Methyl jasmonate is a ubiquitously common ingredient of plants. It is the methyl ester of jasmonic acid, and the latter as a phytohormone. Methyl jasmonate has a very broad, congruent in many parts of the jasmonic Range of action: inhibition of growth, involvement in senescence, forming so-called jasmonate -induced proteins ( JIP ) and protease inhibitors. The latter are part of the plant defense mechanism against herbivores which, by an eating -related mechanical damage to the plant, a release of jasmonates. The formation of secondary plant substances ( phytoalexins, such as having antibiotic activity ) is stimulated by jasmonates ( elicitor ) and so is response to damage by pathogenic microorganisms.

Occurrence

Methyl jasmonate is a ubiquitously in the plant kingdom common ingredient. It is a component of jasmine oil.

Synthesis

The precursor of the methyl jasmonate is jasmonic acid, which is methylated by the enzyme jasmonate -methyl transferase at the first carbon atom.
