Jasmonic acid  is a plant hormone that plays an important role in plant defense against insect pests and a natural plant constituent with growth-regulating properties. 

Jasmonic acid (JA) and its derivatives jasmonates (JAs) play a key role in plant metabolic processes and signaling systems when they are in stress and injured from pests (1).

JA and JAs are derived from fatty acid α-linolenic acid through the formation of different intermediates (2)and is found in apples, coffee,  tomato, tobacco and alfalfa leaves, while the esters are present in a kind of jasmine, Jasminum grandiflorum and give it its scent.
