What Are Terpinene and Terpineol Compounds?

Terpinene and terpineol compounds are monoterpenoid compounds found in turmeric's essential oils from various parts of the plant (leaf, flower, root, and rhizome). Alpha-terpineol is found in all parts of turmeric, but the flower contains most of it. Gamma-terpinene and terpenoline have only been found in the leaf. ^{(ii.1, 7, 11, 15, 20, 24, 25)}

• Terpineol compounds (including γ-terpinene) are antioxidants. They are also ACE inhibitors, which mean they could help keep your heart healthy.
• Research suggests terpineol can inhibit cancer growth.
• Alpha-terpineol has sedative properties that may help reduce anxiety.
• Alpha-terpineol and terpineol have antiseptic and antibacterial properties.
• Alpha-terpineol acts as an organic insecticide against pests that attack garden vegetables (such as the European corn borer). Terpineol compounds can also kill house fly eggs.
