The scientific name of jasmonone is "3-methyl-2-(2-pentenyl)-2-cyclopenten-1-one". It is present in the volatile oil extracted from jasmine flowers. It can be found in jasmine oil (containing about 3%), orange blossom oil, geranium oil, lemon balm oil, and peppermint oil. It can be used to prepare jasmine fragrances, etc. 

As a spice, it can be safely used in food (FDA, §172.515, 2000).

Light yellow oily liquid. It has an elegant jasmine flower fragrance and celery seed aroma. Relative density (d422) 0.9437, boiling point 249℃, 134-135℃/1.6×10Chemicalbook3Pa, refractive index (nD22) 1.4979. It is slightly soluble in water, and soluble in ethanol, ether, carbon tetrachloride and oils. Natural products exist in jasmine oil, orange blossom oil, lemon balm oil, etc.。 

Limonolone is one of the valuable fragrances. Its aroma is very similar to that of jasmine flowers and it is one of the important fragrance components of jasmine oil. It is used in high-end jasmine series perfumes. Hydrogenation reduction of limonolone can yield dihydrolimonolone. Dihydrolimonolone is a slightly colored transparent liquid with a boiling point of 230℃ (102℃ at 0.67 kPa on Chemicalbook). It has a very strong floral fragrance and its chemical properties are relatively stable. It can be widely used in jasmine series perfumes. The industrial production of dihydrolimonolone is simple and there are various methods. In the presence of phosphoric acid, with the temperature controlled at 80℃ and the pressure at 0.007-0.011MPa, cyclizing nonadecanoic acid can produce dihydrolimonolone.
