Sabinene

Sabinene is a natural bicyclic monoterpene with the molecular formula C₁₀H₁₆. It is isolated from the essential oils of a variety of plants including holm oak (Quercus ilex) and Norway spruce (Picea abies). It has a strained ring system with a cyclopentane ring fused to a cyclopropane ring.

Sabinene is one of the chemical compounds that contributes to the spiciness of black pepper and is a major constituent of carrot seed oil. It also occurs in tea tree oil at a low concentration. It is also present in the essential oil obtained from nutmeg, Laurus nobilis and Clausena anisata.
