with an optical rotation (.alpha..sub.D.sup.20) of +58.degree. are also novel. The process of our invention comprises the cultivation under aerobic condition of one or more specific strain of Diplodia gossypina in a nutrient medium followed either by (1) isolation of the jasmonic acid product or (2) esterification of the jasmonic acid to form methyl jasmonate followed by the isolation of the methyl jasmonate and novel products produced by such process.
