“…Tobacco leaf pigment has been shown to contain bound proteinaceous (or peptidal) material (9, 10) and nicotine (11). It was, therefore, not entirely unexpected to note the presence of characteristic degradation products of nicotine in pigment pyrolyzates (12).…”

The products resulting from the pyrolysis of tobacco and a number of nitrogenous organic compounds similar, if not identical, to those found in tobacco have been compared. Similarities have been noted in the composition of the various pyrolyzates, but essentially no physiologically active materials were found. Generalities with regard to pyrolysis of nitrogenous organic substances have been suggested by the data assembled.

“…Later work was conducted on the weakly acidic and strongly acidic subfractions of the condensate pigment (4,5). Most of the weakly acidic subfraction was found to be nondialyzable and to contain a component having a molecular weight of:>: 1oo,ooo, which yielded a silicone, nicotine and a series of bases on alkaline fusion (4). This represented the first report of nicotine bound in a high molecular weight structure in smoke condensate.…”

“…This represented the first report of nicotine bound in a high molecular weight structure in smoke condensate. Subsequently, the strongly acidic subfraction of the acidic condensate pigment was shown to be qualitatively similar to the weakly acidic subfraction (5). Most recently, 4 the nondialyzable weakly acidic subfraction was also found to contain significant amounts of fatty acids and bases (6) released by saponification and it is probable that the strongly acidic subfraction also contains such moieties.…”

“…The unfractionated acidic pigment contained iron, chlorogenic acid and a series of amino acids but most of the material was refractory to hydrolysis and alkaline fusion. Later work was conducted on the weakly acidic and strongly acidic subfractions of the condensate pigment (4,5). Most of the weakly acidic subfraction was found to be nondialyzable and to contain a component having a molecular weight of:>: 1oo,ooo, which yielded a silicone, nicotine and a series of bases on alkaline fusion (4).…”

“…Earlier reports alluded to the presence of y-sitosterol in tobacco (:1, :13); however, subsequent studies showed this material to be a mixture of P-sitosterol and campesterol rather than a single compound (14)(15)(16). One report (13) cited the presence of ergosterol in tobacco.…”

The influence of tobacco phytosterols (cholesterol, campesterol, stigmasteroI, b-sitosterol) on the chemical composition and biologicaI activity of tobacco smoke has been of concern to tobacco chemists. Therefore, a relatively simple method, utilizing a 14C-internal standard, chromatography on Sephadex and gas-liquid chromatography, was developed for the quantitative analysis of the phytosterols; this method was applied to the tobacco and smoke (mainstream and sidestream) of cigarettes and cigars to determine the fate of the phytosterols in burning tobacco. About 20 % of the total phytosterol content of tobacco was shown to be transferred intact into the smoke; about 2 % was possibly converted into polynuclear aromatic hydrocarbons. Radioactive tracer and pyrolysis studies were used to determine the nature of the phytosterol degradation products found in the smoke.
