monoterpene

Any of a number of substances (e.g., limonene, perillyl alcohol) that consist of two isoprene units and have the molecular formula C10H16. They are major components of essential oils, are found in fruits, vegetables and other plants, and have antioxidant and carcinopreventive activity.
 
Monoterpenes induce the expression of phase-I and -II hepatic detoxification enzymes, selectively inhibit protein isoprenylation (which targets proteins to membrane) and induce expression of the mannose G phosphate/IGF-II receptor and TGF-beta.

Moreover, in our study of the in vitro chemotaxis assay, fMLP was used as a chemotactic agent which promoted neutrophil migration and citral reduced the leukocyte migration, suggesting an anti-inflammatory activity of this monoterpene. These results were also correlated with a discrete lymphocytic infiltrate observed in citral-pretreated group obtained by histopathological observation of the liver.
