Ocimene

Ocimene is a group of monoterpenes that are used in perfumery due to their sweet, herbaceous, and woody aromas. They are found in a variety of plants and fruits, including mint, parsley, pepper, mango, orchids, and kumquats. Ocimene is also present in several essential oils such as bergamot oil and lavender oil.

Chemical Structure

Ocimene refers to several isomeric hydrocarbons. The ocimenes are monoterpenes and consist of the following isomers:

• cis-Ocimene
• trans-Ocimene
• alpha-Ocimene
• beta-Ocimene

Properties

Ocimene is a colorless to pale yellow liquid with a sweet, woody, and herbaceous odor. It is insoluble in water but soluble in alcohol and oils. It is used in the perfume industry and in aromatherapy for its pleasant odor.

Biological Role

In plants, ocimene and its derivatives are often used for their protective functions. They are part of the plant's defense mechanisms against herbivores and also have antimicrobial properties. Some studies suggest that ocimene may have potential therapeutic benefits, such as anti-inflammatory and antioxidant effects.

Safety

Ocimene is generally recognized as safe for use in food by the Food and Drug Administration (FDA). However, it can cause skin irritation in some individuals, and should be used with caution.
