Organic solvent-soluble components of tobacco identified post

Organic Solvent-Soluble Components of Tobacco Identified Post-1955 

Neophytadiene a-Tocopherol Squalene Solanesenes Solanesyl esters 

Phytosteryl esters Long-chained aliphatic alcohols Long-chained ahphatic esters 

P ratios were calculated as molar yields or, as in Table XX V-6, as absolute quantities (micrograms of PAHs generated per gram of aliphatic tobacco hydrocarbons pyrolyzed). 

The lack of correlation between CSC content of B[a]P and specific tumorigenicity was demonstrated by Lazar et al. (2320), who reported that a 30-fold increase in B[a]P content by its addition to CSC produced no increase in the specific tumorigenicity to mouse skin of the B[a]P-enhanced CSC vs. the control CSC applied at equal dose levels. This lack of correlation between the B[a]P concentration in CSC and its specific tumorigenicity was also recognized by the U.S. Surgeon General, who wrote in 1981 [see p. 36 in (4009)]
