Pulegone

Pulegone is a naturally occurring organic compound obtained from the essential oils of a variety of plants such as Mentha (mint), Nepeta cataria (catnip), and Pennyroyal. It is classified as a monoterpene and has a pleasant aromatic odor.

Chemical Structure and Properties

Pulegone is a colorless liquid at room temperature and has a strong minty aroma. Its chemical formula is C10H16O. The compound is a member of the class of compounds known as menthane monoterpenoids. These are monoterpenoids with a structure based on the hydrocarbon menthane backbone.

Sources

Pulegone is found in several plants including the Mentha (mint) genus, Nepeta cataria (catnip), and Pennyroyal. It is usually extracted from these plants through a process known as steam distillation.

Uses

Pulegone is used in flavorings, perfume, and aromatherapy. It is also used as a pesticide due to its strong aroma that is found to be repulsive to insects.

Health Effects

While pulegone has been used in traditional medicine, it is potentially toxic and can cause severe liver and lung damage if ingested in large amounts. It is also a potent abortifacient, which means it can induce abortion.

Regulation

Due to its potential toxicity, the use of pulegone in food and beverages is regulated in many countries. In the United States, the Food and Drug Administration (FDA) has banned the use of pulegone as a food additive.
