweetness and diffusive power well beyond Hedione's, for which Hedione serves as an economical substitute. Only some of its stereoisomers actually smell of jasmine, so commercial quality varies.

What makes Methyl Jasmonate distinctive
It is the richer, sweeter, more natural jasmine that Hedione lightens and dilutes — closer to the flower, less airy.
How Methyl Jasmonate is used
Used in jasmine reconstructions and fine floral compositions where a natural, sweet jasmine is wanted.
Typical role: modifier (used in small amounts to change the character of a blend).
How Methyl Jasmonate differs from similar materials
- Hedione
- A trade listing describes Hedione as lacking methyl jasmonate's overwhelming sweetness and diffusive power; Hedione is airier and more transparent. (compared directly by a cited source)
- cis-Jasmone
- cis-Jasmone is greener and herbal, with celery seed and tea; methyl jasmonate is the sweeter, more floral jasmine.
An asterisk marks a difference that a cited source states directly. The others compare the published descriptions of each material. Smell varies with grade, supplier and dilution; compare them side by side on blotters before substituting one for another.
