What is solanesol in tobacco?
The leaf tobacco contains the tobacco-specific compound solanesol. It is found in tobacco smoke and in the emissions of heat-not-burn tobacco products. Tobacco has the highest solanesol content amongst all solanaceous plants. It is extractable from tobacco waste.
Is solsolanesol a noncyclic alcohol?
Solanesol is a non-cyclic terpene alcohol that consists of nine isoprene units and mainly accumulates in solanaceous plants such as tobacco, potato, and tomato. It is also accumulates in eggplant and pepper plants. It is notable as the biosynthetic precursor to coenzyme Q 10.
What is solsolanesol and why is it important?
Solanesol serves an important role in the interactions between plants and their environment, and it is a key intermediate for the pharmaceutical synthesis of ubiquinone-based supplements and drugs.
