(Also known as: (-)-Jasomic acid) |
The following alerts are based on the data in the tables below. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement. These hazard alerts do not take account of usage patterns or exposure, thus do not represent risk.

Jasmonic acid is commercially produced through biotechnological methods that typically involve microbial fermentation. One notable approach uses the fungus Diplodia gossypina, which is cultivated under aerobic conditions in nutrient-rich media to biosynthesize jasmonic acid and its derivatives like methyl jasmonate. These microbes convert linolenic acid into jasmonic acid via a series of enzymatic reactions involving lipoxygenase, allene oxide synthase, and allene oxide cyclase. After fermentation, the jasmonic acid is extracted, purified, and sometimes esterified to enhance its stability and usability. |
