Solanesol is an extract from tobacco. Solanesol is a terpene compound and an important intermediate of nutrients such as vitamin K2 and coenzyme Q10.

Solanesol research
I cannot find human research with solanesol so it is difficult to offer any statements at this time regarding the benefits or side effects of solanesol. I understand that extracts of solanesol are now being sold by raw material suppliers, one company has a 90% extract.

Solanesol as tobacco marker
Solanesol, a 45-carbon, trisesquiterpenoid alcohol found in tobacco leaves and tobacco smoke, has been used as a quantitative marker for tobacco smoke for years. However, solanesol appears to be unreliable as a quantitative marker for tobacco smoke during environmental air sampling because it can be degraded substantially when present as a component of tobacco smoke and by as much as 100% when present as pure solanesol on fortified filters during air sampling. Since there is strong evidence that ozone is the agent responsible for the degradation, solanesol appears to be unreliable as a quantitative marker during indoor air sampling when indoor levels of ozone are greater than about 15 ppb.
