| introduction | menthone is a monoterpene compound. it exists in the volatile oil of mint, nepeta, scutellaria baicalensis and agastache. it is a colorless oily liquid with mint-like aroma, slightly soluble in water, soluble in ethanol and most organic solvents. |
| biological activity | Menthone is one of the main volatile components of mint essential oil (Mentha piperita L.). Menthone can be used as an antioxidant, with a good compensatory effect, which can significantly reduce DNA damages in sperm cells. |
| use | is a spice for preparing geranium oil. it is used in trace amounts in citronellol or in flower fragrance essence such as roses. it has the function of promoting flower fragrance and is used in appropriate amounts in lavender, fragrant Wei, spicy fragrance and other spices. It is the raw material for edible cool flavors. It is used for fruit flavors such as Rubus. It can improve the flavor, increase the freshness and reduce the sweet taste. It is also a good spice for toothpaste. menthone (trans isomer) and iso-menthone (cis isomer) both have mint aroma and can be used to prepare mint series essence. |
| production method | menthone is contained in peppermint and peppermint oil, as well as essential oils such as geranium oil and beech oil. The fraction at 204-212 ℃ can be cut by vacuum distillation, converted into oxime or semicarbazide, recrystallized, and pure menthone or iso-menthone can be separated. Menthone can be obtained by reducing menthone or piperone. |
