Sterol Content in Cigarette Tobacco and Smoke

Abstract

Cholesterol-4-14C and b-sitosterol-4-14C were incorporated into cigarettes and their presence in mainstream smoke was studied. The transfer of 14C-labelled cholesterol to mainstream smoke was 20.27 %, of which 16.25 % was in trapped smoke condensates and 4.02 % in butts; only 0.004 % was in ashes. The transfer of 14C-labelled b-sitosterol to mainstream smoke was 16.20 %, of which 13.11 % was in trapped smoke condensates and 3.09 % in butts; only 0.007 % was in ashes. The relative composition of free sterols, steryl esters, and bound glycosides in cigarette tobacco and in trapped smoke condensates was also studied. Fractions of free sterols and steryl glycosides were higher while fraction of esters was lower in trapped smoke condensates as compared to cigarette tobacco. Comparison of four individual sterols (cholesteroI, campesterol, stigmasterol and b-sitosterol) was studied in cigarette tobacco and cigarette smoke (smoke condensates, butts, wrapping papers from butts). A slight increase of cholesterol was noted in smoke condensates and wrapping papers from butts.

Phenols in Tobacco Leaves and Tobacco Smoke / Über die phenolischen Inhaltsstoffe des Tabaks und des Tabakrauches

Abstract

This paper reviews

1.the plant phenols occurring in tobacco leaves, and 2.the phenols of tobacco smoke. These constituents are summarized in

2 tables. The leaf contains mainly quinic acid esters of hydroxy-cinnamic acids (chlorogenic acids), flavonol-glycosides, and hydroxy-coumarins. Main constituents are chlorogenic acid and rutin. Tobacco smoke does not contain these compounds, but a number of simpler phenols and phenol ethers, and phenolic acids. Besides this paper describes the transformation of plant phenols by the curing of tobacco, such as the formation of brown complex products from chlorogenic acid and rutin. Furthermore, the biosynthesis of plant phenols, their importance for the quality of tobacco, their phytopathological importance, and the effect of phenols occurring in tobacco leaves and tobacco smoke on the human organism are shortly reviewed
