    Carbon-centered free radicals as intermediates to mainstream smoke carbonyls

    GERARDI A.R.; COLEMAN W.M. III
    R.J. Reynolds Tobacco Company, R&D, Winston-Salem, NC, USA
    Free radicals in cigarette smoke may contribute to harm associated with cigarette smoking, more specifically, contribute to oxidative stress and subsequent biological activity. A recent high throughput procedure for relative determination of 14 different ...

    Tobacco composition I: A quantitative chemical composition of tobacco in 2008, from a nutritional perspective

    DUBE M.F.; COLEMAN W.M. III; LAWSON D.M.; MORGAN W.T.
    R.J. Reynolds Tobacco Company, Winston-Salem, NC, USA
    A definitive quantitative breakdown of the components of tobacco is provided. Specific quantitative analyses were completed on a range of tobaccos, including, for example, flue-cured, Burley and Oriental tobaccos. The data provides a comprehensive ...

    Tobacco composition II: A quantitative chemical composition of 2008 green and cured Burley and flue-cured tobaccos

    LAWSON D.M.; DUBE M.F.; COLEMAN W.M. III; MORGAN W.T.
    R.J. Reynolds Tobacco Company, Winston-Salem, NC, USA
    This second tobacco composition study provides a definitive quantitative breakdown of the components of tobacco both green and cured. Specific analytical analyses were completed on a range of green and cured Burley and flue-cured tobaccos by internal and ...

    The influence of a humectant on the retention by humans of solanesol from cigarette smoke. (Part 2. Glycerin)

    MOLDOVEANU S.C.; COLEMAN W.M. III
    R.J. Reynolds Tobacco Company, R&D, Winston-Salem, NC, USA
    Two common humectants are used as additives in the cigarette manufacturing process, propylene glycol (PG) and glycerin. The humectants may influence the deposition of cigarette smoke in the human respiratory tract by affecting the hygroscopic properties ...

    New methodologies for qualitative and semi-quantitative determination of carbon-centered free radicals in cigarette smoke using liquid chromatography-tandem mass spectrometry and gas chromatography-mass selective detection

    GERARDI A.R.; COLEMAN W.M. III
    R.J. Reynolds Tobacco Company, R&D, Winston-Salem, NC, USA
    Several approaches were explored to develop a high throughput procedure for relative determination of 14 different carbon-centered free radicals, both acyl and alkylaminocarbonyl type, in cigarette smoke. Two trapping procedures using cyanoproxyl radical ...

    Qualitative and relative quantitative determination of carbon-centered free radicals in whole smoke from various cigarette types

    GERARDI A.R.; COLEMAN W.M. III
    R.J. Reynolds Tobacco Company, R&D, Winston-Salem, NC, USA
    Free radicals in cigarette smoke may contribute to harm associated with cigarette smoking, more specifically, contribute to oxidative stress and subsequent biological activity. Recently, a high throughput procedure for relative determination of 14 ...

    Evaluation of the effect of phytol on the formation of PAHs in cigarette smoke

    MOLDOVEANU S.C.; COLEMAN W.M. III
    R.J. Reynolds Tobacco Company, R&D, Winston-Salem, NC, USA
    Pyrolysis of phytol has been studied with various purposes, including the potential formation of polycyclic aromatic hydrocarbons (PAHs). When pyrolyzed in a quartz tube at 860 ± 5 °C in a flow of nitrogen (30 mL/min) phytol was reported to generate benzo ...
